This and, to a lesser extent, its interchange file format DXF, have become de facto, if proprietary, standards for CAD data interoperability, particularly for 2D drawing exchange. The 2022 release marked the 36th major release of AutoCAD for Windows and the 12th consecutive year of AutoCAD for Mac. As Autodesk's flagship product, by March 1986 AutoCAD had become the most ubiquitous CAD program worldwide.

Introduction Ī man using AutoCAD 2.6 to digitize a drawing of a school building.ĪutoCAD was derived from a program that began in 1977, and then released in 1979 called Interact CAD, 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. It was supported by 750 training centers worldwide in 1994. AutoCAD is primarily used for 2 Dimensional drawings, and even though 3D modeling is available in AutoCAD other computer-aided design software like Fusion 360, Inventor and Solidworks are preferred in 3D modeling.ĪutoCAD is used in industry, by architects, project managers, engineers, graphic designers, city planners and other professionals. AutoCAD is also available as mobile and web apps.

Before AutoCAD was introduced, most commercial CAD programs ran on mainframe computers or minicomputers, with each CAD operator (user) working at a separate graphics terminal.

Developed and marketed by Autodesk, AutoCAD was first released in December 1982 as a desktop app running on microcomputers with internal graphics controllers.
