GUI
Graphical User Interface (see MFC or DCL)
alias
command abbrevation, via the pgp or c:
alisp
AutoLISP, cool script language for AutoCAD (not a SCRIPT!), .lsp extension, see also lisp (has anbody a lisp which ...)
lisp
an AutoLISP file/program, "has anbody a lisp which ..." also:
Lisp
a computer language (not AutoLISP), see CL
CL
Common Lisp (a huge standardized Lisp), has nothing to do with alisp
xlisp
a free small OO Lisp (but more like Scheme) by David Betz, the basis for AutoLISP see news:comp.lang.lisp.x or comp.cad.autocad (sometimes)
AME
Advanced Modeling System, the old (R12) CSG modeller, was too slow
acomp
a free r12 lisp compiler, supported for the international releases, see bi4
C:
a lisp function prefix that enables that function to be called as ordinary AutoCAD command
cis
Compuserve, mostly their forums. the adesk forum is similar to cca but moderated (means censored) by adesk (really!)
cca
comp.cad.autocad newsgroup (Note: aca for alt.cad.autocad is not used)
brep
Boundary Representation, solids made of faces, not primitives. Fast but primitive
CSG
Constructive Solid Geometry, solids made by primitives and boolean combinations, slow, but advanced technology, stores its creation history, best in conjunction with intermediate brep's
quad
a face of 4 points in 3d space (just for no-see-trough), used by acad, also used in the term quad-mesh (mesh of quads, acad meshes), a quad is very hard to keep planar, see triangle
triangle
a face of 3 points in 3d space (for no-see-troughs and coloured faces), used by most of the simple renderers, i.e 3ds, always planar, see quad
polygon
closed connected lines, usually planar, just list of pts, such as (p1 p2 p3 ... pn)
pt
a point, list of two or three numbers, (0 0 0)
pts
points, a list of points, ((0 0)(1 0)(2 2)), may be a polygon
pline
acad polyline, a complex entity consisting of a header with general attributes and vertices with point and bulge (curve) information
bulge
number in a vertex. group 40 in a vertex. see the AutoLISP FAQ for definition, maths and functions
group
* entity attribute field, integer number between -4 and 1099. car of an association list. see the AutoLISP FAQ
* sometimes also used for cca: "the group"
* with R13 there are also "Groups", similar to blocks, but you may edit subparts of a Group too
block
a definition of an INSERT entity, collection of acad entities (also other inserts). Often you mean insert (the entity) when you say block (the definition). Often the most interesting and confusing part working with acad. see also layer
layer
a common attribute as string with max 32 chars. every single entity has a layer. default: "0", often described as foil you work on and put together but I dont like this definition. It's simply the only common attribute used to group entities together (same as with blocks or groups) and to manage visual information of entity groups (color, linetype, visible or not, editable or not) Former competitive cad programs had only a restricted number and features of layer-alikes that's why they didn't make it.
pen
plot pen, often the plot color, pen definitions are stored in .pcp files. Note: white is black on white paper and black on a white screen background
3ds
3D Studio, a top product by adesk, written by the Yost group, bought by adesk. standard program for Visualization and Animation
max
3DStudio Max, the latest 3ds, nt only, completely rewritten, using heidi
lib
a software library, a collection of compiled functions, normally documented, otherwise useless
compiled
not readable program (lot of weird characters), but runs quite fast, sometimes also encrypted (fas, bi4) to see only weird characters, cannot be uncompiled, besides not really compiled programs like VB/winhelp. These are only compressed,encrypted,indexed and commonly misspelled as compiled. For those who think of compilations the previous sentence is not true.
