Here is a list of the major AutoCAD releases including a few selected features for each release to illustrate the growth of AutoCAD. The first shipments of AutoCAD came the next month. The history of AutoLISP is closely tied to the history of AutoCAD, so a quick survey of the development of AutoCAD is given first.ĪutoCAD was first demonstrated for the public in November 1982 at the COMDEX trade show in Las Vegas.
