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

The project was stalled for a few years starting in 2011; this stall occurred for various reasons, including lack of volunteers, licensing issues and programmer motivation. In
