Auto Cad is also popularly known as “computer aided design or computer aided drafting”. It is basically a software application for 3D and 2D design drafting. It was first developed by Autodesk, Inc in December 1982. It was the first CAD program to run on PC, notably the IBM PC. At the same time, most of the CAD program runs on minicomputer connected to a graphic computer for each user. Since the 1990s it has supported custom objects through its C++ (API). Modern Auto Cad consists of a 3D tools and a full set of basic solid modeling. With the introduction of AutoCAD 2007 improved 3D modeling, a better navigation start to work on 3D. Most importantly, it has become simple to edit 3D models. With the help of Auto Cad, now it was very much possible to do quality renderings. Now, Auto Cad are available for many languages such as German, Spanish, Korean, Russian and many more.

Mental ray engine also was included in rendering, and it was possible to do the quality renderings. The AutoCAD 2010 introduced the parametric functionality or mesh modeling. The AutoCAD supports many APIs for automation and customization and these includes Visual LISP, AutoLISP, .NET, VBA, as well as ObjectARX. ObjectARX is the C++ class library that was base for the products extending the AutoCAD functionality to the specific fields, to make the products like AutoCAD Electrical, AutoCAD Architecture, 3rd party AutoCAD, AutoCAD Civil 3D, based applications.

AutoCAD LT and AutoCAD are accessible for German, English, Italian, French, Japanese, Spanish, Chinese Traditional, Chinese Simplified, Korean, Czech, Russian, Hungarian, Polish, Danish, Brazilian Portuguese, Swedish, Dutch, Norwegian, Finnish, as well as Vietnamese. Extent of the localization differs from the full translation of a product to documentation.
