No DWG (from drawing) is a binary used for storing two- and three- dimensional design data. It is the native format for several packages including,,, (and its variants), and compliant applications. In addition, DWG is supported non-natively by many other CAD applications. The.bak (drawing backup),.dws (drawing standards),.dwt (drawing template) and.sv$ (temporary automatic save) files are also DWG files.

Both LibreCAD and FreeCAD both want to use LibreDWG and have patches available for supporting the DWG file format library, but can't integrate them. The programs have dependencies on the popular GPLv2 license while the Free Software Foundation will only let LibreDWG be licensed for GPLv3 use, not GPLv2. The official site.

Retrieved 3 November 2013. [Assimp's Alexander Gessler:] 'Personally, I'm extremely unhappy with their [LibreDWG's — LGW] GPL licensing. It prohibits its use in Assimp and for many other applications as well. I don't like dogmatic ideologies, and freeing software by force (as GPL/GNU does) is something I dislike in particular. It's fine for applications, because it doesn't hurt at this point, but, in my opinion, not for libraries that are designed to be used as freely as possible.' [Blender's Toni Roosendaal:] 'Blender is also still 'GPLv2 or later'.

For the time being we stick to that, moving to GPL 3 has no evident benefits I know of. My advice for LibreDWG: if you make a library, choosing a widely compatible license (MIT, BSD, or LGPL) is a very positive choice.'