VB
Visual Basic by MS, a fine GUI development and programming tool, will be supported by R14, very slow and huge
Delphi
Borland Delphi Pascal, the VB counterpart for the more advanced. fast and huge (Tony says it's faster than Watcom)
MSVC
Microsoft Visual C (but meaning C++), the most complex VB counterpart :) The compiler R13 is compiled with and you have to use to do ARX. very fast and huge. see Watcom, VB, Delphi, fastest compiler and MS
Watcom
Another compiler, by the University of Waterloo, now a company. The fastest commercial C/C++ compiler, for command line fetishists. gcc++ is faster, CMU CL the fastest, really! both of them are free, R12/Win was built with it. very fast and not small. see fastest compiler
fastest compiler
compiler which produces the fastest code, usually the slowest compiler, often also used as "who has the biggest", see Watcom
GIS
Geographic Information System, has a lot to do with extensive point clouds, 3d meshes and long polylines, also streets, slicing and dicing
fas
a compiled Vital Lisp program, see bi4 and ViLL
bi4
a acomp compiled lisp program, see fas and acomp
DXF
ascii or binary exchange format instead of dwg's, other program may read it
DWG
an acad drawing file, r13 dwg's have a different structure than r12 dwg's
LT
AutoCAD Lite, the cheap AutoCAD without AutoLISP, win only
NAAUG
North American AutoCAD Users Group
(and all the other groups have similar abbrevations)
SAUG
see NAAUG
acadapp
the ADS program which has all the dcl and proteus code and some more. there are often problems with this file. see the acad faq
BASE.DCL
base definition file for dcl's. The typical newbie error. see the acad faq
exp
extension for R12/DOS ADS programs or the ADS program itself.
pgp
the pgp: acad.pgp, support\acad.pgp, collection of command aliases, "change it in the pgp",
only seldom PGP: pretty good privacy, a free encryption program, "send it to me via pgp"
R12, R13, c4, c4a, prec4, preR13...
The various acad releases, R14.01 ist the latest, R13/Win is obvious
C++
huge c successor, OO computer language, the language R13-R14 is programmed in (spelled "See Plus Plus"), unfortunately most of beginners try to learn this awful language (better try lisp, perl or java)
C
old and widely used computer language, some kind of awful macro assembler, the language all preR13's were programmed in
OO
Object orientated. A better way to program userdriven programs in comparison to program driven users.
X
X Windows, not a GUI, more a protocol, but often used as a term for the unix GUI or "unix windows"
script
file with keystrokes as entered from the keyboard in acad to run more commands, has .scr extension. Note: you also often say "script" for a interpreted small program, such as a perl script, or some kind of a macro script.
MNX
compiled menufiles (not decryptable)
SLB
slide library, collection of slides
SLD
slide file, created by _MSLIDE, used by _VSLIDE and others
plt
a plot file, usually a HPGL/2 on plotters and a PCL in laser printers
HPGL/2
extension to HPGL, which allows pixel images also and some filled stuff
HPGL
Hewlett Packard Graphics Language (really?), understood by almost every big plotter and some expensive printers. awful stuff because it always comes out the wrong way round and wasting therefore a lot of paper, simply ignoring if you say 0 or 90 degrees (this is called optimized)
PCL
now what does this stand for? Used by HP laserprinters and others to define a printed page layout. lot of "&"
PS
PostScript. File format and page describing and language by Adobe. Only expensive plotters understand it but then you don't have to hatch anymore. See RIP or SoftRIP
RIP
Raster Image Processor. Usually a RISC chip inside a Postscript plotter which converts postscript commands to pixel. See SoftRIP
SoftRIP
Software RIP. Usually Ghostscript, which is free. adesk also purchased a license to support PS plotters better.
perl
yet another computer language, in between c, awk and c-shell, free and fast. very often used by unix programmers, but has nothing to do with acad
Whip!
slow acad graphic driver, but the first by adesk, which uses a fast display list
Whip! plugin
Whip! add-on to create DWF's (no sado-maso stuff)
DWF
some kind of 2D vrml but faster, enables real time panning and zooming in html documents and with new ocx plugin in every OLE capable win document too. Not seen so far but will be definitely a standard soon. has hyperlinks
vrml
say "Vörmel". 3d geometry format, used by realtime flytrough programs, mostly plugins. now v2.0, has hyperlinks
HOOPS
quite impressive 3d graphics library, created by Ithaca (a bunch of computer graphics professors and specialists, who know ancient greece) and bought by AutoDESK, used i.e in mechtop, 3ds max, softdesk block preview dcl's (the real time stuff), now renamed to Heidi
Heidi
see HOOPS, get the libs at adesk's ftp site to support it
GL
3d graphics library, common name for the Microsoft Implementation on NT of Open GL, which is a free Irix GL (Graphics Library by Silicon Graphics). knows just polygons, no solids. see Hoops
CDK
adesk's VR programming library, unfortunately not very successful but technogical a top product, see VR and vrml
Softengine
the best graphic drivers for acad. by Vibrant Graphics Inc.
