AutoCAD
AutoCAD is a CAD software application for 2D and 3D design and drafting, developed and sold by Autodesk, Inc. Initially released in late 1982, AutoCAD was one of the first CAD programs to run on personal computers, and notably the IBM PC. Most CAD software at the time ran on graphics terminals connected to mainframe computers or mini-computers.
In earlier releases, AutoCAD used primitive entities — such as lines, polylines, circles, arcs, and text — as the foundation for more complex objects. Since the mid-1990s, AutoCAD has supported custom objects through its C++ API. Modern AutoCAD includes a full set of basic solid modeling and 3D tools, but lacks some of the more advanced capabilities of solid modeling applications.

Nutrition Assistance for Puerto Rico is a federal assistance nutritional program provided by the US Department of Agriculture (USDA) solely to the Commonwealth of Puerto Rico, a territory of the United States. It provides over $1.5 billion in supplemental economic resources to help just over 1 million impoverished residents cope with their nutritional needs. Since its inception in 1982, the program has been providing low-income families living in Puerto Rico with cash benefits used for food purchases. It is a collaborative effort between the USDA and the island's government, where the former provides annual federal appropriations for the Puerto Rico government to distribute individually among eligible participants. Although the methods of providing such benefits have changed over the years, the program's basic objective of helping low-income families meet their nutritional needs has remained constant. It has, however, been controversial throughout its existence. Federal reviews and assessments have revealed deficiencies in its operations and management, requiring the implementation of various changes, including increased scrutiny. It has also attracted both criticism and advocacy from Puerto Rico and the United States over its effectiveness in helping poor families and its impact on Puerto Rico's social classes and economy.

AutoCAD supports a number of application programming interfaces (APIs) for customization and automation. These include AutoLISP, Visual LISP, VBA, .NET and ObjectARX. ObjectARX is a C++ class library, which was also the base for products extending AutoCAD functionality to specific fields, to create products such as AutoCAD Architecture, AutoCAD Electrical, AutoCAD Civil 3D, or third-party AutoCAD-based applications.
AutoCAD's native file format, DWG, and to a lesser extent, its interchange file format, DXF, have become de facto standards for CAD data interoperability. AutoCAD in recent years has included support for DWF, a format developed and promoted by Autodesk for publishing CAD data. In 2006, Autodesk estimated the number of active DWG files to be in excess of one billion. In the past, Autodesk has estimated the total number of DWG files in existence to be more than three billion.
AutoCAD currently runs exclusively on Microsoft desktop operating systems. Versions for Unix and Macintosh were released in the 1980s and 1990s, but these were later dropped. AutoCAD can run on an emulator or compatibility layer like Virtual PC or Wine, keeping in mind the performance issues that can arise when working with 3D objects or large drawings.
AutoCAD and AutoCAD LT are available for German, French, Italian, Spanish, Japanese, Korean, Chinese Simplified (No LT), Chinese Traditional, Russian, Czech, Polish, Hungarian (No LT), Brazilian Portuguese (No LT), Danish, Dutch, Swedish, Finnish, Norwegian and Vietnamese. The extent of localization varies from full translation of the product to documentation only.
AutoCAD LT
AutoCAD LT is a "scaled down" version of AutoCAD. It costs less (approx. $900 USD versus around $4,000 USD for the full AutoCAD). It is also available for purchase at computer stores, unlike AutoCAD which has to be purchased from an official Autodesk dealer. It was developed so Autodesk could have an entry-level CAD package available to compete in that price class. Today AutoCAD LT is marketed as a CAD package for those who only need 2D functionality. Compared to the full edition of AutoCAD, AutoCAD LT lacks several features. Most notably, it has no 3D modeling capabilities (though it has a full suite of 3D viewing functions for looking at 3D models created in other CAD packages) and does not include any programming interfaces, such as support for most 3rd party programs and does not support LISP programs. A full listing of differences is on the Autodesk website. AutoCAD LT originated by taking the codebase of AutoCAD and commenting out substantial portions, which allowed AutoCAD and AutoCAD LT to be developed simultaneously.
Student Versions
AutoCAD is licensed at a significant discount over commercial retail pricing to qualifying students and teachers, with both a 14 month and perpetual license available. The student version of AutoCAD is functionally identical to the full commercial version, with one exception: DWG files created or edited by a student version have an internal bit-flag set (the "educational flag"). When such a DWG file is printed by any version of AutoCAD (commercial or student), the output will include a plot stamp / banner on all four sides. Objects created in the Student Version cannot be used for commercial use. These Student Version objects can and will 'infect' a commercial version DWG file if imported.
Vertical programs
Autodesk has also developed a few vertical programs, sometimes called Desktops, for discipline-specific enhancements. AutoCAD Architecture (formerly Architectural Desktop), for example, permits architectural designers to draw 3D objects such as walls, doors and windows, with more intelligent data associated with them, rather than simple objects such as lines and circles. The data can be programmed to represent specific architectural products sold in the construction industry, or extracted into a data file for pricing, materials estimation, and other values related to the objects represented. Additional tools allow designers to generate standard 2D drawings, such as elevations and sections, from a 3D architectural model. Similarly, Civil Design, Civil Design 3D, and Civil Design Professional allow data-specific objects to be used, allowing standard civil engineering calculations to be made and represented easily. AutoCAD Mechanical, AutoCAD Electrical, AutoCAD Civil 3D, and AutoCAD Map 3D are other examples of industry-specific CAD applications built on the AutoCAD platform.

