DWG (from drawing) is a proprietary binary file format used for storing two- and three- dimensional design data and metadata. It is the native format for several CAD packages including DraftSight, AutoCAD, IntelliCAD (and its variants), Caddie and Open Design Alliance compliant applications.
The files with the .dwg extension contain a database of 2D or 3D drawings that have been created within a CAD software. These files store design and meta data that describe the contents of the file. The .dwg format is considered to be the most widely-used format for CAD drawings.
