cadua.1mcgera,
Izgleda da se nova verzija (R13) priblizava neocekivanom brzinom.
Pojavile su se prve knjige i diskete sa uputsvima za R13 i pre
nego sto ja Autodesk krenuo sa prodajom, a to je siguran znak da
ce se R13 pojaviti za par meseci.
Gera,CADUA
cadua.2djcorto,
Najavljena isporuka R13 za kraj oktobra. Akcije Autodeska opale zato sto
su probili ocekivani rok za isporuku programa.

AutoCAD Data Extension (ADE)
For AutoCAD Release 12
We could all use connections like this.
What if you could access the data in all your AutoCAD drawings at
the same time-without compromising system performance?
Suppose you could quickly extract and consolidate just the data you
need into a new drawing, which could then be customized for
specific applications.
And what if you could do all this while someone else works with the
same drawings.
ARCHITECTURE, ENGINEERING AND CONSTRUCTION
Coordinate projects more easily, increase accuracy and shorten
turnaround time by providing simultaneous access to interrelated
drawings (architectural, structural, electrical, HVAC) and
producing custom or simplified drawings for team members and
subcontractors.
MAPPING, GIS AND INFRA STRUCTURE
Assist project management and planing by displaying content- or
location- specific portions of large maps or multiple drawings, and
applying ADE mapping and drawing customization tools.
MECHANICAL DESIGN
Increase efficiency by managing all mechanical engineering and
design processes concurrently. Extract and consolidate data from
multiple layout and 2D component drawings, and provide drafters,
designers and engineers simultaneous access to same drawings.
FACILITIES MANAGEMENT
Take control-and full advantage-of the wealth of data in multiple
AutoCAD drawings to plan reconfigurations, track and maintain
assets, and provide custom drawings for subcontractors.
PROCESS AND POWER INDUSTRIES
Ensure accurate and timely plant maintenance by quickly retrieving
relevant data from all P&IDs, plot plants, piping arrangements and
related EED or linked data bases to create custom plots.
TREAT MANY DRAWINGS AS THOUGH THEY WERE ONE
With ADE software, you can extract and combine drawing data from
many sources - AutoCAD drawing entities, attribute information,
related external database information-in a single session, without
additional hardware, without degrading system performance. The
first time you apply the ADE OPEN command to an AutoCAD drawing,
ADE software creates an index for it based on entity location and
AutoCAD properties. When you open multiple drawings, ADE simply
"activates" these indexes, so you can systematically access data
across all the open drawings. With this indexing system, the ADE
QUERY command can efficiently search through gigabytes of drawing
file data to quickly access the information you need.
EXTRACT JUST INFORMATION YOU NEED
Intuitive dialog boxes guide even novice AutoCAD users painlessly
through the ADE QUERY command. Simply click on a list of search
criteria for ADE, such as location (within circles, polygons,
windows, etc.), AutoCAD properties (color, layer, thickness, block
name, polyline area, etc.), EED (extended entity data) or external
database information. You can combine and modify search criteria
and save complex or frequent queries for later use.
CREATE CUSTOM DRAWINGS FOR SPECIFIC USES, EDITING OR ANALYSIS
As you access and consolidate selected information, you can use ADE
to customize your composite drawing, emphasizing specific drawing
elements by changing color, line width or other attributes. You
can make a global change to a set of drawings based on entity
properties or attached data. Or use ADE to explore and refine
design and layout options or client presentations.
MULTIUSER ACCESS TO DRAWINGS
ADE software allows multiple users simultaneous read-and- write
access to the same drawing files, with built-in safeguards to
control user access and editing. Entity locking,
administrative control over drawing access and AutoCAD software's
layer-locking feature prevent accidental overwrites and
unauthorized editing. While many users can work concurrently on the
same drawings, ADE ensures that each entity can only be edited by
one user at a time. ADE software's administrative controls include
options for password assignment and control over the level of
access individual users have to drawings. ADE is also fully
compatible with most network and database file security systems.
YOU CAN HAVE IT ALL NOW:
FASTER, BETTER, MORE INTELLIGENT DRAWINGS
ADE works with AutoCAD Release 12 and your existing AutoCAD Release
12 or Release 11 drawings-no file conversion, no labor intensive
data preparation. And ADE drawing productivity tools actually
enhance the design and drafting work you've done in AutoCAD. ADE
drawing cleanup features detect and clean up digitizing errors,
locate and eliminate duplicate entities, break lines at the point
of intersection and eliminate excessive detail in polylines (line
generalization). With ADE software's rubbersheeting feature, you
can easily align multiple drawings by "stretching" them to match
edges, lines and points.
ADE software's database interface is an efficient and easy-to- use
tool for linking AutoCAD entities to graphical and nongraphical
information in external databases and for accessing and
manipulating linked data. You can create links between AutoCAD
entities and database records, or access database records from
AutoCAD by selecting linked entities. Drawing entities can be
linked to items ranging from tabular data and spreadsheets to
videos and animations. Even complex SQL (structured query language)
statements are easy to construct with the ADE SQL Builder dialog
box.
SPEED IS MORE THAN COMPUTING TIME
ADE. It's about time. And accessibility. ADE software gives you
more comprehensive, more direct, more flexible access to your
AutoCAD drawings, which translates directly into spending less time
to accomplish your goals. And the program itself is easy to access.
It's easy to learn and easy to use, and it works with existing
data, so you spend less time ramping up (and more time saving
time).
AutoCAD Files Accepted Here-No Conversion Required
Because ADE works with your existing AutoCAD Release 12 and Release
11 files and external databases-exactly as they are in your
computer right now-you have immediate access to the benefits of ADE
software. (Or convert any CAD drawing into DXF format-ADE can work
with that, too.)
Haven't You Seen This Face Somewhere Before?
ADE appears as a menu item in AutoCAD Release 12, and uses AutoCAD
command syntax, dialog boxes and terminology. That means minimal
training for AutoCAD users. In fact, ADE software's dialog-box,
checklist approach makes it very accessible even for new or
infrequent AutoCAD users.
What's Behind the Curtain Does Not Matter
The ADE interface provides easy access to the wealth of data
contained in AutoCAD drawings-and you don't have to know a thing
about AutoCAD to get to it. Even users who are completely
unfamiliar with AutoCAD can step through simple dialog-box
instructions to access whatever drawing, EED and external database
information they need.
Streamline Computing Time
ADE activates AutoCAD drawings but physically brings into the
drawing editor only those portions you specify. Remaining portions
of the drawings and associated databases don't draw on system
resources. When you use ADE software to bring a subset of drawing
information into the drawing editor, it's usually faster than
working on a single AutoCAD drawing in its entirety.
Cut to the Quick
ADE gives you access to the vast amount of data in your AutoCAD
drawings, then quickly cuts through it to locate just the
information you need. The time savings is tremendous. Previously,
this kind of data search might have required hours of consolidating
and sorting trough information from different drawings individually
to find the right information. What was potentially overwhelming is
now a fast, efficient query away.
You Get the Picture
ADE software delivers precisely the information you need, then
provides tools for customizing drawings to graphically emphasize
ideas for you or your audience. Whether you're reviewing options
yourself or trying to sell an idea to someone else, with ADE you
spend less time gathering data, so that you can make more informed
decisions, faster.
Sharing the Wealth of Information-Selectively
No more information overload. ADE software lets you isolate
portions of drawing data, making it easier to share information
with other team members or clients. Both electronic files and
hard-copy reports are more manageable and often more effective when
focused on a specific application or data set.
Sharing the Work Load
Using ADE to coordinate individual activities in team projects
speeds up turnaround time and improves quality and overall group
performance. Because teams can work concurrently from the same
source drawings (without extensive restructuring) , preparation and
total project time are reduced. Team members can access and view
other drawing layers, so drawings match more closely. Consolidation
of layers is much smoother, too, especially with the drawing
cleanup tools in ADE software.
ADE. ISN'T ABOUT TIME?
With ADE, you'll spend less time gathering data and eliminating
irrelevant data. Less time waiting to access drawings someone else
has. Less time preparing for and coordinating team projects. Less
time getting decisions made and less time turning projects around.
Which, of course, translates into more time to take on new projects
and more time to perfect your designs. It's an entirely new way to
work with AutoCAD software.
SYSTEM REQUIREMENTS