AutoCAD LT
Where did this story about AutoCAD LT meaning "AutoCAD Laptop" come from? --jpgordon???? 04:02, 7 June 2006 (UTC)
Actually it means "Latest Technology"
* According to whom? It certainly wasn't any "latest technology"; AutoCAD LT consisted of the main AutoCAD codestream, with lots of parts commented out. From what I can tell, the name "LT" preceded any meaning assigned to the letters. --jpgordon???? 23:57, 21 June 2006 (UTC)
According to AutoDESK. I used to work for a dealer and when LT first came out I was attending "CAD CAMP" in San Rafael and was told on many ocassions that we were not to refere to LT as "LITE". It meant "Latest Technology". And in the beginning of the LT development there were several commands that were not implemented into the flagship AutoCAD product. Remember, back then the products were not on a development cycle that we have today (every spring we get a new release).
* Well, we'll need better documentation of that. I've asked one of my colleagues from Autodesk (the one who actually deprogrammed LT) for his recollection. I seem to recall that the "Latest Technology" was something of a hoax to give the name some meaning, rather than "just a name" -- becuase it really DID mean "light", because that's what it was. --jpgordon???? 15:58, 22 June 2006 (UTC)
Not to get into an argument with you here, but there were several commands that were in the LT version before they were in AutoCAD (full version). ie: Match Properties, Entity Linetype Scaling, etc. etc. etc.
Furthermore I don't believe that Richard Cunneo (the president at the time) would perpetuate a hoax in his own company and to his emense dealership network.
It is very common for software company marketing departments to engage in this kind of revisionist naming/spin control, especially if they can't get the engineering department to change the naming/version numbers/whatever due to deadlines or other technical concerns. -Ehheh 16:12, 22 June 2006 (UTC)
Cuneo wasn't president. He was senior vice president of sales. And yes, there were sometimes AutoCAD features that got released in LT because the release cycles were staggered (mostly to take the load off the QA department.) Anyway, Duff Kurland will advise me on the nomenclature issue. --jpgordon???? 16:25, 22 June 2006 (UTC)
Whale oil beef hooked. Duff says it really did stand for "laptop". That's weird. --jpgordon???? 21:32, 22 June 2006 (UTC)
Just talked with Godfrey Sullivan and he confirmed that the original meaning for LT was "Latest Technology". Godfrey would know this because he was the head of the Personal Solutions Group and they were the department to develop the "LT" release.
* Given the differing information from equally reliable sources, I think we need to leave the "original meaning" blank, then. We've got contradictory word of mouth from several sources Who Should Know (including me), none of which will stand as a verifiable reliable source. (We're probably doing original research here, too.) My memory of it was that this was during something of the "lite" craze in the early-mid '90s, and that when engineering staff first heard of it, the general opinion was "you're going to call it what??" followed by "yeah, right, LT doesn't mean Lite, we get it. Uh-huh." What I don't remember -- and Duff is busy travelling somewhere, so I can't get to him on this right now -- is where LT was actually conceived. A lot of stuff at Autodesk, at least throughout the 90s when I was there, was conceived first on the engineering side, and formal things like "what's the product going to be called" came later. In other words, Godfrey is likely right from the Official Company Point of View, Duff's memory of "Laptop" is likely right from the engineering point of view -- and I'm right that it didn't really mean a damned thing, and any meaning assigned to it is a "backronym". --jpgordon???? 02:24, 30 June 2006 (UTC)
I agree - it probably doesn't matter and could easily come out of the article completely. Nobody disagrees that it was called "LT" so why not leave it at that. I don't remember why what IBM XT or AT meant either - does it matter 30 years later? Not really. We don't need to explain it in the article. Do you remember what year LT came out? I've got a bunch of old Cadence magazines from the 1990's and maybe there's a review in there somewhere that might have a mention of what the name "officially" stood for. It's more of a curiosity now than anything else. As for the article, why don't we just take out the speculation and just call it LT? It's good to know Duff is doing well, BTW. He was always one of the good guys. Pete K 21:19, 29 November 2006 (UTC)
OK, I see now you already took it out. Cool! Pete K 21:21, 29 November 2006 (UTC)
I thought LT stood for Limited Technology as there is no LISP or 3D functionality, although Autodesk clearly used to use LT to showcase new technologies like the group manager which still is not in AutoCAD!! —Preceding unsigned comment added by 86.13.224.219 (talk) 17:34, 19 January 2008 (UTC)

