AUTOCAD

AutoCAD is a commercial software application for 2D and 3D computer-aided design (CAD) and drafting — available since 1982 as a desktop application and since 2010 as a mobile, web- and cloud-based app marketed as AutoCAD 360. It is the most popular CAD software. It is developed and marketed by Autodesk, AutoCAD was first released in December 1982.

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.

AutoCAD is also available in variants as

• AutoCAD LT – It is the lower cost version of AutoCAD, with reduced capabilities, first released in November 1993. It is sold directly by Autodesk.
• AutoCAD 360 – Formerly marketed as AutoCAD WS, AutoCAD 360 is an account-based mobile and web application enabling registered users to view, edit, and share AutoCAD files via mobile device and web using a limited AutoCAD feature set — and using cloud-stored drawing files.