cadua.5sceka,
Evo jednog pitanja za razmisljanje
Mozda cemo biti u prilici da pravimo neku vrstu kataloga
ili bolje receno podloge za projektante proizvoda jedne
firme koja pravi raznu armaturu (ventili,zasuni,..).
Zanima me vase misljenje kako bi trebalo to da izgleda
i da radi ne samo za tu firmu nego uopste i za ostale
firme tj. kako bi projektanti mogli to najbolje da iskoriste
prilikom projektovanja na CAD programima konkretno na
AutoCAD-u.
SO PROJEKTANTI DA VAS CUJEMO
Pozdrav
sceka,CADUA
cadua.6bobby.quyne,
Ja imam iskustva u radu sa takvim katalogom koji je za svoje proizvode
napravila firma FESTO, koja proizvodi pneumatske cilindre, ventile i
slicno. Katalog je vrlo lak za upotrebu, i popriliŔno je veliki, s
obzirom da FESTO ima nekoliko hiljada stavki u svom proizvodnom programu.
Ako zelis da vidis kako izgleda, mozemo da se dogovorimo o prezentaciji.
Inace, katalog je dodatak na ACAD pocevsi od verzije 10.
cadua.7djcorto,
>> firme tj. kako bi projektanti mogli to najbolje da iskoriste
>> prilikom projektovanja na CAD programima konkretno na
>> AutoCAD-u.
Ja odavno kukam za recimo katalozima namestaja u DWG formatu, a ne bih
apsolutno nista imao ni protiv vrata, prozora, spustenih plafona i sl.
Po mom misljenju, prava stvar je gomila blokova, sa pripadajucim
bibliotekama slajdova i menijem (tj dodatkom meniju) i, za R12, potrebnim
DCL-ovima .... eh ;(
Jos bi lepse bilo imati namestaj u 3D .... ;)
Ovde se postavlja pitanje layera, dimenzija (mm, cm, m, km, svetlosna
godina ..) i jos gomila slicnih ....
dJOLE, CADUA
cadua.8meda,
Zahvaljuju}i Zoranu Radovanovi}u, ~lanu CADUA, koji je boravio na
Sajmu INVEX u Brnu u drugoj polovini oktobra, imate ekskluzivan
izve{taj sa ove velike manifestacije, u oblasti CAD i CAM
tehnologija.
Posle Me|unarodnog sajma Informacione tehnologije "INVEX Computer
Brno" odr`anog od 19-22.10 94. nalazio sam se pred te{kim zadatkom
da taj zaista veliki skup opi{em koliko toliko sa`eto.
Posle nabavljanja, na `alost obaveznih, viza za Slova~ku i ^e{ku
mogao sam da krenem . I kona~no posle, u principu, OK putovanja i
mnogobrojnih carina stigao sam u Brno.
Odmah se videlo da se ovde odvijaju velike promene. Panoe sa
parolama su zamenili panoi sa reklamama. Ali promene }u najbolje
videti, kako se ispostavilo, na ~etvrtom INVEXU. Ulazi sajmi{ta su
od samog po~etka sajma bili zakr~eni srednjo{kolcima i poslovnim
svetom. Posle, za ^ehe karakteristi~nog strpljivog, ~ekanja u
povelikom redu, moj ~e{ki prijatelj i ja kupili smo karte, katalog
i dali se u obilazak zaista velikog sajmi{ta. Od mog prijatelja sam
saznao da je sajam tehnike skoro duplo ve}i.
Hale su, prili~no grubo, bile podeljene na oblasti CAD, HARDWARE,
SOFTWARE, KANCELARIJSKA OPREMA itd. Situacija je po mapi sajmi{ta
izgledala otprilike ovako: jedna hala CAD, tri hale kancelarijska
oprema, ~etiri hale software, jedna hala kompletna re{enja, ~etiri
hale hardware. Da bih kako tako predo~io koliko je INVEX, kao
~etvorogodi{njak, porastao "moram da ka`em" da je gospodin Bill
Clinton jo{ 28. juna pozdravio u svom proglasu INVEX kao najve}u
izlo`bu informacione tehnologije u Centralnoj i Isto~noj Evropi! I
da je tog prvog dana na Microsoftovom {tandu, li~no i personalno,
~ika Bill Gejts odr`ao poprili~no dug govor.
U{av{i u prvu halu trebalo se odlu~iti na koju stranu da krenemo.
Oko nas su gomile proizvo|a~a ku}i{ta, UPS-ova, monitora svih
mogu}ih firmi, sistema za arhiviranje sa mikrofilmom, sa
CD-ovima.... Posle prolaska samo kroz deo hale B ve} smo bili
naoru`ani gomilom materijala. Komunikacja nije problem jer na
svakom {tandu se nalazi najmanje jedan ljubazni slu`benik-ca koji
dobro govori danas apsolutno standardni engleski.
Kao {to sam ve} pomenuo hale po sadr`aju nisu strogo podeljene (a i
dali je mogu}e?) i izme|u {tandova sa hardverom i bazama podataka,
nalazimo dilera STRIM-a 100 za ^e{ku, ina~e izuzetnog CAD/CAM/CAE
paketa, koji mi detaljno, koliko god je mogu}e uz pomo} ljubaznog
demonstratora testiramo. Apple je, po mom utisku, u velikoj ofanzivi.
Power PC se nalazi izuzetno ~esto, na mnogim {tandovima Apple je
predstavio i novu seriju laptopova.
Veli~ina {tandova zavisi od hale do hale, 40-100 m2 u ve}ini hala,
osim hale D "Kompletna Re{enja", gde su giganti kao Digital, IBM,
Simens, Nixdorf, HP, Oracle, Microsys, izgradili ~itave
konstrukcije na dva tri nivoa. Mada je i u drugim halama bilo je
zaista lepih i velikih {tandova, ali zamislite, samo na jednom
nivou!
Borland i Microsoft su svoje pakete nudili veoma povoljno i
prire|ivali brojne prezentacije najnovijih softverskih paketa, tj.
to su radili njihovi mnogobrojni dileri. Na velikom (ali ne i
najve}em!) {tandu Misrosofta vrtele su se videoprezentacije i
`eljno o~ekivao dolazak ~ika Bill Gejtsa i sve to je bilo pra}eno
porili~nom gu`vom. Taman kad smo se umorili vuku}i veliku koli~inu
materijala i svratili na ~uvene kobasice i jo{ ~uvenije Plzensko
pivo, Bill Geits je burno najavljen odr`ao govor koji se prenosio
preko razglasa po celom sajmi{tu. Tako smo uz izvrsno pivo slu{ali
o tome kako ~ika Bill vidi dalji razvoj Microsofta, dalji razvoj
multimedije, globalnu strategiju Microsofta itd. Kasnije smo
videli da je u publikaciji, koja je iza{la slede}eg dana,
objavljena i slika ~ika Bila, kako izlazi iz aviona propra}ena
odgovaraju}im tekstom. Uop{te dolasku Bila Gejtsa je pridat veliki
zna~aj {to jedan vizionar kao on i zaslu`uje.
Ono {to je po meni na sajmu bio trend je ekspanzija GIS-a
(geografskih informacionih sistema). Tog softwera je bilo zaista u
velikom broju, od raznih proizvo|a~a, doma}ih i stranih i vrteo se
na svim mogu}im platformama. I zaista je izuzetno upotrebljiv.
Testirali smo veoma detaljno dva od njih i bili izuzetno
zadovoljni.
Toshiba je predstavila svoje izuzetne laptopove na kojima je
multimedija ve} standard, a na tom polju je i Apple odu{evio sa
svojim desktop laptopom i softversko-hardverskim pick and go
sistemom za brzo va|enje laptopa. Zaista jako prakti~na stvar i to
jo{ sastavni deo operativnog sistema. Compaq je imao sli~nu ma{inu
ali bez navedene mogu}nosti.
Hala koja nas je impresionirala je bila ona ispred koje je stajala
tabla CAD. Te{ko je, u zaista sa`etom obliku, nabrojati ~ega tu sve
nije bilo. Mo`da bi lak{e bilo re}i ~ega nije bilo. Sama hala je
ve}a od kompletnog sajma informatike u Beogradu. Uz podatak da je
IBM sa svojom izvanrednom CATIOM bio u hali "Kompletna Re{enja" i
da je Digital na svom "standu" u istoj hali imao deo posve}en
CAD/CAM/CAE aplikacijama koje se vrtele na Alficama onda vam je sve
jasno. Ovde se o~igledno poklanja velika pa`nja CAD-u i postoji
isto tako veliko interesovanje za njega . To je za doskora{nju
veliku prazninu koja je vladala na tom polju i razumljivo. Od ljudi
koji prestavljaju Matra Data Vision (Euclid) saznali smo da, do pre
nekoliko godina, u [kodi u Mladoj Boleslavi nije bilo ni jedne
radne stanice a sada ih ima na desetine i to sa software Control
Date (ICEM) i Euclidovim Optrisom.
No da nastavimo, na ulazu u halu odmah smo "naleteli" na veliki
{tand Autodeska gde smo pored raznih PC-ija i Silicon Graphic
Irisa, na kojim su se vrteli Designer i Auto Surf, zatekli i jedan
PC rezervisan za prezentaciju `eljno o~ekivanog Auto CAD R13 {to me
je moram priznati ba{ obradovalo. Kasnije u zakazano vreme kada smo
do{li na prezentaciju razo~arali smo se jer je Autodesk predstavio
samo korisni~ki interfejs nalik CorelDraw, {to ipak i nije tako
lo{e. Kada dovedemo mi{a do nekog menija pojavi se mali kvadrati}
sa kratkim opisom funkcije. Ima nekoliko toolboksova po ekranu i
jo{ dosta korisnih sitnica. Kada sam slede}i dan detaljno razgledao
novosti iz Autodesk-a re~eno mi je da korini~ki interfejs nije jo{
"izbru{en", da je malo sporiji i da od manufacturing modula
(AutoCAD Manufacturig Expert) za sada nema ni{ta. Autodesk je
sigurno hteo da odr`ava tenziju i ni{ta vi{e.
Genius je imao veliki {tand gde je prestavljen njihov zaista
izuzetan dodatak AutoCad-u za parametarsko modeliranje, paket za
modeliranje sve do modula za konstruisanje alata za brizganje
plastike. Ugra|ena je podr{ka svim mogu}im standardima (niste
valjda o~ekivali i JUS-u).
I ^esi su se potrudili i na {tandu odmah do Geniusa su ponudili
svoj zaista dobar paket sli~ne namene Profi 5.2, po prihvatljivoj
ceni i podr{kom raznim standardima i mnogim drugim mogu}nostima.
Na sajmu Auto CAD se uglavnom vrteo na razroraznim PC-ima i Iris
Silicon Graphics radnim stanicama, koje me nisu ba{ ode{evile
brzinom. Me{iranje poznatog crte`a Engine potrajalo je oho-ho dugo
na Irisu sa 64MB Rama. Za{ta ipak nije kriv Silicon Graphics nego
software jer smo videli i bolja re{enja na drugim paketima. Kad sam
ve} pomenuo Silicon Graphics, on je najrasprosranjenija Unix
platforma u oblasti CAD-a, ja mislim zbog zaista brze grafike.
Bio je prisutran i glavni konkurent, danas neprikosnovenom,
AutoCAD-u, Microstation verzija 5. Program koji je mnogo bolji od
na{eg ljubimca ACAD-a, koji je jo{ pre nekoliko godina ponudio
NURBS modeliranje. Program sadr`i modul koji omogu}ava odli~nu
vizuelizaciju i animaciju koji se vrti od DOS-a, Meka, Windowsa,
WindowsNT, do UNIX-a i ima izuzetno lep korisni~ki interfejs. [to
je najlep{e od svega bez ikakvih problema radi u formatima DWG i
DXF i to stvarno radi (isprobano), plus je jeftiniji od ACAD-a a u
pricipu predstavlja ACAD plus Dizajner plus AutoSurf plus 3D
Studio. Ali ne pobe|uju uvek najbolji!
STRIM 100 je ispunio sve na{e zahteve, uostalom program ima oko
sedamdeset modula. Da ste samo videli kako lepo simulira hla|enje
ranih brizganih modela po va|enju iz kalupa. Simulira livenje i
mnoge druge stvari i to sve kao deo paketa.
Jo{ jedan francuski proizvod je pokazao svoju izuzetnu vrednost, to
je ve} pomenuti Euclid koji ima izuzetno jednostavno modeliranje,
izuzetan CAM modul. Ta~ka na i je bio modul OPTRIS, razvijen u
saradnji sa TOYOTOM, koji simulira, prora~unava i animira
izvla~enje velikih komada lima. Izuzetan alat kod dizajniranja
velikih preserskih alata bez kojih nema auto industrije. OPTRIS
poma`e kod odre|ivanja broja ciklusa potrebnog da bi se veoma
slo`eni oblici karoserija automobila izvukli i to bez gre{ke {to
veoma ubrzava proizvodnju alata jer se elemini{u gre{ke. Prednost
otklanjanja tih gre{aka vidimo, malo na na{im a vi{e na inostranim
putevima, po veoma brzom pojavljivanju novih modela automobila.
OPTRIS ^esi koriste u [kodi i u avio industriji. Firma koja je
prestavila Euclida je uradila i dobar deo alata za novu [kodu,
naslednika Favorita (Felacia), gde je Euclid pokazao vrednost
svojeg CAM modula u vo|enju glava za glodanje (T-tool) na peto-
osnim glodalicama. Ina~e novi model [kode je gotov i po {tampi,
prezentacija bi trebalo da bude do kraja ove godine. Ista firma je
koriste}i veoma mo}an paket Alias dizajnirala i novi automobil
[kode, koji bi po njihovoj pri~i trebalo da bude u klasi Pasata.
Naime [koda sledi politiku Seata, tako|e ogranka Wolksvagena. Ina~e
Alias je zaista izuzetan paket i u pravim rukama zaista obezbe|uje
fantasti~ne rezultate. Koristi se za kako oni ka`u primarni dizajn
naro~ito automobilskih karoserija.
Intergraph je bio predstavljen sa serijom svojih radnih stanica.
Najve}u pa`nju su privla~ile TD4 i TD5 koje nisu naja~e ali su
zasnovane na dva Pentijuma na 100MHz i zaista za svoju cenu su
izuzetno brze. Ja sam istestirao Microstation na jednoj takvoj
ma{ini i lepo se vrti. Tu je normalno bio i Intergrafov adut EMS
veliki CAD/CAM/CAE sistem koji je karakteristi~an jer se obi~no
izvr{ava na dva ekrana na karakteristi~nim Intergrafovim radnim
stanicama. Ina~e EMS je odli~an sistem sa veoma dobrom
vizelizacijom i odli~nim modelarom. Jedino mi nije jasno kod
Intergrapa dizajn njihovih monitora. Pomalo je arhai~an, li~e na
stare Ei televizore. Ina~e monitori su odli~ni i nude ih u
veli~inama od sedamnaest pa do ~ak dvadeset sedam in~a {to nije ba{
tako ~esto.
Normalno SDRC je bio tu sa svojim IDEAS-om za koji nudi ~ak
sedamdeset modula za najraznovrsnije primene.
Ipak i pored UNIGRAPHISA McDonald Douglasovog tako|e izuzetnog
CAD/CAM/CAE paketa, mene je najvi{e interesovao najmla|i ~lan male
grupe velikih CAD sistema koji je postavio op{te prihva}eni trend
parametarskog modeliranja Pro/Engineer. Kroz mnogobrojna
demostriranja i testiranja uverio sam se u lako}u modeliranja
odli~no automatsko a`uriranje modela, tehni~kog crte`a, alata za
livenje tog modela. Parametarsko modeliranje je na njemu, kako da
ka`em, jednostavno i izuzetno inteligetno. To smo videli na
modeliranju plasti~nog odlivka ku}i{ta ru~ne el. bu{ilice, gde se
jednostavnim zadavanjem jedne kote ru~ka tog ku}i{ta pomerala, ali
i {upljine i otvori su se zaista neverovatno "inteligentno"
prilago|avali promeni koja je odmah bila vidljiva i na crte`u i
zatim i na kalupu za livenje modela i na putanjama alata za
glodanje tog kalupa. Ali moram da napomenem da neko ne bi pomislio
da je sve tako lepo i idealno taj isti Pro/Engineer ima malo lo{iji
CAM modul. Lo{e vodi peto-osne glodalice, pa se modeli ~esto
prebacuju na druge CAD/CAM programe, npr. Euclid ili Duct, {to sam
imao prilike da vidim.
Idealnog paketa jednostavno nema, svaki ima neku slabu ili jaku
ta~ku ili ako je ba{ "mnogo dobar" onda je njegova cena problem.
Velike kompanije to itekako znaju pa imaju obi~no dva ili vi{e
sistema u svojim biroima. I da neko ne bi dizao u nebesa UNIX radne
stanice tu su problemi identi~ni kao i kod mnogobrojne armije PC
korisnika. Vi{e puta sam imao tu sre}u da na "tako ~uvenim" alfama
neke operacije i te kako potraju i da disk krcka kao i na PC-ju pa
i da sistem padne zbog punog diska. Zato treba da se radujemo {to
utakmica izme|u mnogih procesora i operativnih sistema i te kako
traje.
Od pristupa~nijih paketa isticao se DUCT, jedan zaista lep CAD/CAM
paket, sa veoma jakim CAM modulom za koji ni najslo`eniji oblici ne
prestavljaju problem.
A tu je bio i ArtCAM koji bi se jednostavno po meni svrstao u
"CAM-CorelDraw". Program koji jednostavno postavlja nove standarde.
Imao sam prilike da u jednoj alatnici vidim ArtCAM u dejstvu tj.
obratke koji su ura|eni na njemu i zaista je impresivno. DUCT i
ArtCAM su programi iz iste ku}e i me|usobno odli~no sara|uju.
Cimatron (biv{i MultiCAD)je bio prestavljen u verziji 6.2 i vrteo
se od DOS platformi, WindowsNT-a do UNIX-a po principu koliko para
toliko muzike. Solidan program sa ne tako dobrim CAM modulom kao
DUCT ali veoma upotrebljiv. Od ljubaznih demonstratora smo saznali
da je jedan Cimatron kupljen u Sloveniji, tek toliko da znamo.
Ina~e Cimatron se veoma lako mo`e prilagoditi potrebama korisnika
po potebi izuzetno lako pro{irivati i povezivati sa raznim CAD
programima od AutoCAD-a pa na dalje.
Na {tandu Digitala se nalazio Computervision ~uveni CAD/CAM
program, koji se standardno dobar iako se vrteo na alfi sa malo
slabijom grafikom.
Na CAE terenu su se isticali ADAMS 7.1 jedan zaista
odli~an program velikih mogu}nosti, pa NASTRAN lider na terenu
kona~nih elemenata, Cosmos koji je odli~no integrisan u AutoCAD i
Pro/Engineer.
Za probleme prilikom brizganja plastike i sli~nih stvari bio je
prestavljen zaista dobar MoldFlow sa kojim izbegavamo mnoge
neprijatne stvari koje i te kako zagor~avaju `ivot proizvo|a~ima
alata za brizganu plastiku.
Sve u svemu nekoliko dana koliko traje sajam, jednostavno su premalo
za sajam ove veli~ine, ali sasvim dovoljno za sticanje op{teg utiska
i koliko toliko sagledavanja pravca razvoja. Za mene je INVEX
predstavljao jedno veliko osve`enje, jer sam bio u prilici da mnoge
stvari li~no proverim i da pored stanja kod nas, koje je takvo
kakvo je, budem u toku sa de{avanjima na tr`i{tu.
Zato se nadam da }e INVEX kao petogodi{njak biti jo{ bolji i ve}i.

