AutoCAD is a 2D and 3D computer-aided design (CAD) application from Autodesk, first released in 1982 and used in architecture, engineering and construction. Drawings are stored mainly in the DWG format, with DXF as an interchange format. Subscribers receive industry-specific toolsets, including architecture, electrical, mechanical, MEP, plant design, Civil 3D and Map 3D. AutoCAD runs as a desktop application on Windows and macOS and is sold by subscription; web and mobile apps let users view and edit drawings stored in the cloud.
Autodesk is headquartered in San Francisco, California, in the United States, so US law such as the CLOUD Act can apply to data held by Autodesk. For some of its cloud products, such as Autodesk Docs, Autodesk lets customers choose the primary data storage region, including the European Union; which region applies to the cloud features of a given subscription should be confirmed with Autodesk. The software is proprietary.
