No DWG (from drawing) is a binary used for storing two- and three- dimensional design data and. 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. Libre Graphics World. Retrieved 15 April 2015.

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.' • Prokoudine, Alexandre (2012-12-27).. Retrieved 2013-08-23.