AutoCAD Network Installation
Ken Billing
Companies are networking every application imaginable these days,
but controversy still surrounds networking the AutoCAD program.
People who have heard of or experienced poor installations help
fuel the controversy by discouraging others from installing
AutoCAD on their file servers. I wish I had a dollar for every
AutoCAD network I've seen that has been incorrectly set up.
Part of this problem is with AutoCAD itself. AutoCAD is a very
complex and large application that makes tremendous demands on
system resources, including disk, memory, processor, video, and
I/O. Because AutoCAD is so configurable, there are numerous ways
to tune its performance, many of which should be employed when
installing the software on a network file server. Conditions
exist in a network configuration that greatly impact program
loading time, response time, and functionality that aren't
applicable in a standalone environment. It is the quality of
these factors that creates network horror stories.
To properly install and configure AutoCAD, you should use the
following guidelines. Space doesn't permit me to delve into network
specific parameters, file permissions, or related areas, such as
network plotting or drawing vault organization in this issue. But
if you follow these steps, you will at least end up with the
program executing as quickly as possible. Your mileage will vary,
depending on your network operating system, file server
configuration, workstation configurations, and other factors.
Step 1: Begin by logging onto the network with system administrator
privileges, and decide where in your directory structure you want
to install the software. Keep in mind that you will need to tailor
your users' file privileges in the directory structure that the
AutoCAD installation program will create. Make a directory to store
the AutoCAD executables, such as ACAD12. Then create shareable
subdirectories below ACAD12 that the installation program will not
create. One directory is necessary to hold the AutoCAD password
file if you elect to make the executable directory read-only. Name
this directory something like Acadpwd. Make another directory to
hold plot spool files named Spfiles.
Step 2: Launch the Install utility from your distribution
diskettes. Complete the personalization information, select the
installation options you desire, and specify the installation
directory that you created in the last step. Let the installation
program copy its files to your file server's hard disk. Up to this
point, nothing you have done will affect AutoCAD's performance.
Step 3: Run the cfigphar utility, which resides in your AutoCAD
executable directory. You only need to perform this step once after
installing the program files. Running this utility will modify the
AutoCAD executable's Virtual Memory Manager (VMM) to direct virtual
memory files to the workstations' local hard disks, rather than to
the file server (the default). With cfigphar, you want to modify
both the -swapdir and -nopagexp settings.
For the -swapdir setting, enter a directory name-c:Đacadnet, for
example-that will exist on every networked AutoCAD user's hard disk
to hold the VMM swap files along with others you will specify
later. Without this setting, AutoCAD will attempt to create virtual
memory page files in the root directory of the drive where the
program resides (the root of the file server hard disk), which is
typically off limits to user files. The network traffic caused by
the frequent writing and reading of these files (possibly several
per user) is the largest contributing factor to slow AutoCAD
network performance. Redirecting these files to the user's hard
disk causes this function to be equivalent to a standalone
installation. The local swap file directory must exist on the local
hard disk before executing AutoCAD or an error will occur.
Set the -nopagexp switch to On. This switch forces AutoCAD to
read executable code pages from the ACAD.EXE file on the file
server and to write unused pages to the swap file located in the
previous step. By default, AutoCAD discards unused pages and
rereads them as needed from the server, adding to network traffic.
Setting this switch further restricts network traffic to the local
hard disk and improves response.
Before you finish with cfigphar, also be sure that the -demload
switch is set, which is the default. Demand loading causes AutoCAD
to only read as much of the executable as necessary to initialize
the drawing editor and to defer loading other portions until needed
by various commands. As you exit cfigphar, have the utility create
CONF386.BAT when it prompts you. Run the batch file once to make
your modifications permanent. See Appendix E of the AutoCAD
Installation and Performance Guide for more information on these
settings.
Step 4: Modify the ACAD386.BAT file to reflect network and local
drive locations. The Install program will create
environment-variable settings that assume all file locations will
be on the server. Change the acadcfg environment variable to point
to the local AutoCAD directory you created in the Step 3,
c:Đacadnet. When you first configure AutoCAD from each workstation,
the ACAD.CFG file will be placed here. This placement allows each
user to have individual peripheral devices and preferences. Also
add the Acadnet directory to the ACAD environment variable path if
you want AutoCAD to search there for local menu and other support
files such as temporary blocks. Add an acadplcmd variable setting
if you will be using the Autospool mechanism (which I highly
recommend doing). Move the ACAD386.BAT file to a public directory,
which will be on each users' DOS path once they have logged in, or
leave the file in the AutoCAD directory and add the directory to
the DOS path. Place ADI driver variable settings such as dspadi and
dgpadi in each user's AUTOEXEC.BAT file as necessary. ACAD386.BAT
should now be applicable to every networked AutoCAD workstation.
Step 5: Configure the first workstation. First, make sure that the
CONFIG.SYS contains a Buffers statement of at least 60. Reboot the
workstation and log on to the network. Invoke the ACAD386 file to
launch AutoCAD for the first time. If you receive an "out of
environment space" error message, add a Shell statement to enlarge
the memory allocation. See your DOS documentation or the
Installation and Performance guide for more information. AutoCAD
should report that it has not yet been configured and will
automatically begin the hardware configuration routine. Specify the
correct hardware settings, then continue when prompted to enter a
default login name for AutoCAD (not your network login). This name
will be used in messages to other users attempting to open files
locked by this workstation. Enter a period if the workstation will
be used by several persons.
You will be prompted next for your AutoCAD server authorization
information. This step should also be performed only once. First,
enter the number of licenses you purchased as the maximum number of
users. When prompted if you would like to run the executable from a
read-only directory, respond "yes." When prompted for a directory
for server temporary files, enter the Acadpwd directory path from
Step 1. Enter a password to protect the server authorization when
prompted in this option only under the strictest security
conditions. Lastly, enter your authorization code number when
prompted.
The configuration information you enter up to this point is the
bare minimum AutoCAD needs to run. Next, you will begin to tune
AutoCAD's performance and functionality specifically for a network.
Begin by selecting main menu Option 8 to set the operating
parameters necessary for networking.
Step 6: Enter the plot file named Autospool in Option 3 of the
operating parameters to enable automatic network queuing. In
Option 4, enter the path to your spool file directory, Spfiles,
from Step 1. Select Option 5 and enter the local Acadnet directory
to locate temporary files. These temporary files are different from
the swap files created by VMM and managed by the settings in Step
3. Instead, this setting determines where AutoCAD's drawing data
manager places files. Use Option 6 to specify a network node name.
Use the person's initials who will normally operate the workstation
or a unique network node number up to three digits long. Set the
Acadnet directory path in Option 7 to locate the automatic save
file with the other temporary files. Reuse the default file name,
AUTO.SV$. Option 11 is for the login name you entered in Step 5.
You must enter a unique name each time you configure a new
workstation.
Step 7: Once fully configured, the AutoCAD drawing editory should
appear. Shell to DOS to make sure that the VMM files are actually
being created in the local Acadnet directory. These are the files
with a random alphanumeric name, one without an extension and one
with the extension SWR. As an editing session progresses, drawing
page files and scratch files with the extensions AC$, $AC, and PG*
may also appear in this directory periodically. When AutoCAD is not
running, none of these files should exist in the Acadnet directory
and may be safely deleted if found. Test for proper operation of
all configured hardware peripherals.
Step 8: Set up network-shared plotters and printers with
Autospool, port redirection, or a third-party spooler.
Step 9: Repeat Steps 5 through 7 for each additional workstation.
These steps are the minimum to complete an AutoCAD network
installation properly. Additional steps should be performed,
depending on your network operating system, to improve security,
flexibility, and convenience. The guidelines presented here should
help you get the best performance out of AutoCAD. To do any better
requires additional analysis, hardware, and network tuning.

