What is a DWG file?
Autodesk AutoCAD is a robust CAD application that architects, engineers, and other construction and design professionals use to create 2D and 3D technical drawings. By default, AutoCAD saves users' drawings as DWG files. Also, many other applications allow users to export technical drawings as DWG files since AutoCAD is a leading CAD program.
Variations of the DWG format
Over the years, AutoCAD has used several variations of the DWG file format. For example, since 2000, the program has saved users' files in the DWG 2000, DWG 2004, DWG 2007, DWG 2010, DWG 2013, and DWG 2018 formats, all of which use the .dwg file extension. While these formats are similar, their file structures differ slightly. Therefore, some third-party CAD applications may be able to open some DWG files but not others.