ViLL
Vital Lisp, the best alisp tool, a product by Basis Inc.
lpp, l++
the language ViLL is written in (spelled "Lisp Plus Plus")
VR
Virtual Reality. you know, headsets, slow interactive 3d graphics and so on.
3d plotter
not a plotter but a laser device which creates 3d models.
Vector
Solidfill for pre-r14. product by Jerry Workman which does solid filling and some more polyline stuff
microstation
Another CAD program, 10%, by Bentley. A lot of the cca readers will tell you that they will switch over to micorstation but will never do it. It has no AutoLISP and is about the same huge and complicated as acad (but easier to learn for acad users, and as hard to learn for beginners because those have nobody to ask but the bentley guys :), often abbrevated as ustation
ustation
= microstation (u looks like the greek letter for micron)
ustn
= ustation
real cad
some refer in comparison to the simple acad or ustation to solid modelers such as catia, ideas, even mechtop, ... and some others mean acad in opposition to simple cad programs. it depends
mechtop
Mechanical Desktop. high end adesk product based on acad and some addon progs (autosolid, designer)
Solidfill
solids used as hatch replacement
Solid
* either a filled 2d entity consisting of 3-4 points (used for historical reasons), or
* a 3d solid as in every other CAD program (i.e. a polyhedron completely surrounded by faces)
polyhedron
a solid which is completely surrounded by planar polygons
convex
...
concave
...

Internet specific:

(see also http://iasw.com/glossary.html or the hackers dictionary)
Internet
the Internet
internet
this may also be a connection of some internal networks, such as some intranets, but we normally mean Internet when we write internet
net
Internet, "it's on the net", means its reachable via TCP/IP, mostly referred to newsgroups or webpages, can also be ftp
unix
kind of old but stable family of computer operating systems.
TCP/IP
the internet software protocol and naming convention. should work in/after a nuclear war, because of chaotic in-time routing. Consists of TCP and IP
DNS
Domain Name Service. A program which does the domain name -> IP translation
NIC
Network Information Center. At a InterNIC you register domain names.
CERN
European high energy physics research laboratory, in Geneva,
Switzerland. there the internet was invented
URL
Union Resource Locator, a internet naming convention,
i.e. http://www.autodesk.com:80/techdocs/techdoc.html -> protocol, server, port, directory, file
IP
Internet Protocol, a collection of 4 numbers between 0 and 255, dot seperated (such as 129.27.2.1), 129 is austria (.at), 27 is .tu-graz
domain name
one of the names of a certain IP number (to better remember it), converted by a DNS (service) server or a DNS (server)
TCP
Transfer Protocol (this is the weirdest part of internet, allows totally chaotic routes the parts of the transmitted file are going. Check out the command TRACERT on Windows)
web
usually www plus newsgroups.
www
graphical frontend to the http protocol, makes proficient use of the "natural extroversion of the typical internet user"
w3
www or the international www consortium that restricts too much HTML tags :) namely INRIA in france and MIT in US, before it was CERN
http
Hypertext Transfer Protocol, usually on port 80
HTML
Hypertext Markup Language, semantics of tags and attributes. a SGML specification. similar to TeX but not really that elegant. Managed
by the w3 org and enhanced in the unbelievable struggle between netscape and ms, mostly not to its best, current version 3.2.