ovoj poruci, da bi mogli svi da je vide (van Sezama).
A Look at AutoCAD Release 13
Changing the Way You For the Better
BY PETER SHEERIN
The first new release of AutoCAD in two years is on the way to a
dealer near you, but how will it affect the work you do? What
features could possibly be worth the hassle of upgrading?
New Entities and Features
One of the biggest limitations on new functionality in previous
releases has been the DWG format, a convoluted structure onto
which bits and pieces had been tacked at each new release. By
discarding the old structure (in its internal and file
representations), Autodesk has been able to add more than 20 new
entities to AutoCAD and has the ability to add new entities for
specific applications (such as AutoSurf).
If you are not using a drawing management program, you probably
have had a hard time finding the right drawing because drawing
names are never descriptive enough. The inclusion of a bit mapped
preview image of each drawing within the drawing file displayed
in the File Open dialog box eases this problem. It may not help
you find the specific drawing revision you are looking for, but
it provides all AutoCAD users with some sorely needed information
regardless if you are using a drawing management program, drawing
viewer, or nothing at all.
If you create drawings that have a great deal of text in them
(such as drawings that also serve as specifications), you have
probably made rude remarks about AutoCAD's anemic text-editing
abilities. Release 13 finally supports multiline text, complete
with word wrapping and character formatting, such as color,
stacked-fractions, bold, and italics, which will make it easier to
edit text within a drawing and import text from other sources.
The Windows version of Release 13 will also include a built-in
text editor designed specifically for dealing with the new
multiline text entity, and the DOS and Windows versions will
include a spell checker (contrary to our initial report).
One technology that has gotten much press lately is Object
Linking and Embedding (OLE), a standard developed by Microsoft
that allows for the creation and editing of compound documents.
For an example of the benefits of OLE for AutoCAD, consider this
situation: creating a table in a drawing that was a duplicate of
one that existed as a Lotus or Excel spreadsheet. In the past, it
was not only difficult to create a table with some semblance to
the original, but it was tedious to modify. Now, assuming you are
running the Windows version of AutoCAD and have an OLE server
application, you can simply copy that Excel spreadsheet to the
clipboard and paste it into your drawing. This process allows
you to have the chart appear as a normal part of the drawing that
displays and plots just as you would expect, but you edit the
table with Excel, not AutoCAD.
Dimensioning has also received a facelift. The old limitations of
dimension styles have been fixed, so you can now define a
dimension style that doesn't change its appearance based on the
current setting of a normal AutoCAD system variable. To solve
this problem, dimension variables help store the number of
decimal places displayed, zero suppression, unit format, and text
style. You can also create dimension style families so settings
can be specific to the type of dimension being created, whether
it is linear or angular. For the first time since their
introduction in Release 11, it appears that associative dimension
styles will finally be easier to use, which will help increase
the accuracy of your drawings.
If you are in one of the disciplines that typically uses fancy
linetypes to delineate specific features (such as different types
of fences or utility lines), you will welcome the ability to
create complex linetypes that include text strings or symbols.
While the symbols must be defined in shape files, making their
definition a bit on the complex side, this feature will be a
godsend to users who have struggled to manually create such
linetypes before. It will also lay the Framework for better
translations among other CAD packages, such as MicroStation,
which have had complex linetypes for years. Several third-party
utilities have provided this feature for quite some time; but by
the nature of AutoCAD's database, they could not be well
integrated into the drawing process.
One entity type that is sure to get a round of applause is the
new, mathematically correct splines and ellipses. No longer will
these entities have to be approximated by polylines consisting of
short lines that approximate the intended shape. This new feature
will let you edit splines and ellipses properly, including
operations that trim them. For instance, a trimmed ellipse now
becomes an elliptical arc, instead of just a bunch of connected
straight line segments. For those drawings that previously would
have used a lot of splined polylines, an additional benefit will
be a reduced file size because the spline entity can represent
the same shape with much less information.
New Editing Features
Interestingly, the addition of true ellipse and elliptical arc
entities was one of the missing puzzle pieces that prevented you
from exploding unequally scaled blocks. With those in place, you
can now explode any unequally scaled block, and be able to edit
the resulting entities.
Another benefit of the redesigned database is that it is now much
easier for programmers to add functionality. Without going into
the technical reasons, adding new behavior to existing entities
was a very complex and error-prone process, severely limiting the
capacity for enhancements. One of the resulting editing commands
is lengthen, which lets you change the length of any entity just
by selecting it and entering the new length at the keyboard or
with the cursor.
If you happened to read Programmer's Toolbox by Bill Kramer in
September ("Entity Handles and Extended Data," p.121), he
presented a sample AutoLISP program that could group multiple
entities together for certain editing operations, without having
to define them as a block. AutoCAD now has this capability
built-in, with a much more robust interface and feature set. The
group command lets you save named groups of entities that then
behave as one larger, complex entity, while still allowing you to
toggle back to the normal editing method when necessary.
If you are constantly using construction lines, AutoCAD now
provides bona-fide construction-line entities, which extend
infinitely in either direction (for xlines) or in one direction
only (for the ray entity), without changing the drawings'
extents. This addition seems simple, but in previous versions of
AutoCAD, it was not possible without performing lots of
trickery. Alas, there is nothing else magical about construction
lines; they will always plot unless you place them on a separate
layer and freeze it (or turn it off) before plotting-only to turn
it back on when you need them for editing.
Remember the flatland variable? It was used way back in Release
10 as a transition between the versions of AutoCAD that straddled
the change to a full 3D database. But when it was removed in the
next release, one important capability went with it: apparent
intersections. Even though it appeared that two lines intersected
on the screen, if they didn't truly touch each other in 3D space,
you could not snap to the projected intersection. For cases where
a drawing contained a mixture of true 3D entities and normal 2D
entities, this made many editing operations, such as trim and
extend, next-to-impossible. Release 13 restores that
functionality, without complicating things by bringing the
flatland variable back.
Similar complexities have been removed from the trim, fillet, and
extend commands. It used to be that only entities that were all
in the current UCS could be trimmed, filleted, and so on. Now,
the only requirement is that the operation is physically
possible-it doesn't matter what UCS or view you are in. And just
as you can now snap to an apparent intersection, you can extend
and trim entities to the point where they would meet another
entity, if only that entity extended far enough.
Perhaps the one new editing feature that will save you the most
time is the new hatching ability. The biggest difference is that
hatches are finally associative. If you move (or remove) one of
the existing hatch boundaries, it no longer means you have to
re-hatch an area or save the original hatch boundary for future
modifications. If you move any entity that was already selected
as a boundary for a given hatch, the hatch will automatically
regenerate itself, without forcing you to intervene at all.
Other time-savers
While I still haven't described all the new features (I haven't
mentioned the integrated support for solid-modeling entities or
the changes to the SQL interface, for instance), the ones I have
described should make life easier for almost all users. Upgrading
from one release to the next, from the DOS to the Windows
version, or from one bug-fix release to another can be extremely
time-consuming because it has traditionally required a complete
reconfiguration of AutoCAD, and manual updating of the menus, if
any had been modified.
With the clear focus on Windows as the preferred operating
platform of the future, it made sense to restructure the way
AutoCAD stores its configuration settings. They are now
maintained in a pure ASCII file, ACAD.INI, to comply with Windows
guidelines, even in the DOS version. What possible benefit could
this have to DOS users? It makes it easy to switch to the Windows
version, and it means that AutoCAD can now save many or all the
configuration settings from one update to the next because of the
extensible, stable nature of ASCII INI files.
Do you need to have both the DOS and Windows versions loaded on
your machine at the same time (the recent addition of a dual-use
license now allows this), but cringe at the thought of two large,
complete installations eating your disk space up in a flash? The
AutoCAD installation process now structures the directories in
such a way that shared support files can be shared and those that
can't be shared are kept separate. This setup also simplifies the
addition of either version if you initially only installed one of
the two.
With the new ability of partial menu loading, end-users and
thirdparty applications can tack-on their own menus to the
standard AutoCAD menu without having to duplicate and modify it.
With far fewer revisions to the standard AutoCAD menu needed,
upgrading and installing add-on products will become much simpler
in the future. Unfortunately, this new feature will only be
available in the Windows version.
There will be some downsides to the new release, however. The one
fundamental change that will ripple through the market will be
the new drawing format. Any product that reads or writes DWG
files on its own, without the use of AutoCAD, will have to be
updated before it will work with Release 13 files. This
stipulation will affect everything from simple file viewers to
competing CAD products, such as MicroStation, that boast of
AutoCAD file compatibility as one of their strengths. It may seem
as if Autodesk's plan was to cleverly modify the drawing format
just to make life difficult for these competitors, but the real
truth is that the old DWG format simply couldn't handle the new
Features that you will see in Release 13 and beyond. Holding on
to the old format would have limited the capability of AutoCAD to
a very significant degree.
Taken as a whole, the changes to Release 13 may not appear truly
radical to the naked eye. They will, however, provide significant
advantages to end users, system managers, and developers, while
helping to provide a solid base that will make it easier for
Autodesk to enhance the product in the future. Restructuring a
significant portion of the code has removed much of the
quirkiness of AutoCAD's behavior that has crept in over the
years. All of these changes in the evolution of AutoCAD may cause
a few problems during the transition period, but you will be
better off having left the old, tattered baggage behind.

Wishing On a List
In developing Release 13, Autodesk took the unusual step of going
to the users to find out what they really wanted in this product
that most of them use every day of their working lives. In
addition to focus groups, on-line exchanges, and road trips,
Autodesk relied on the Wish List maintained by the NAAUG
(National Association of Autodesk User Groups). As you can see
from the following lists, Autodesk hit a majority of the items,
though there will be users mightily disappointed at some of the
omissions. On the positive side, it's realistic to hope they will
be covered in the next release. It would behoove those readers
with pet peeves and nurtured wishes to put them in writing and
send them to Autodesk via CompuServe in the ACAD forum or through
your local user group.

NEW RELEASE STRATEGY
Along with its new products, Autodesk has developed new
strategies for getting those products into the hands of users.
Autodesk's goals include converting more users to Windows so they
will be potential customers for the raft of new Windows products
being planned (first among them is WorkCenter described by Craig
Sharp in "Autodesk WorkCenter,"October CADENCE, p.58),
encouraging the adoption of CD-Rom drives so that more
information can be delivered, more economically and, perhaps most
important of all compressing the upgrade cycle so that users move
to Release 13 within six to nine months rather than the more
usual nine to 12 months.
Autodesk has seriously jumped on the Windows bandwagon, but
the AutoCAD community has not greeted this news with universal
delight. The AutoCAD power user will always be suspicious about the
speed of AutoCAD on Windows. Autodesk believes that once it gets
users actually working with the product, the speed issue will be
less of o problem. Certainly, the Windows version of Release 13 is
glitter than the DOS version. Also, Autodesk has leveraged Windows
features such as the Clipboard to let users cut and paste between
the command line and the text editor, as well as DDE and OLE.
When it comes to convincing users AutoCAD product manager Maureen
Bragg is targeting the solid core she believes exists of people
who use AutoCAD in DOS but who use Windows for everything else.
These users are already committed to Windows, in theory and they
are just holding out for the performance they need to do their
job. To encourage users to make the change, Autodesk is allowing
multiple licenses for DOS Windows and Windows NT versions even
though, as of this writing, it doesn't look as if they will all
be released at the same time. Nevertheless AutoCAD Release 13
purchasers will get the Windows and DOS products whether they ask
for both or not. Because the DOS version is shipping first, users
who call and get an authorization code will get AutoCAD for
Windows when it's released. In the case of NT, Autodesk will
make it available to people who need it with a certificate.
Remember the Release 12 rollout? It was quite a different story
when users were forced to make a choice between Windows and DOS.
Most of them chose DOS.
Another technology Autodesk intends to take full advantage of is
CD-ROM. For software developers, CD-ROM represents a very
economical delivery-system option. There's a lot of product
packed into an AutoCAD box, and Autodesk is now packing a lot of
products. In addition it's including much more documentation
on-line and product demos.
Autodesk's commitment to CD ROM technology is also evident in its
new strategy towards support. The Support Desk, from Autodesk can
be purchased by dealers as an aid in fielding user calls for
support. Using a search mechanism that lets users query according
to a broad problem and then narrow it down to specifics should
ease the online life of many dealers struggling to offer support
to AutoCAD users on a small-business budget. However, some
attendees at CAD Camp, a dealer and developer sales conference
sponsored by Autodesk in the late summer, found the interface a
little cumbersome.
One of Autodesk,s primary concerns is the typically longer
upgrade cycle for AutoCAD compared to most software products.
Although most people upgrade their software within six to nine
months, AutoCAD users take from nine to 12 months to make the
change. Autodesk product rnanager Maureen Bragg acknowledges that
AutoCAD users are slower to upgrade because they have so much
riding on their software, but she'd like to accelerate the
process. To that end, Autodesk announced the upgrade pricing
($495 for Release 12 users and $695 for earlier versions). As an
incentive to buying a CD player, there will also be an additional
$100 discount for users who opt for the CD version before January
1995. (More inducement comes in the CD list price for Release 13,
which is the same as Release 12 at $3750, but $3995 for a
floppy-disk only package).
The faster users get on Release 13 and acquire CDs, the sooner
they may adopt Windows and start buying all the other products
Autodesk developers are busily working on. Perhaps, though, the
strongest argument in favor of Windows and AutoCAD is that of
compatibility and integration. If everyone is working on Windows
and even Windows NT, then it will be much easier to develop
products that work together. It should be noted that UNIX vendors
are no more thrilled with this strategy than are die hard DOS
users. As for the other platforms Autodesk has pledged to
support, so far the company has only committed to HP-UX,
SunSolaris, IBM AIX, SGI Irix, and an NT version for the DEC
Alpha. Macintosh? Don't hold your breath. There simply have not
been enough Macintosh versions of AutoCAD sold to spark
Autodesk's-and Apple's-interest.
Roadshow calendar
Autodesk is faking Release 13 on the road this month to give
users a first look at the product. Not only is Release 13 on the
agenda, but vertical presentations will reflect Autodesk's new
strategy of targeting individual markets. Add-on products from
Autodesk and third-party developers in the AEC, Process and
Power, GIS, and MCAD markets will be highlighted. However, not al
road shows will feature presentations from all the vertical
markets. As we go to press, the schedule looks something like
this:
Nov. 7 Nov. 8 g Nov. 9 Nov. 10 Nov. 11
Long Beach Phoenix Denver Seattle Sunnyvale
Dallas Houston Kansas City St.Louis New Orleans
Milwaukee Minneapolis Detroit Cincinnati Cleveland
Boston West Hartford Parsipanny Bethesda Pittsburgh
Charlotte Raleigh Orlando Birmingham Miami

sprovoditi sledeci postupak.
1. Kandidati koji donose rad moraju popuniti prijavni list, ako to nisu
ucinili do tog trenutka. Prilikom predaja prijavnog lista moraju omo-
guciti clanu komisije da proveri njihove licne podatke odnosno da ima
uvid u podatke u licnoj karti. U slucaju da je kandidat ispunio prij-
avni list clan komisije mora proveriti da li se ovi podaci slazu sa
podacima lica koje podnosi dokumentaciju na uvid.U tu svrhu se prija-
vni listovi clanova CADUA koji nisu regulisali svoj status predajom
radova na uvid i njihovim prihvatanjem, nose na sastanke u Prote Mat-
eje 36, subotom ili na neko drugo mesto ako dodje do promena.
2. Rad koji se predaje prijemnoj komisiji mora biti u saglasnosti sa usl-
ovima koje je propisala Prijemna komisija CADUA na osnovu odluke Skup-
stine i naloga Predsednistva CADUA i koji su dati u prilogu ovog teks-

