"As neither RealDWG nor DWGdirect are licensed on terms that are compatible with free software licenses like the GNU GPL, in 2008 the Free Software Foundation asserted the need for an open replacement for the DWG format. Therefore, the FSF placed the goal 'Replacement for OpenDWG libraries' in 10th place on their High Priority Free Software Projects list. Forked in late 2009 from libDWG as GNU LibreDWG project it can read most parts of DWG files from version R13 up to 2004. But as the libreDWG library is released under the GNU GPLv3 it can't be used by most targeted FOSS graphic software, like FreeCAD, LibreCAD and Blender, due to a GPLv2/GPLv3 license incompatibility. Due to this struggles in September 2013, the original project LibDWG re-forked its code from LibreDWG. A GPLv2 licensed alternative is the libdxfrw project, which can read simple DWGs."(https://en.wikipedia.org/wiki/.dwg)