msie
Microsoft Internet Explorer (also MS IE or just IE)
ftp
File Transfer Protocol
irc
Internet Relay Chat (talk in real time by typing very fast about nonsense)
vi
quite popular unix editor (there are often religious wars with emacs users in comp.editors)
java
c++ improvement, quite lisp alike OO language, but easy to learn for C++ programmers. big hype now and will be quite useful in a few years
java script
not java! a http scripting language, embedded in html docs. see CGI
robot
a web program which visits sites automatically to gather search engine information mostly, not a human alike machine!
spider
same as robot, no animal!
virus
a self-replicating program which infects computers. most of them are harmless but they create a lot of trouble if detected or do some harm. Often the scapegoat of mysterious MS Windows inconsistencies and the lack of cheap system design.
hacker
not a cracker! intelligent, skillfull, idealistic programmer
cracker
not a hacker! removes password checks or copy protection of programs, breaks into other machines.
news
not the news but the articles in the newsgroups. they come from your news server, in opposition to ftp or http files which stay (or at least should) in the home machine
bandwidth
How much information (text, images, video, sound) you can send through a connection. Usually measured in bits-per-second. When used in conjunction with "wasted" the length of an article or sig.
sig
Signature, the (hopefully not more than 3) lines at the end of an article or mail. for the dummies who cannot read headers, for free advertising or for some cute zen canons, see spam, Tony or Rod Young
spam
unliked information. not only "Make money", "Get rich", "Call me" also wasting too much bandwith with useless information. (a quite modern word, such as punk in the 70's or hip in the 80's)
thread
a group of messages on a newsgroup that relate to each other. Mostly the same subject title with only the "Re:" prefixed on the followups, but also a set of Referred messages, created by a followup.
followup
a news posting with reference to another, the default subject title is prefixed with Re: then, but you may also change the subject. Some newsreaders arrange those "threaded" (=indented), some create a new thread, see thread
Followup-to:
you restrict any followup per default to this newsgroup. usually done if any wished comment or answer should not be posted to the other groups to which the post may be posted as well. see crossposting
bincancel
an automatic script in the big 8 newsgroups (comp, rec, ...) which decides when a specific post has too much binary data attached. There's a bincancel FAQ and its use should not be questionized again. For posting binaries there are a lot of appropriate binary groups, (i.e comp.binaries or alt.binaries.misc) groups with bincancel running are discussion groups. you may create your own alt.binaries.cad or alt.cad.binaries newsgroup if you want to. It depends on every news admin if he will carry that group.
Expire
the number of days how long a single news server carries an article (message, post). comp.* groups with a lot of traffic usually have expire 8. comp.cad.autocad had usually 14, but some newsadmins switched it to 8. alt.pictures.binaries.* may have a expire 2, news.answers 30, but the usual number is 14 for discussion groups.
crossposting
if there are more than one newsgroups in the newsgroup header. the way to post to more than one group by combining their names with a comma "," at the newsgroup line. In opposition to post it independently to every single group instead which should NOT be done! crossposted articles are stored only once at the news server. you also crosspost if you followup to a crosspost and don't set a followup-to
snail mail
mail trough slow conventional, (in some countries) expensive and unreliable channels.
home page
The html page that appears when you press "Home". Default: http://home.netscape.com (I dont have msie) Term clarified by Robert Cailliau in CERN, not in the particle collider, in the conference room. With "xx's home page" you usually mean xx's welcome page. Well, often it is the same.
welcome page
the first page that appears on top of a subcollection with omitting the filename, often called "home page" or index, you know it as index.html or INDEX.HTM in your public_html directory or as page which appears when you omit any directory and filename in a URL.
frames
a feature in HTML pages every surfer (=reader) hates and a lot of writers like. Simply don't use it if you don't want to annoy surfers. you cannot make bookmarks on subframes, you dont know on which page you are, you cannot press "back" and "forward". fancy headers or footers may also be created by SSI
surfers
web surfers. web readers. Internet readers which click their way trough the world. maybe because they get lost in the waves as wave riders. They won't get wet. Only a few wave riders or windsurfers are Internet surfers. They have better things to do. (I used to be a windsurfer and became unfortunately a web surfer now)
tables
the only way to arrange text side by side in HTML docs. the text can be displayed when the whole table is read, so use not long tables. see graphics
graphics
images in HTML docs which are usually turned off by surfers who have to pay for their online time or want faster access. Unfortunately graphics are needed for a companies coorporate indentity, so the first who shows to combine both of it, a good coorporate indentity without graphics, will be a famous if not a rich man.