I don't think "overlay programs" should be used. Or where does this comes from? Use "AutoCAD vertical's", "Software's build on the AutoCAD platform" or "AutoCAD software's" instead. 212.181.17.179 13:54, 3 September 2006 (UTC)

Added some stuff
Hello everyone. I'm here at Wikipedia editing some other articles, but I thought I'd drop by and expand a few AutoCAD items. Unless anyone minds, I'll add a little info here from time to time. Pete Karaiskos - Pete K 02:19, 30 October 2006 (UTC)
OK, somebody thinks calling blocks "powerful" expresses a POV. Is this article controversial? Is the idea that blocks represent powerful objects controversial? Blocks are probably the most powerful element in AutoCAD. Does anyone really deny this? Just curious. I think it's OK to use adjectives when they are accurate. Pete K 14:21, 30 October 2006 (UTC)
Calling anything 'powerful' sounds like cheerleading to me, and is IMO not encyclopedic in tone. Honestly, I'm iffy on the section in general, because I don't really see instancing as all that noteworthy. But I'll leave it as-is for now. -Ehheh 19:52, 30 October 2006 (UTC)
Fair enough. I changed it to "versitile". I don't know how much people would like in this article - we could cover lots of stuff here I suppose. I found a sub-section on blocks to be rather out of place in an encyclopedia too - but I thought I'd add to it in case people are interested in adding more stuff that's similar. "Blocks" seems to be a primarily AutoCAD term and that's why I thought it might be OK to talk about it. I don't know if AutoCAD "jargon" requires explanation at all.

Fixing double-redirect ("commenting" out)
In consequence of a move the link from the word "commenting" in the article leads now to a double redirect. I was going to fix it but the issue (pre-dating the move) is that the article about computer languages comment isn't particularly helpful to gather the meaning of "to comment out" for a computer newbie. So I'm wondering: would it be OK to change "commenting out" to "disabling"? In truth, I don't think we really know whether they used comments or, say, #if 0 / #endif directives :-) —Gennaro Prota•Talk 23:19, 24 December 2006 (UTC)
* Yes we do! Mostly it was #ifndef AUTOCAD_LT. But "ifdeffed out" is even more confusing than "commented out", I would think! The problem with disabling is that disabling/enabling can mean that the executable code is there, but somehow is being prevented from executing (as in a demo version of a program, for example); "commented out" does correctly indicate that the code was simply never compiled. --jpgordon???? 01:39, 25 December 2006 (UTC)

Double entry of questions, both for "DWG" and "Autocad" Wikipedia entries, which I would like to get answered: Autocad was a just-2D CAD software in the 1980th and in the 1990th ( Autocad R13 is still just-2D) a) So which was the first release of Autocad supporting 3D ? b) So which was the first time, that Autocad stored 3D information in its DWG ( and DXF ) output files ? c) Did 3D-CAD products of other companies store 3D informations in DWG ( and DXF ) files earlier than Autocad ? If so, please supply name of the product&manufacturer & date of release c) Was there a change necessary in the formats, for the turn from 2D to 3D ? d) Which was the first free/commercial DWG / DXF "viewer" applications with 3D support, and when ? It would be also interesting to document the story of DWG/DXF viewers, which slighly differs from the story of the real CAD products. hemmerling (talk) 06:20, 19 January 2008 (UTC)
