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.
AutoCAD drawing set description files are settings files saved in the DSD format, and these DSD files are also called properties files. The AutoCAD 2013 software creates and uses files appended with the .dsd extension. This application is classified as CAD productivity software, and the data in a DSD file usually consists of settings or details used for the publication of digital drawings stored in DWF formats.