CGI
a program which runs on web servers to enhance HTML pages and features. see java script which runs locally on the client's browser and not on the server. In fact CGI is just the protocol for the interaction between the http server and any program. Usually a perl program with the .cgi extension, but could be everything.
httpd
the http demon (process, memory resident program) on a web server.
SSI
server side includes. a statement like <--#include="header.inc"--> in a HTML doc. must be enabled by the httpd and often the extension .htmls or .shtml instead of .html. SSI docs must be parsed by the httpd at request time and are therefore not liked by webadmins but liked by web authors. With SSI you can also do some magic like calling programs, do text based web counters or include the date of the latest file update.
gif counter
trick to count access to web pages which uses horribly many resources and looks awful, better do it with SSI or better: don't do it.
admin
the administrator of a server, named "root" on unix, and "Administrator" on NT. he has all the rights you usually have on your window machine but dont have in a unix or novell network. a very special type of person: some of the nicest guys will become, once admin, nervous wracks and hyper sensible.
But he is able to sniff other peoples passwords and credit card confidentials, that's why he should be a trusted stable person (of course I'm no admin, only admin oy my nt machine, but doesn't count as long as there are not some users logging in on my machine) Always think bad of admins and always behave nice to them!
See also the Know Your Unix System Administrator Field Guide.
server
a computer which is never switched off. it allows access for clients via a network. there are server daemons for a lot of ports used by protocols such as ftp, www, telnet, news, mail, irc, ...
port
a number, i.e. 80 for www daemons "listen" on this port for news, like IRQ's in a computer
protocol
a server software, such as tcp/ip, netbeui, ipx, and also the way how some network programs communicate with each other such as ftp, telnet, mail, http, ...
demon
a memory resident program on unix-like machines. is called service on NT
webadmin
the guy responsible for the httpd, usually the site admin. sometimes the creator of the first welcome page. this can be the admin or the creative guy. You probably see the differences at once. see graphics and SSI
newsadmin
the guy responible for the news server, usually the admin of a seperate unix machine. he sets the expire for each group and is resonsible for carrying or censoring certain groups.
ftpadmin
you may guess who. he allows anonymous access, restricts the number of concurrent users and writes those cute .message files which appear at startup.
mailadmin
he's the poorest admin of all admins. usually the admin. nobody wants the be this because of sendmail, massive harddisc problems and an incountable numbers of complaint mails. But he usually reads other peoples post. see PGP
password
the string you're usually very afraid to forget if you need it. Also the string which is very welcome amongst unix hackers (or should I crackers?) to be able to do some stuff you are normally not able to do. also a string which is written on a piece of paper near your computer and is usually the name of your dog, wife, car, daughter or girlfriend. unix systems normally don't accept passwords without any special character in it. on unix systems you'll have to change your password every some months. Simply try to crack a zip with a 26 chars password and then one with any a special character (255 chars). The difference can be years. "bill" is a bad one, "1!judy&" a better one. see security Also a problem in windows+novell networks, where you have to type in both, if you dont share the same user name on both servers.
security
normally nothing you have to worry about if you're not admin, besides your password. Could be easily enhanced, if you format your drive with NTFS, and restrict other's rights. good for your private porn pictures. But beware with NTFS! You may have troubles to restore any data if there's a minor FAT or virus problem on the windows partition if it's NTFS too. see password, NTFS, ntfsdos
porn
the story of Internet success, aliases are sex, a.p.b.e.*

MS specific stuff:

OCX
compiled OLE module (program),
DDE
Dynamic Data Extension, enables magic keystrokes in other applications

Dynamic Link Library, shared library in opposition to static libs. functions in .dll (or also .arx, ...) files which are loaded and executed at run-time, may be shared amongst other applications (hopefully).
winhelp
a windows help file, with the .HLP extension
