AutoCAD is a commercial computer-aided design (CAD) and drafting software application. Developed and marketed by Autodesk,[1] AutoCAD was first released in December 1982 as a desktop app running on microcomputers with internal graphics controllers.
AutoCAD was derived from a program that began in 1977, and then released in 1979[4] called Interact CAD,[5][6][7] also referred to in early Autodesk documents as MicroCAD, which was written prior to Autodesk's (then Marinchip Software Partners) formation by Autodesk cofounder Michael Riddle.[8][9] The first version by Autodesk was demonstrated at the 1982 Comdex and released that December. AutoCAD supported CP/M-80 computers.[10] As Autodesk's flagship product, by March 1986 AutoCAD had become the most ubiquitous CAD program worldwide.