3. Prilikom prijema predstavnik komisije izdaje kandidatu kopiju potvrde
o primljenoj dokumentaciji. U potvrdi mora biti navedena tacna specif-
ikacija preuzetog materijala. Potvrda mora biti overena pecatom CADUA
i potpisom ovlascenog clana komisije. Prilikom povracaja materijala
kandidatu uporedjuje se sadrzaj originala potvrde (trajno vlasnistvo
CADUA) sa dokumentacijom koja se vraca kandidatu. U slucaju da nije
izvrsen kompletan povracaj dokumentacije na potvrdama (original i kop-
ija) precrtavaju se one pozicije ciji je povracaj izvrsen. Tacnost se
dokumentuje potpisom obe strane (kandidata i predstavnika komisije) i
kandidatu ostaje njegov primerak (kopija) potvrde. U slucaju da je iz-
vrsen kompletan povracaj preuzete dokumntacije kopiju potvrde unistava
predstavnik komisije a na originalu se upisuje da je povracaj izvrsen
o cemu treba da svedoce potpisi clana komisije i kandidata. U slucaju
da kandidat izgubi kopiju potvrde, posle uvida u licne isprave kandid-
ata i uporedjivanja sa licnim podacima kandidata kojima raspolaze kom-
isija, a nalaze se u prijavnom listu predstavnik komisije pravi zapis-
nik o predaji dokumentacije o cemu svedoce potpisi obe strane.

objekta itd ..
- crtezi pre predaje komisiji trebaju da budu ocisceni od neiskorisce-
nih blokova, layer-a, Dim-style-ova itd ..
Principi organizacije crteza na koje komisija obraca posebnu paznju:
a.1) Rad sa LAYER-ima
- layere nazivati imenima (na primer: beton, opeka, srafura, kote, op-
is ....), ne brojevima ili karakterima (pogresna imena Layer-a 1,2,
3,4,5,6,7,8,9,a,b,c,..). Dobra varijante su imena sa kombinacijom
broj_tekst ili tekst_broj
- layere praviti ne po debljinama pera, vec po vrsti sklopova/entiteta
koji se na njima nalaze. Na primer, za arh. podlogu/osnovu, zgodno je
odvojiti layere po materijalima (beton, opeka,izolacija i slicno).
Dalje, odvojen layer se pravi za linije u izgledu (parapeti, stepen-
ista, pragovi) kao i nevidljive linije koje se prikazuju isprekidano
(nadvratne i natprozorne grede u planu pozicija i slicno).
- entiteti u crtezu UVEK imaju linetype i color BYLAYER !!!!
- svaki layer treba da bude smislena celina za sebe. Na primer, konst-
ruktivne ose, betonski zidovi, zidovi od opeke, horizontalni razvod,
uticnice, prekidaci, radijatori, sanitarije.... Ne treba bezati od
mnogo layera, vec praviti sistem u kome se TACNO zna gde je sta.
- layer 0 OSTAVITI PRAZAN !
- praviti odvojene layer-e za pojedinu srafuru/e, kote (po nivoima
slozenosti recimo osnovne, detaljne ...) i tekst/ove.
- kada se radi o srafuri pozeljno je na layer-u DEFPOINTS ili POMOC
zatvorenom polilinijom uokviriti zeljene delove koji treba da se sr-
afiraju jer se selektovanjem polilinije najmanje vremena gubi za sr-
afiranje.
- sve pomocne linije crtati na layeru DEFPOINTS koji se ne plotuje ili
ako to nije dovoljno dodatno na layeru POMOC
a.2) Rad sa BLOCK-ovima
- uvek praviti block-ove kada se isti sklop entiteta pojavljuje nekoli-
ko puta u crtezu.
- Sve block-ove praviti na layer-u 0
- koristiti sopstvenu biblioteku block-ova ako je oformljena.
- koristiti XREF ako se ista grupa entiteta pojavljuje u nekoliko razl-
icitih crteza, a moguce su promene u samom crtezu koji treba da se
ucita kao XREF.
Posebno obratiti paznju na sledece greske:
- veliki broj duplih linija
- puno razlicitih stvari u jednom layer-u (opsti rusvaj na crtezu)
- ne koriscenje OSNAP-a,
- jedan layer sa raznobojnim entitetima (nepostovanje pravila by-layer,
by-linetype..)
- nepoznavanje osnovnih naredbi (Extend,Trim,Offset,Fillet,Break...)
- nepoznavanje DIM oblasti
- u slucaju da u vise lejera crta isti detalj u istoj boji i tipu lini-
je potrebno je da to u pomenutom *.TXT obrazlozi na adekvatan nacin
inace se to smatra dovoljnim razlogom za odbijanje rada.
a.3) Plotovanje
- dodeliti BOJE perima. Ako postoji tri pera (najcesci slucaj) ici ist-
im principom kojim ide i AutoCAD : pero 1 se pridruzuje boji 1+n, gde
je n=0+(ukupan broj pera). Znaci, boja 1, 4, 7, 10 ... su pero 1, bo-
ja 2, 5, 8, 11 su pero 2, boja 3, 6, 9, 12 su pero 3. Ova podela nije
primenljiva za tkz. "pljuckavce" koji emuliraju ploter tada je podelu
potrebno napraviti u zavisnosti od specifikacije printera.
b) Za radove koji su aplikacije uradjene nad nekim CAD programom
- kandidat mora najmanje sedam dana unapred komisiji dostaviti pisani
dokument u kome opisuje svoj rad (svrhu, metodu, postupke pri korisc-

- kandidat i clanovi komisije dogovaraju termin testiranja koji odgova-
ra obema stranama, posto komisija bude u stanju da obezbedi adekvatne
racunarske resurse

ije se mogu upoznati sa aplikacijom i isprobati je. Po pregledu se
deo diska na kome je bila aplikacija u prisustvu autora brise i cisti.
- ocenu nivoa primenljivosti odnosno tehnicke obrade davace clanovi ko-
misije koji ispunjavaju neke, ili sve, od sledecih uslova:

viru ciljne grupe/struke.
- nakon upoznavanja sa aplikacijom, demonstriranja od strane autora, is-
probavanja i razgovora sa autorom clanovi komisije ce u roku od sedam
dana dati pismeni izvestaj i svoje misljenje.
- pozitivno misljenje o prijemu se odnosi samo na sposobnosti autora da
ispuni minimalne uslove za prijem. Za testiranje softvera (aplikacije)
i davanje misljenja o njegovoj primenljivosti se sprovodi poseban pos-
tupak po posebnoj specifikaciji, o cemu se zainteresovani mogu naknad-
no obavestiti kod predstavnika CADUA.
Tekstualni prilog uz prijavu bi morao da sadrzi i sledece podatke:
1) Naziv paketa i broj tekuce verzije;
2) Ime i prezime autora ili grupe autora;

4) Kontakt adresa;
5) Pocetak rada (ovo je za komentar);
6) Verzija AutoCAD-a za koju je pravljena prva i tekuca verzija;
7) Potrebna optimalna i minimalna konfiguracija na kojoj radi,
hardverska i softverska;

zovanja podrske;
18) Stepen zavrsenosti i predvidjeni rok za konacnu verziju;
19) Orjentaciona cena paketa.
c) Za radove clanova koji se bave renderingom i animacijom

tretmanu sa svim ostalim kandidatima za prijem u CADUA
2) Preduslovi za prijem su ispunjen prijavni list i podnosenje radova na
uvid.
3) Radovi se podnose na uvid u hardcopy obliku, i jednom od bitmap formata
koje podrzava vecina rendering programa, znaci TGA, TIFF, JPG. Zbog
moguce velicine fajla, preporucuje se JPG format, u rezoluciji 640*480,
sa kompresijom od 75%, u True Color-u (16.7M boja).
Animacije se podnose na uvid na video kasetama. Animacije koje se dono-
se na disketama se primaju samo u FLC formatu, minimalne rezolucije
640*480. Radovi nize rezolucije nece biti razmatrani, jer zbog loseg
tehnickog kvaliteta nije moguc uvid u znanje autora. Jedina olaksavaju-
ca okolnost moze biti izricita pismena izjava narucioca posla da ne ze-
li rad u visoj rezoluciji. U tom slucaju komisija zadrzava pravo da od-
ustane od izjasnjavanja po pitanju kvaliteta rada.
4) Uz radove priloziti list sa kratkim opisom istih. Obavezno navesti koji
gotovi objekti su korisceni, u kom softveru je raden model koji je mat-
erijalizovan, kao i u koju svrhu je rad radjen (priprema za stampu, re-
klamni spot, istrazivanje autora ... ). Svi navedeni podaci se smatraju
poslovnom tajnom, nisu dostupni javnosti i sluze samo za rad prijemne
komisije CADUA u cilju tacne procene rada.
5) Prilikom ocenjivanja rada, posebnu paznju Prijemna komisija CADUA ce
obratiti na :
- upotrebu gotovih objekata iz dostupnih biblioteka
- primenu i dodeljivanje materijala
- izgled i definiciju senki
- refleksije, mapiranje i kadriranje
- u animacijama, postojanje senki i refleksija, glatkocu pokreta,
kao i bljeskanje i prelivanje boja
- upotrebu procesa (ako je rad uradjen u 3D Studiu)
6) Dostavljene radove CADUA vraca autoru na dogovorenom mestu i u dogovor-
eno vreme, a najranije 7 dana posle primitka istih. Na osnovu izricite
izjave autora, a na predlog Prijemne komisije, kopije radova se zadrza-
vaju u arhivi CADUA i sluze samo u svrhe medijske prezentacije rada cl-
anova, pri cemu se zadrzavaju originalna autorska prava.
7) Uz vracene radove autor ima pravo da zatrazi i dobije pismeno obrazloz-
enje to jest misljenje Prijemne komisije sa potpisima clanova.
Napomena: Ovi uslovi za prijem se primenjuju od 01.09.1994 godine.
Dalji rad u CADUA na na standardizaciji crteza i definisanju
potrebnih i minimalnih normi u radu sa CAD-om mogu dovesti do
promene ovih uslova o cemu ce kandidati za clanove biti na
vreme obavesteni.

Taking Apart Release 13
Zeroing In on Autodesk's Latest Release
B Y P E T E R S H E E R I N
Finally, Release 13 is making it out Autodesk's front door. For
this review, we've taken some of the major features and put a
magnifying glass on them. We have not gone into great detail on
the Windows version because, at press time, it was not ready for
review. The Windows version will have all of the features of
Release 13 for DOS, plus a few others, including OLE support,
enhanced menus, and a brand-new interface. Plenty of other new
enhancements may not require a whole section to describe but are
certainly worthy of mention.
One of the biggest changes in the DOS release is the inclusion of
a display-list driver in the box, just as has been the case with
Release 12 for Windows all along. The driver, licensed from
Vibrant Graphics, is basically the same as its low-end driver,
with the inclusion of an aerial-view (or bird's eye). Aside from
the enhanced speed and interface this setup provides, the driver
adds a feature certain to be cherished by all the single-screen
AutoCAD users: a graphics-based text window. No longer does doing
a flip screen (either manually or as a result of the LIST
command, for example) switch to the standard black text screen,
forcing the monitor to delay switch modes. Instead, the text
output is mapped to the graphics screen, eliminating yet one more
annoyance left over from the old AutoCAD.
The dialog-based help system that was introduced in Release 12
has been revamped and now functions very much like the Windows
help system. Hypertext links and pop-up definition boxes are
supported, along with a searchable index and navigation keys.
Of particular interest, the new help system has two features
that will be of use to all AutoCAD users. A comprehensive list
and description of what commands have been added, changed, or
removed between Release 12 and Release 13 will help make the
transition easier for users. The reference manual is split into
two parts, the User's Guide and the Command Reference. Autodesk
has included the full text of the Command Reference in the help
system, complete with hypertext links where appropriate. There
are no graphics, but this setup will reduce the need to refer
back to the paper manuals to learn about the less often used
commands.
Another new item on the driver front is an enhanced HP-GL/2
plotter driver from Hewlett Packard that provides many more
configuration options. This driver is basically the same one that
HP includes with its plotters, and it provides more control over
HP-GL/2 features, such as line cap ping and line joining
(beveled ends versus rounded, and so on), screened lines, raster
pattern fills, and an option to combine one rendering onto an
otherwise normal vector plot. Also, due to popular demand, the
included drivers finally support the HP DeskJet printers!
Support is specifically included for the 500, 500C, and 550C in
monochrome and color modes. The PostScript driver now supports
600dpi and adds the option to have either a <Ctrl-Z>, <Ctrl-D>
character, or both to the end of the output.
Among many of the small changes to AutoCAD that begin the
elimination of confusing behavior is a new method of entity
picking. If you have selected one entity that is coincident with
one or more other entities, it has not always been possible to
select the one you were actually after or even see that there was
more than one entity there in the first place. Now at the time
you select an entity, you can hold down the control key while
pressing the pick button to cycle through all the entities within
the aperture that you selected. Another fix along these lines is
the ability to purge the drawing of unused blocks, text styles,
and line types at any time-not just when the drawing is first
opened.
While Release 13 has many new features and enhancements, some
capabilities have disappeared. Freeplotting (the ability to
launch AutoCAD and plot without using up a network license),
which first appeared in Release 12, has now, disappeared, without
the functionality appearing elsewhere. The one solution to this
problem in the past was a "show demo" version of AutoCAD, which
could plot and edit but not save drawings. It was an inexpensive
product, but there is no guarantee that it will reappear. The
built-in IGES translator has also disappeared. Even though it
supported a very old version of the standard, but to get that
functionality, you have to purchase Autodesk's separate, $1200
IGES translator.
Despite all the information we've given you, there is a lot more
detail to go into later. Keep your eye on our regular columns for
more information about the inner workings of Release 13.
Text Enhancements
by Peter Sheerin
A big shortcoming of AutoCAD has been its lackluster support for
text-even though text is a an important part, and sometimes large
percentage, of your drawings. Previously, each line of text had
to be a separate entity. No word wrapping was performed, and
although paragraphs could be formed, they were not a picnic to
edit if the length of a line within a note changed. Release 13
adds of number of important enhancements that improve text
handling, but it is still lacking a few features that would make
it even easier.
A new entity, MTEXT, provides paragraph text. Now, on text entity
can span multiple lines and can be automatically word-wrapped at
a given location. In addition to standing on its own, an MTEXT
entity is used with the new associative dimension leader, so
leaders can now have multiline text.
The addition of a multiline text entity requires a new method of
input, beyond the simple command line. Here lies one of the
limitations. While the Windows version of Release 13 will include
a text editor specifically designed for the MTEXT entity, the DOS
version doesn't include such an editor and instead, relies on the
user to have a DOS text editor, shelling out from AutoCAD each
time an MTEXT entity is created or modified. This process is
cumbersome because that text editor may or may not have a
word-wrap function and certainly won't know what the specified
margins for a specific MTEXT entity were, even if it did. While
the Windows MTEXT editor provides buttons and check-boxes to
modify properties of individual words and characters (just like a
word processor), in the DOS version of AutoCAD, these settings
must be manually specified by embedding special formatting codes
in the text. Not providing an MTEXT editor in the DOS version was
a mistake and is one Autodesk should fix quickly.
Also, while AutoCAD now supports TrueType and Type 1 scaleable
fonts, its primary font architecture is still the old vector-
based SHX font. This setup means that while True Type and Type 1
fonts can theoretically have attributes, such as bolding and
italics applied to them, SHX fonts have no such capability and
Autodesk decided to make MTEXT editing less confusing by not
implementing those font attributes. You can, however, specify one
or more different fonts within each MTEXT entity. Because Type 1
fonts treat different styles as individual font files, you can
achieve the desired appearance with italic, bold, and bold-italic
versions of a given Type 1 font.
The allowed formatting includes stacked-fractions, overline,
underline, nonbreaking spaces, color, tracking, width, and
obliquing (an imitation of italics, but an incorrect one). Bold
and italics are available in a font change. It is also possible
to define a font-mapping file that provides two benefits. If you
are sending a drawing to another AutoCAD user who doesn't have
the same fonts as you, you can remap the fonts to different,
standard AutoCAD fonts. You may want to use this feature for
editing with standard AutoCAD SHX Fonts (fast!) but switch fonts
to filled Type 1 or TrueType (slow, but pretty) fonts easily and
painlessly when it's time to plot.
While this may not be of interest to most of our readers,
international AutoCAD users will appreciate the ability to
redefine which direction the text flows. For those languages of
the world that read from right to left, AutoCAD can now create
text in that direction. It also can handle all the complex and
numerous characters in foreign languages with its added support
for Unicode fonts.
And last, but certainly not least (it has consistently been at
the top of AutoCAD wish lists), DOS and Windows versions of
Release 13 include a spell-checker. This spell checker is
full-featured-similar to the one found in word processors, such
as Microsoft Word-and even includes user-defined dictionaries
(but no, not quite compatible with Word's dictionaries).

