AutoCAD is a software application for computer-aided design (CAD) and drafting. The software supports both 2D and 3D formats. It is developed and sold by Autodesk, Inc. and was first released in December 1982 following the purchase of the first form of the software by Autodesk founder, John Walker.

AutoCAD is Autodesk’s, flagship product and by March 1986 had become the most ubiquitous microcomputer design program in the world, utilizing functions such as “polylines” and “curve fitting”. Prior to the introduction of AutoCAD, most other CAD programs ran on mainframe computers or minicomputers, with each user’s unit connected to a graphics computer terminal.

AutoCAD software is now used in a range of industries, employed by architects, project managers and engineers, amongst other professions, and as of 2012 there had been 1000 training centers established across the world to educate users about the company’s primary products.

AutoCAD and AutoCAD LT are available for English, German, French, Italian, Spanish, Japanese, Korean, Chinese Simplified, Chinese Traditional, Russian, Czech, Polish, Hungarian, Brazilian Portuguese, Danish, Dutch, Swedish, Finnish, Norwegian, and Vietnamese. The extent of localization varies from full translation of the product to documentation only. The AutoCAD command set is localized as a part of the software localization.
