AutoCAD is a commercial computer-aided design (CAD) and drafting software application. Developed and marketed by AutodeskAutoCAD was first released in December 1982 as a desktop app running on microcomputers with internal graphics controllersBefore autocad training in chennai  AutoCAD was introduced, most commercial CAD programs ran on mainframe computers or minicomputers, with each CAD operator (user) working at a separate graphics terminalSince, AutoCAD was released as a mobile- and web app as well, marketed as AutoCAD.

AutoCAD is used in the industry, by architects, project managers, engineers, graphic designers, city planners and other professionals. It was supported by  training centers worldwide in.

History

AutoCAD was derived from a program that began in, and then released in  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.

The first version by Autodesk was demonstrated at the  Comdex and released that December. AutoCAD supported CP/M-80 computers. As Autodesk's flagship product, by March  AutoCAD had become the most ubiquitous CAD program worldwide. The  release marked the  major release of AutoCAD for Windows. The  release marked the ninth consecutive year of AutoCAD for Mac. The native file format of AutoCAD is .dwg. 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. AutoCAD has included support for .dwf, a format developed and promoted by Autodesk, for publishing CAD data.

Features

Compatibility with other software

ESRI ArcMap  permits export as AutoCAD drawing files. Civil 3D permits export as AutoCAD objects and as LandXML. Third-party file converters exist for specific formats such as Bentley MX GENIO Extension, PISTE Extension (France), ISYBAU (Germany), OKSTRA and Microdrainage (UK); also, conversion of .pdf files is feasible, however, the accuracy of the results may be unpredictable or distorted. For example, jagged edges may appear. Several vendors provide online conversions for free such as Cometdocs.autoCAD commonly use in all purposes.

Language

Auto CAD and AutoCAD LT are available for English, German, French, Italian, Spanish, Korean, Chinese Simplified, Chinese Traditional, Brazilian Portuguese, Russian, Czech, Polish and Hungarian, Albanian (also through additional language packs). 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.