Dimensions:
Good News
and...
by John Gibb
It was with much anticipation that I dived into the new dimension
features in Release 13. I had heard that Autodesk took the wish
list seriously, and it had reworked dimensioning extensively. I
was not disappointed. Well, not much. As you can see from my
What's Hot? list, I do have one wish that was unfulfilled by this
new version.
No Associative to the Geometry
AutoCAD has had associative dimensions since early on in the
development of the software. Unfortunately, the dimensions are
associative only in the sense that they are aware of their own
definition entities and definition points (control points). They
have never been truly associative to the geometry that the
annotate. That is still the case, and it is unfortunate that true
associative dimensions have not been added. This complaint is
small compared to the many new features and new user interface.
New Dialog Boxes
The DDIM dialog box and its child dialog boxes have been totally
reworked. They are more intuitive for the various dimension
styles you create and for the new process of creating dimension
families.
The same dialog boxes you use to create a dimension style are
used for creating the family members of a dimension style. You
can simply pick the family type from the list of radio buttons
and then select the Geometry. . . , Format..., or Annotation. .
button to set up the dimension variables for that family
member.
While the child dialog boxes have been rearranged, their function
has not been changed. The new feature in the boxes is the
inclusion of image tiles that reflect the changes you make. You
can pick on the image tile and you will toggle through the
possibilities. Or, you might choose to use the radio but- tons or
pop-up list to make your choice.
Dimension families
This new concept makes it easier to create one dimension style
that can look like multiple dimension styles. Now each dimstyle
can have a separate setup for dimension types like linear,
radial, angular, diameter, ordinate, or leaders. If you have a
separate setup for linear dimensions in your style, AutoCAD
will automatically use the changes when you place a linear
dimension with that style.
Dimension Variable Overrides
Overrides are applied to individual dimensions in a dimstyle, and
the dimension will still reference the dimstyle it was created
with. No more UNNAMED dimstyle when you override a dimension.
Independent Dimension Units
Each dimstyle can now have its own units attached to it,
independent of the drawing units. You can also use the override
feature to assign different units to individual dimensions while
the dimension keeps its dimstyle.
Extensive Arrowhead Support
You can now have no arrowheads, open or closed, arrowheads,
rightangle, closed-filled, oblique, dot, origin indication, and
user-defined arrow heads. More basic choices means less hassle.
Nonlinear Leader Lines
You can now have curved leader lines using the format option for
leaders.
Geometric Dimensioning and Tolerancing
Mechanical Engineers and Drafters will be happy with the new
tolerance command. AutoCAD now has Geometric dimensioning and
tolerancing (GD&T) built into it. GD&T is an international
standard used by the mechanical disciplines to define geometric
constraints on any given design.

AVE Render Updates
by Craig Sharp
While the 3D modeling capabilities of Release 13 DOS will be a
welcome addition for people who find themselves building models
of their ideas, the ability to visualize those results in
impressive fashion is still left up to products such as
AutoVision, 3D Studio, and other third-party renderers. The
improvements made to AVE Render, important as they are, cannot be
termed exciting. The speed of rendering in Release 13 is most
definitely improved and is likely attributable to Rx ADS. Phong
shading has been added as well as spot lights and the interface
via dialog boxes is better thought out and more accessible. Most
improved is AutoCAD's ability to exchange files with other
Autodesk rendering products, which at least improves your ability
to create impressive renderings from external applications. The
relationship between AutoCAD and 3D Studio, AutoVision, and
Visual Link has been unified, and true material libraries in MLI
format are now supported in import and export fashion.
Even though not all of the effects of materials applications can
be viewed in AutoCAD, they will, at least, transport back and
forth between AutoCAD and 3D Studio or AutoVision using two new
commands, 3DSin and 3DSout. Materials created in 3D Studio that
have maps applied are imported by converting the map to a Targa
file, except for materials created using animation files that use
only the first frame of the animation or IPAS routines.
Furthermore, lights, meshes, materials, and cameras can be
retained, and a variety of color, material, and object creation
options are available. You can also select which objects will be
imported into AutoCAD. AutoCAD will import a 3D Studio file and
create layers based on how the model was created in 3D Studio,
naming the layers by the object's color, material, or object
name. You can also import everything to one AutoCAD layer if you
so desire. 3D Studio cameras are retained as views in AutoCAD,
and objects are assigned a color approximating their 3D Studio
color from AutoCAD's color palette. Ambient light loses any color
assigned in 3D Studio, omni lights become point lights, and
spotlights become spotlights. Finally, AutoCAD provides you with
the option of splitting 3DS objects that have more than one
material assigned to them. Exporting AutoCAD geometry to a 3DS
file provides many of the same features as importing the 3DS
file: adding the ability to split blocks or retain them as a 3DS
object, creation of 3DS smoothing groups, and automatic welding
of vertices.
The addition of Phong shading provides a more pleasing look to
the treatment of materials and color in AVE Render and is
necessary when using spotlights. Figure 1 shows a rendering that
includes standard point lights, materials with a variety of
ambient, specular, and roughness settings, and the addition of
the new spotlights. Unfortunately, setting the hot spot and
Falloff of the spotlight cone is not a dynamic process (you can't
visually adjust the size of the cone) and requires some rather
arcane guesswork to obtain the proper settings. Even more
disappointing is the fact that no form of shadow casting is
included with the spotlights.
Therefore, the final effect of the placement of the spotlights
for use in a more sophisticated rendering environment cannot be
visualized.
The Render menu is now placed under a Tools pull-down menu, which
is more appropriate for the frequency of use of AVE Render. Once
you trickle down to the desired render command, dialog boxes are
presented that place the rendering options more readily at hand
and in a less obscure fashion than those of Release 12. The
naming, selection, and application of materials from two dialog
boxes using a materials library is certainly a welcome
improvement and you can now assign materials by layer in addition
to Release 12's way o doing it by color and entity. Finally, you
can render directly to a file instead of first rendering to the
display and then saving the image to a file. If you own a
thirdparty rendering program, you will appreciate the additions
to AVE Render for Release 13. If you want AutoCAD to do your
renderings for you, you will be pleased with the increased speed,
improved interface, and improved display of color via Phong
shading but you will find yourself still waiting for a real
rendering environment.

Compatibility Concerns
by Ralph Grabowski
With ten programming interfaces, it would seem that AutoCAD is a
rich enough environment for developers. In Release 13, Autodesk
has created yet another applications programming interface (API)
it calls Rx. This API promises an even tighter integration of
third-party programs with AutoCAD.
Rx applications are like dynamic link libraries (DLL) under
Windows. A DLL is only loaded when the application requires it.
Then, the DLL loads automatically. Rx applications retain their
DLL status even when running under DOS. Smaller AutoCAD
developers are not happy that employing Rx required a 32MB
computer running Windows NT-even for DOS-based Rx applications.
At the time of this writing, Autodesk was still creating the new
API and did not expect to finalize it or the documentation until
after Release 13 ships.
The other significant change to programming Release 13 is the
ability to load menu fragments. Currently, to change a menu, an
entire MNU file must be loaded. Release 13 is able to load
portions of an MNU file, as required.
Command Compatibility
As you would expect, Release 13 has many new commands. What
developers might not expect is that a number of existing commands
have different names. This news is bad and good-bad because
AutoCAD veterans have to retrain their fingers, in some cases,
and good because Autodesk has integrated the appendix commands,
such as Dim:Hor and (xload "ASE") AseEraseTable, to make them
more like core-code commands.
If you customize AutoCAD in any way, you need to be aware of the
blatant and subtle changes to the command set. At the time of
this writing, the beta version of Release 13 contains more than
70 new and changed commands. The 33 new commands in Release 13
are:
3DSin, 3DSout, AcisIn, AcisOut, AmeConvert, BmpOut, CloseDwg,
CopyHist, DdColor, DdGroup, DdLtype, DdStyle, DdToolbars, Group,
HatchEdit, InsertObj, Lengthen, MenuLoad, MenuUnload, MlEdit,
MLine, MlStyle, MText, OleLinka, PasteSpec, Ray, Rx, SaveAsRl2,
Spell, SplinEdit, SysWindows, VIConv, XLine, and Xplode.
As is common in AutoCAD, many commands have additional options.
Some commands, such as InsertObj and OleLinks, are specific to
the Windows version of Release 13. Many of the commands with
changed names are external routines that Autodesk rewrote as Rx
programs. In some cases, Autodesk reduced the number of commands
required to use a feature. The most dramatic example is in ASE,
where just six commands replace 31. The dimension, AVE, ASE, and
AME commands have been renamed, as follows :
Renamed dimension commands:
DimAligned, DimAngular, DimBaseline, DimCenter, DimContinue,
DimDiamter, DimEdit, DimLinear, DimOrdinate, DimOverride,
DimRadius, DimTEdit, Leader, and Tolerance.
Renamed AVE commands:
DLight, MakePreview, PLight, and SLight.
Renamed ASE commands:
AseAdmin, AseExport, AseLinks, AseRows, AseRunRep, AseSqlEd.
AME commands have reappeared in AutoCAD as new entities:
Box, Cone, Cylinder, Extrude, Interfere, Intersect, MassProp,
Revolve, Section, Slice, Sphere, Subtract, Torus, Union, and
Wedge.
Other renamed commands:
One other existing command has been renamed:
bpoly is now boundary. Two existing commands have a pair of added
options. The chamfer command has the Trim and Method options
added; the osnap command has the new Insert and AppInt options.
File Compatibility
For the first 10 releases of AutoCAD, Autodesk made the DWG file
format incompatible with previous versions. In Release 11, John
Walker wrote DxfIx to convert R11 drawings to R10 via DXF. In
Release 12, the DWG format was not changed, allowing Release 11
to read R12 drawings.
With Release 13, the DWG file format has dramatically changed
again. However, for the first time, Autodesk includes a native
backward translator, the SaveAsRl2 command. The command saves the
current drawing in Release 12 format, converting or stripping out
incompatible Release 13 entities.
The internal IGES translator has been dropped from Release 13.
Because Autodesk had never bothered to upgrade the translator
from its rather ancient version 3.4 standard, this change isn't a
big deal; however, Autodesk's up-to-date version 5.2 IGES
translator is an additional $1,200.
The AME in Release 13 uses ACIS-based modeling, unlike the
PADL-based modeling used in the AME of Release 11 and 12. The new
AMEconvert command brings solid models created in earlier
versions of AME into Release 13. To read solid models created by
other ACIS-based modelers, Release 13 includes the new ACISin and
ACISout commands.
To tie AutoCAD more closely to 3D Studio, Autodesk had released
Visual Link. In Release 13, the optional software package is no
longer needed. The new 3DSin and 3DSout commands read and write
3D Studio files; the new VlConv command converts files created by
Visual Link.

