What is a DWG file?

A DWG file is a database of 2D or 3D drawings created with AutoCAD, a professional CAD program. It contains vector image data and metadata that describes the contents of the file. DWG files are related to .DXF files, which are ASCII (text) versions of DWG files.

DWG files can be viewed on Windows using Autodesk's free DWG TrueView program. They may also be opened by other third-party applications that support the DWG format, such as CorelCAD, IMSI TurboCAD, and Adobe Illustrator.

Several variations of the DWG format have been published by AutoCAD. Since 2000, the DWG 2000, DWG 2004, DWG 2007, DWG 2010, DWG 2013, and DWG 2018 formats have been introduced. While these formats are similar, their file structures are slightly different. Therefore, third-party CAD programs may be able to open some DWG files, but not others.
