DWG, AutoCAD DWG Drawing (.dwg)
The .dwg file format
DWG -derived from ‘drawing’ is a patented binary file format that stores design data in 2D and 3D as well as metadata (data that describes other data). A number of CAD packages including AutoCAD, Caddie, IntelliCAD, DraftSight and Open Design Alliance compliant applications use DWG as their native format.
.dwg technical details
DWG files use binary coding to store vector image data and metadata. Vector image data on its part instructs the CAD software on how to display the DWG image. Metadata can contain information about location and client data. DWG files created with the AudoCAD 14 increase validation abilities using a file verification checksum to help in data validation. Other related features include Autodesk DWG TrueView software whereby users can view DWG files (under freeware licensing), although this does not extend to DWG TrueConvert software. Autodesk Design Review software -also free- allows users to open DWG files and take advantage of the measure and markup, sheet set organization, and status tracking features. DraftSight enables users to create, edit, and view DWG files.