Rx ADS:
Improving the speed!
by Bill Kramer
AutoCAD R13 introduces a new twist to the most powerful
customization tool available for this CAD engine, ADS. In brief,
Rx ADS changes the way AutoCAD and ADS-based applications
communicate with each other. The net result of the change is
greatly improved performance for ADS applications that
communicate with AutoCAD frequently. One way of viewing the
improvement is that Rx ADS streamlines the communications between
ADS and AutoCAD by eliminating the go between, which is AutoLISP
in this case. Traditional ADS programs communicate with AutoCAD
trough AutoLISP, which, although fast, had room improvement-
especially in the arena of entity and table manipulations within
the AutoCAD drawing database, and that is what Rx ADS addresses.
Rx ADS does not represent the quantum leap execution speed we
experienced when ADS first showed up as a tool for improving
AutoLISP, however it does point towards the direction Autodesk is
taking us. Although we have not compiled any exact bench marks
yet, programs running under Rx ADS show an improvement in
throughput. The amount of improvement you would experience
depends on the number of times a program makes calls to the
AutoCAD system. One good incentive For porting to Rx ADS is that
future releases of the AutoCAD APIs for other products will exist
in Rx ADS before they exist in ADS. It is rumored that some
libraries in the future will only be available to Rx ADS
applications.
It was not easy to convert AutoLISP to ADS, and it won't be any
easier to convert AutoLISP to Rx ADS. (Although in both cases,
the gains in terms of speed may make the effort worthwhile.)
However, updating existing ADS routines to work under Rx ADS is a
very straightforward process. To give you an idea of the
complexity, the only problem we had was in figuring out how to
run the Windows Visual C++ programming environment properly.
Which, by the way, is the programming tool you use to create Rx
ADS programs. Our experience with programming environments has
been plentiful, and the Visual C++ package from Microsoft is very
nice. But it is also quite different from what we had worked with
in the past, so it took some getting used to. The biggest
advantage for serious ADS programmers is that the Windows NT
Visual C++ program creates executable programs for NT, Windows,
and DOS. That's because Rx ADS programs are DLL that are bound to
the AutoCAD program. So far, our experiments have been strictly
under Windows NT, but by the time of this printing, that
situation will have changed.
Because Rx ADS programs are DLLs, they do not have the familiar
MAIN entry point in a C pro- gram. Instead the function
acrxEntryPoint() serves as the main program name. This entry
point is used by AutoCAD when the load request is first issued,
when a drawing is saved or loaded, and for other reasons much
like the return values of the ads_link() function.
Rx ADS programs don't go away or just wander off between drawings
either. Once an Rx ADS program is loaded, it continues to live
between drawings. Event messages are passed to the Rx ADS
application when the drawing changes; however, the complete
program remains intact, and the only requirement is that function
names defined using the ads_defun subroutine must be defined
again when a drawing is loaded. Another nice feature of Rx ADS
programs is that they can be loaded as AutoCAD is loading and
actually begin to execute before AutoCAD is completely up and
running.
All in all, Rx ADS is the right direction for Autodesk to be
going. Using tighter communications between programs means that
eventually more interactive gates will be opening up between
AutoCAD and our programs. Of course, there is still a lot of room
for improvement, however, Autodesk has done a very good job in
not only communicating its intent with the developers but also in
providing good tools to get the job done right.

Solid Modeling and 3D
by John Wilson
One big, and certainly pleasant, surprise is that AutoCAD Release
13 replaces the Advanced Modeling Extension (AME). This change
does not mean that AME has disappeared altogether, there is a
provision in Release 13 to convert AME solid models into the new
format.
How do Release 13 s solid modeling capabilities compare with
those of AME? They are about equal in their ability to create
solids with primitives, extrusion, and revolution. All of the
Boolean operations are in Release 13, but you cannot take
composite solids apart as you can in AME. Release 13 can slice a
solid into two pieces and is more flexible than AME in defining
the cutting plane-but it isn't the same as separating a composite
solid. No special commands make fillets and chamfers on solids
because AutoCAD uses the standard fillet and chamfer commands.
Both of these operations work better than their counterparts in
AME. They are intuitive and convenient to use, much faster, and
can handle shapes that AME will not accept. Also missing, because
they are no longer needed, are commands to transform a solid into
a polyface form and back to a wireframe form. Now, when you
invoke the hide or shade command, AutoCAD automatically converts
solids to a polyface form.
Release 13 has a command for making a cross section through a
solid, just as AME has. The resulting entity is a region, so data
on area properties is readily available. Some of you, however,
are likely to be disappointed to find there are no other commands
for making 2D images from a 3D solid.
3D Wireframe Construction and Editing
Some new features for 3D wireframe construction and editing in
Release 13 are unspectacular but important. Most of these new
features have been borrowed from AutoSurf, Autodesk's
sophisticated 3D surface modeling program released about one year
ago.
In previous versions of AutoCAD, entities had to be in a plane
parallel to the User Coordinate System (UCS) before you could
fillet, chamfer, trim, or extend them. Now you can perform these
operations no matter how the entities are oriented within the
UCS. Trim and extend can even be view-dependent entities to be
trimmed or extended, but they do not have to be in the same plane
as the boundary. Break also works better. Breaking entities that
were not parallel to the UCS has been an uncertain operation in
which AutoCAD reflected the selected break point off of the UCS
so the entity was actually broken at another location. Now, an
entity is broken at the pick point.
Picking overlapping entities, which commonly occur in surface
models, is easier. You can now hold down <Ctrl> as you make a
pick, and AutoCAD will select the bottom-most entity and
highlight it. If this entity isn't the one you want, continue to
pick on the stack as you hold down <Ctrl>. AutoCAD will work its
way up until you accept an entity or until it reaches the top, in
which case, it will cycle back to the bottom. This feature is
especially useful For those commands (such as rulesurf) that
won't accept a window or a crossing selection.
Release 13 has a command, named group that allows you group
existing entities together with a name. Then, you can use this
group name to build a selection set. Members of a group do not
need to have anything in common, except that you want them to be
grouped together. Groups will be useful when you are working with
a crowded 3D model.
A new wireframe entity, which goes by the name of spline, is
similar to a 3D polyline in that it has zero width and it can
twist and turn through 3D space. Unlike a 3D polyline, it is
always smoothly curved. Splines can be trimmed, stretched, and
broken, but there is no provision for moving their control
points. The new spline ellipse will also be useful for wireframes
because you can draw just the section of the ellipse you need.
You'll no longer have to draw a complete ellipse and then trim it
to obtain the portion you want.

cadua.55milanv,
Pre dva-tri meseca vodila se diskusija u temi CAD o
mogućnostima prenošenja urbanističkih karata na PC. Pošto mi je
ovo jako potrebno, molim za nekoliko konkretnih informacija (na
osnovu pomenute diskusije).
Karte (1:500) će biti skenirane skenerom A0. Potrebno je da
se izvrši vektorizacija, i spajanje.
- Da li je moguća automatska vektorizacija?
- Kako pretpostavljam da prethodno nije moguće uraditi na
dovoljno kvalitetan način, mislim da je potrebno skenirane karte
staviti kao podlogu u ACAD i preko njih crtati. Koji programi
ovo omogućavaju? (Mogu li da rade u ACADu 12 for Windows?)
- Kako izvršiti povezivanje (i eventualno, malo, rotiranje)
ovih karata u jednu veliku?
Toliko za sada. Verovatno je da ću na osnovu (eventualnih)
odgovora imati potpitanja:), ali otom-potom.
Hvala, unapred.

ovo nije loša varijanta, ali se postavlja pitanje koliko je neophodna?
Možeš da ostvariš to uz pomoć kvalitetne video kartice sa grafičkim
procesorom (Rasterex) i sa dosta memorije na njoj i softverom mislim da
se zove ARCcad ili tako nekako (Gremline?) a tu je CADoverlay ESP koji
radi sličnu stvar.
Posledica rada sa rasterom je da ploter mora da štampa i raster,
znači tu dolazi u obzir termalni, ink-jet, laserski isl. ploteri.
Sve je ovo vrlo skupo a softver je lock-okovan. Oko detalja je
najbolje da zovneš OSU.

Uz pomoć gore navedenog softvera.

Izgleda da me nisi razumeo. Cilj mi je da "ručno"
vektorizujem karte, tako što bi _privremeno_ stavio rastersku
sliku kao podlogu preko koje bih na klasičan način precrtao sve
važne (a svi su važni) objekte. Situaciju bih iskoristio da
razne tipove objekata prikažem raznim Layer-ima. Po završetku
ovog postupka, raster bih uklonio kao da ga nikada nije bilo.
Posao je, očigledno, veliki, ali ne vidim bolji način. Zna
li ga neko?
║║ Sve je ovo vrlo skupo a softver je lock-okovan.
U kom smislu je skupo? Da li je skupo vreme i uloženi trud
(sa ovim se slažem, zato i pitam postoji li bolji način), ili je
skupa oprema (radim sa 486/66/32MB/hard keš/A0 skener...)?

Razumeo sam te, ali postavlja se pitanje preciznosti tako urađenih
podloga. Javlja se tu višestruka greška i to:
1. kod ucrtavanja podataka na podlogu (mislim na ručno ucrtavanje u
geodetskoj ustanovi) usled čega se javlja mala greška kao posledica
ljudske nesavršenosti i stare tehnologije ucrtavanja tih mapa
2. greška usled deformacije papira na kome se podloga nalazi, tokom
vremena (temperatura, vlažnost i sl.)
3. greška usled deformacija papira prilikom skeniranja
4. greška usled zamene rasterske linije koja ima svoju fizičku
debljinu sa vektorom čija je debljina 0.
E, sad ako ovako vektorizovana podloga, služi za neke precizne razmeravanja
i crtanja onda bi ove greške bile dosta uticajne, a ako je to potrebno za
izradu nekog GIS-a onda stvar funkcioniše.
Situaciju bih iskoristio da

Ima softver za vektorizaciju rastera i zove se RX-Vectory i proizvod
je firme RASTEREX.

Rad i vreme su u ovoj zemlji uvek bili najjeftiniji. Skupa je oprema
(A0 skener, vrlo kvalitetna video karta, grafička tabla, aždaja od ra-
čunara), što vidim imaš, i naravno softver koji nije javno dostupan već
se mora skupo platiti.

Osnovno pitanje je da li iza ovog posla stoje neke pare. Samo
savetom ne moze se pomoci, mora nesto da se i plati. Mi smo
ovakav posao radili, uz pomoc specijalnog softvera, i rezultati
su dobri - za arhitektonsko-urbanisticke potrebe. Preko skenirane
podloge (u formatu neke bit-mape) se AutoCadom digitalizuju vektori,
dakle rucno (sa programima za vektorizaciju nemamo dobro iskustvo,
verovatno nismo naboli pravo setovanje - a ima more parametara),
a decimetarska mreza sluzi za korekturu razmere i ugla.
Druga (bolja a mozda i jeftinija) varijanta je naci geodetu koji
je voljan (a i u stanju) da isporuci listu koordinata koje se
jednostavno ukucaju u AutoCad. To je skoro apsolutna tacnost a
dobija se i vertikalna predstava (z-koord.)
Dakle, ako se ne snadjes sam, i ako si spreman na komercijalni
aranzman, pisi na mail da ti damo kontakt sa ljudima koji to
mogu da odrade.
PS.
Sad mi pade na pamet "susterska" varijanta:
Skeniranu podlogu (200 dot/inchu je dovoljno dobro) uvuces u
Corell Draw! pa u drugim layerima "crtas" - decimetarske krstove
u posebnom layeru. DXF out, pa u AutoCAD pa SCALE - u svetske
mere koristeci otstojanja krstova kao reper. Mi nemamo bas
mnogo iskustva sa Corellom - ali mozda ... B)

Trpe oba, ali ti je za swap file neophodan nestakerisan disk.
Minimalna konfiguracija? Pitanje je šta ćeš da radiš. Ako ćeš da "vrtiš
slova", jedan 486 sa 8 MB ti je apsolutni minimum. A ako ćeš da radiš
veike arhitektonske prezentacije, ni Pentium90 sa 64 MB ti neće biti
dovoljan. Poslednjoj animaciji koju sam radio na ovakvoj konfiguraciji
trebalo je oko 4 dana za rendering 270 frame-ova.

