Although the history of AutoCAD predates the personal computer and the Internet, it was designed to be the first truly network-connected application. While the first commercial networked CAD applications were of the two-way type, meaning both users could interact with each other on the network, early users would also write messages back and forth with other users who were connected to the network. AutoCAD’s early networking was what is known as peer-to-peer, meaning the users are working together on the same drawings.
As of 2019, AutoCAD is still the most popular commercial 2D drafting application, with over 8 million users.
Early History
The first commercially available product to help users create drawings is Autocad AutoCad, a 2D drafting program released in 1982 as Autocad for the Tandy Radio Shack Color Computer. This first AutoCAD application was considered a revolutionary product at the time, because it was the first network-connected program available to the public. This application also revolutionized the industrial design process, due to the ability to access the drawings and data from all around the world.
The Tandy company gave away an additional, non-networked version of AutoCad AutoCad for the TRS-80, the Tandy Corp. Model I, which was an 8086 microprocessor-based computer with a built-in keyboard and printer, but no monitor. The TRS-80 version of AutoCad was compatible with both the TRS-80 Color Computer and the Tandy TRS-80 Model I computer. It was also backward compatible with the 3270-compatible early versions of AutoCAD.
The creation of AutoCAD was not part of any company plan, but was developed by Bob Wallace, a graphic artist who worked for Tandy Corporation in California. He was working on a visual drafting program for the TRS-80 Color Computer when he invented a new type of plotter that used no paper.
At the time, this was a revolutionary concept. Prior to the advent of the computer, drawing programs were very expensive. A typical drawing on paper could cost anywhere from $1,000 to $10,000 dollars. However, Wallace’s prototype with no paper plotter cost around $600.
Wallace was hired by Tandy to create a commercially available software package. He contacted Autodesk to see if they had any interest in the idea of a networked program. When

AutoCAD also exposes its command set to other applications via COM or.NET. It is possible to call AutoCAD from Delphi or Java. AutoCAD also supports many third party.NET controls and plug-ins and can communicate to other applications using.NET Remoting.
Technical information
AutoCAD features an underlying object model known as the ObjectARX library, which is similar to Delphi’s Component Object Model. All software applications produced by Autodesk use the ObjectARX library.
The Autodesk Graphical Data Format (GDF) is an XML-based file format that can be read by AutoCAD and other AutoCAD software. It was originally developed by MOBotics for the AutoCAD programming API, and then Autodesk acquired the rights to use it, and made it a part of the AutoCAD programming API as Autodesk Graph Data Format (AGDF). This technology is also available for the non-graphical applications of AutoCAD, such as the DGN (Drafting), DWG (Drawing), and PDF (Portable Document Format) formats. As of 2015, it is available as part of the Autodesk Forge.
AutoCAD also exposes C++ class libraries for programming, which are also implemented using ObjectARX. These are known as AutoLISP, Visual LISP,.NET, VBA, and ObjectARX.
AutoLISP was introduced in AutoCAD in 1985, is an Application programming interface based on LISP. It allows programmers to use the MEL (Multiple External Language) scripting language for applications and scripts. Some versions of AutoCAD include a full environment for MEL (AutoLISP), and some support limited features.
The benefit of the AutoLISP language is that it allows users to create an unlimited number of interfaces and macros, and to customize the application for their own specific needs.
Visual LISP
Visual LISP is a Visual BASIC script engine based on LISP.
ObjectARX is the underlying object model for the software, and this allows the Autodesk Graphical Data Format (GDF) to be used for importing and exporting drawing information.
File types
AutoCAD uses its own file format, and it is backward compatible with the old 2D DWG format.