Na svom disku imam jednu Stakerovanu particiju, a 3DS držim na drugoj.
U radu nema nikakvih problema.Mislim da nije poželjno staviti 3DS
na Stakerovanu particiju zbog swap-a.Došlo bi verovatno do velikog
drljanja po disku i usporenja rada.
Ako već hoćeš to da uradiš mislim da neće biti problema oko samog
funkcionisanja programa.
Bilo je dosta reči oko minimalnih konfiguracija za rad u 3DS-u
u temi cad.Moja preporuka za normalan rad je 486DX2/66, 8(16)Mb RAM,
HD 540Mb, neka bolja video kartica i color monitor.
BTW. Kada smo već kod swap-a, poželjno je imati na disku bar dve
particije.Dešava se da swap popuni sav prostor na particiji
koja mu je dodeljena i time onemogući snimanje projekta.

01.03.'95, tačno u podne, u palati Beograđanka",u restoranu STB-a
održana je prezentacija programa AutoCAD 13 (verzija za DOS). U prepunoj
sali, bilo je i stajanja, goste je najpre ispred organizatora, Instituta
za permanentno obrazovanje "Vinča", pozdravio Dejan Šunderić.
Uvodno izlaganje o novom Autodesk-ovom paketu imao je Petar
Damjanović iz "OSE", koja je dala softver na testiranje. Bilo je reči
o trenutnom stanju u Autodesk-u i planovima daljeg razvoja.
Testiranje i prikaz obavili su predavači "Vinče" i članovi
asocijacije CADUA: Slobodan Lazić, Nebojša Bulović i Nebojša Novković.
U opuštenoj atmosferi krenula je lagana šetnja po meniju i upoznavanje
gostiju sa novostima u N°13. Počelo je preko helpa, a priča je završena
sa novostima iz 3D modeliranja i vizuelizacije. Najviše novosti prikazano
je u DRAW meniju, a prijatne novine su, rad sa tekstom, integrisanje solid
modelara u sam program, asocijativno šrafiranje,...ukupno oko 200 noviteta.
Prezentacija je nastavljena sa pitanjima posetilaca i odgovora očito
dobro pripremljenih predavača. Formalni deo skupa je završen konstatacijom
da se i Autodesk lagano, ali sigurno usmerava prema Windows platformi, na
žalost mnogobrojnih ljubitelja DOS-a.
Druženje je završeno u prostorijama "Vinče" uz prigodan koktel.

New Entities in Release 13
***Associative leaders
LEADER
From point:
To point:
To point (Format/Annotation/Undo)< Annotation>:
AutoCAD leaders are now true entities, created by the LEADER
command. The leader text, however, is not a part of the actual
leader entity, but is an MTEXT entity which needs to be moved
separately (hint: use the stretch command or grips when moving
leader text). Use the format option to select straight line
segments or splined and whether to draw arrows or not. Use the
annotation option to select what type of item to place at the end
of the leader, either the default mtext, a block insert, or a
tolerance entity. Use dimension styles to control the appearance
of leaders by setting the parameters for the leader dimstyle
family Note: Leaders created the old way -- from the DIM: prompt

***Construction lines
XLINE
Hor/Ver/Ang/Bisect/Offset/<From point>:
Construction lines extend for an infinite distance in either one
(for rays) or two (for xlines) directions without affecting the
drawing extents, but otherwise act as normal entities. They will
even plot unless the layer they are placed on is turned off or
frozen.
See also: Command Reference: RAY, XLINE
Users Guide: Chapter 3: Drawing with Precision
***Ellipses
This is a true mathematical ellipse, no longer one approximated
by a splined polyline. This means that ellipses now have center
points and quadrants, all of which can be snapped to (and which
also display grips). The isocircle option is used to create
"circles" when drawing in an isometric plane. While it is not
possible to convert older spline-type ellipses to Release 13
ellipses, it is possible to create them, by changing the system
variable PELLIPSE from 0 to 1.
See also: Command Reference: ELLIPSE
Sysvars: PELLIPSE
***Geometric Tolerancing
The TOLERANCE command creates geometric tolerances, which define
allowable variations from the exact geometry defined in a
mechanical drawing. Tolerances can also be created using the
Annotation option of the LEADER command.
See also: Command Reference: TOLERANCE, LEADER
Sysvars: DIMLCLRE, DIMCLRT, DIMGAP, DIMTXT, DIMTXTSTY,
DIMSTYLE, DIMASO
***Multiple parallel lines
The mline entity allows for the definition of parallel line styles
with up to 16 elements. Since linetype styles can now include
shapes in their definitions, mline styles can be created (with the
mlstyle command) to represent such things as walls complete with
insulation, or railroad tracks. Mlines can have a background fill
color, but can not have rounded joints or curved segments. MLEDIT
is used to change how intersecting mlines appear, allowing the
user to perform simple Boolean operations when joining and
splitting mlines.
See also: Command Reference: MLINE, MLEDIT, MLSTYLE
Sysvars: CMLJUST, CMLSTYLE
***OLE objects
AutoCAD can now accept embedded or linked objects from other OLE
applications, such as Microsoft Word or Lotus 1-2-3 for Windows.
To insert an OLE object, select any portion of the document in the
other, copy it to the clipboard and then use the PASTESPEC
command, or select Paste Special from the Edit menu. Use the
command OLELINKS to list or change any of the OLE objects in the
drawing. OLE objects do not plot and are not visible on platforms
other than Windows and Windows NT.
See also: Command Reference: COPYLINK, OLELINKS, PASTESPEC
***Overlaid Xrefs
Overlays are an enhancement to Xrefs, allowing you to reference
one drawing, and that drawing only, even if it contains Xref or
overlay attachments of its own. For example, if a drawing of a
floor layout Xrefs several drawings containing electrical wiring,
gas lines, and other utilities, attaching the floor drawing to a
drawing of the reflected ceiling plan will show all of those
drawings, while attaching the floor drawing as an overlay will
show only the floor layout in the reflected ceiling plan. Insert
an overlay using the Overlay option of the XREF command.
See also: Command Reference: XREF
Sysvars: XREFCTL, VISRETAIN
***Paragraph text
MTEXT
Attach/Rotation/Style/Height/Direction/Insertion point>:
The MTEXT command is used to create the new multi-line text
entity. Its major advantages are word-wrapping, the ability to
change fonts and font attributes - such as color, height, or
obliqueing - within one line or paragraph (with the style
option), and the ability to define the bounding box for the text,
as well as where the insertion point is relative to that box
(with the attach option). The new spell checking function works
only with mtext entities, not the older text entity.
See also: Command Reference: MTEXT, MTPROP, SPELL
Sysvars: MTEXTED, FONTALT, FONTMAP, TEXTFILL, TEXTQLTY,
TEXTSIZE, TEXTSTYLE
***Splines
True mathematically-defined splines are a replacement for
spline-fit polylines with lots of short line and arc segments.
The SPLINE command is used to create splines, and its Object
option converts existing splined polylines to true spline
entities.
See also: Command Reference: SPLINE, SPLINEDIT
Sysvars SPLFRAME
***3D Solids
Release 13's native solid entities and editing commands replace
the AME program, and most of its functionality. The commands used
to create 3D solids are: BOX, CONE, CYLINDER, SPHERE, TORUS,
EXTRUDE, REVOLVE and WEDGE. Editing commands specific to solids
are: UNION, SUBTRACT, INTERSECT, SECTION, SLICE. Also, many of
the standard editing commands now work on solids, including
FILLET, CHAMFER, TRIM, and EXTEND. Use the AMECONVERT command to
translate AME models when opening a Release 11 or 12 drawing.
Regions are also now defined as native ACIS entities. For
information on creating and editing solids, see Chapter 11 in the
AutoCAD User's Guide.

▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄
BEOGRAD, 11. aprila (Tanjug) - Drugi jugoslovenski seminar o primeni
CAD tehnologije "CAD Forum '95" održaće se 13. i 14. aprila u Novom
Sadu, najavili su na današnjoj konferenciji za štampu organizatori
tog programa.
Prema rečima generalnog direktora preduzeća "Pro-inga" Gorana
Vukobratovića, organizatora seminara, CAD tehnologija podrazumeva
sistem arhitektonskog projektovanja uz pomoć računara.
"Cilj CAD je da se pomogne inžinjerima i arhitektama pri projektovanju,
da se proces projektovanja, koji inače dugo traje, skrati, rekao je on.
Na predstojećem seminaru radovima iz oblasti CAD predstaviće se više
od 400 inžinjera, arhitekata, geologa, programera, rekao je Vukobratović.
Potpredsednik Srpske akademije nauka i umetnosti Nikola Hajdin rekao
je da je reč o velikom skoku u projektovanju, jer "CAD je produžena
ruka uma, koja već talentnovanom čoveku omogućava da brže i lakše
kreira".

Novost sa CADForuma No2 u Novom Sadu
U okviru Workspohova koji su trajali oba dana bilo je vise manifesta-
cija vrednih paznje, onih placenih i onih dobrovoljnih od strane gos-
tiju i izlagaca. Jedna, dobro odmerena i na pravi nacin plasirana po-
godila je interesovanje velikog broja prisutnih. Clan CADUA, poznat-
iji kao g.pp Gremlin, u 'slobodno vreme' glavni i odgovorni Racunara,
je odlucio da pomiri svoje dve velike 'kompjuterske' ljubavi AutoCAD
i 3DS i isprica cetrdesetominutnu pricu o tome kako lepo umotati svo-
je CAD delo ne bi li ono postalo proizvod koji je moguce prodati za
sumu dostojnu podnosljivog zivljenja i rada.
Ovo predavanje, nazvano "Od inzenjera do ilustratora" od strane cove-
ka koji je vise godina radio posao "pakera inzenjerskih resenja u at-
raktivnu graficku formu", koji je poceo u vreme kada se time kod nas
jako mali broj ljudi bavio, a radio je dugi niz godina u jednoj, bar
u to vreme, od najbolje opremljenih beogradskih kompjuterskih firmi za
takvu vrstu usluge, nije moglo da nebude interesantno za prisutne.
Spremnost predavaca da sa prisutnima podeli neke od tajni 'zanata'
stecenih dugogodisnjim radom je ovaj dogadjaj dovela na mnogo visi
nivo, a njegovo iskustvo govornika u 'prodaji' (tkzv. osina skola) je
ucinilo da vreme koje je oduzeo slusaocima prosto proleti.
Problem neumetnicki orijentisanih inzenjerskih struka koje trebaju
da daju prikaz svojih proizvoda, znaci svi osim arhitekata, je, bar u
vecini pojedinacnih slucajeva, nedostatak makar formalnog obrazovanja
o bojama i teksturi, svetlu i njegovom uticaju na psihu gledaoca i
potencijalnog kupca.
Drugi problem, ovaj uglavnom pripadnika svih 'inzinjerski' orijentis-
anih struka je nedovoljno poznavanje kompjuterskih alata prisutnih na
'trzistu'. Nepoznavanje tehnika rada u kombinaciji sa hronicnim nedo-
staktom materijalnih sredstava da se nabave 'jake' masine sposobne da
delom sakriju neka neznanja korisnika dovodi do nezadovoljavajucih
rezultata na upotrebi racunara u vec pomenutim svrhama.
Predavanje je prisutne upozorilo na gore navedene probleme i uputilo
na bar neke od pravih pravca za resavanje pojedinih konkretnih probl-
ema. Prica o optimizaciji resursa i tehnike rada, o planiranju izlaz-
ne forme i nekim nacinima da se to uradi pre nego sto se pocne sa ra-
dom pomocice prisutnima da ustede sate rada nad nekim detaljima koji
ce se u krajnjem produktu zbog tehnickih karakteristika izlaznog ure-
djaja izgubiti.
Saveti kako izvesti samo ono sto ce se u krajnoj varijanti videti, a
i to na nacin koji omogucuje dobar odnos rada i rezultata, gde i zas-
to ne solid kada moze nesto manje zahtevno, sta prenaglasiti svetlom
a sta bojom, kako usaglasiti boje koje vidimo na racunarskom ekranu
sa onima koje ce se pojaviti u papirnoj formi ili na TV ekranu i mno-
go, mnogo drugih 'sitnih' detalja su bili poklonjeni slusaocima.
Predavanje je bilo samo priprema za rad koji ce po recima autora pos-
lati za sledeci CADForum. Kako je vreme za izlaganje na ovakvim mani-
festacijama ograniceno i nebi bila ispunjena osnovna namera autora da
vise zaintersuje i detaljnije upozna sa ovom materijom siri krug lju-
di, u vremenu izmedju dva CADForuma ce svoje ideje plasirati i na dr-
uge nacine. Jedan od poteza koji ce u tome pravcu biti povuceni je i
stampanje ovog izlaganja, naravno u sazetijoj formi od one koju je
imalo na skupu, u sledecem broju CADUA biltena "Presek".
