LibreCAD is a free Computer Aided Design (CAD) application for 2D design. It works on Linux, Mac OS X, Unix and Microsoft Windows operating systems.[1][2]

LibreCAD was developed as a fork of QCad Community Edition. The GUI of LibreCAD is based on Qt4 libraries, so it runs on several platforms in the same way.[3][4]

Most of the interface and handle concepts are analogous to AutoCAD, making it easier to use for users with experience of this type of commercial CAD application.

LibreCAD uses the AutoCAD DXF file format internally for import and save files, as well as allowing export to many other file formats.

GPLv3 vs GPLv2 controversy[edit]

As the GNU LibreDWG library was changed to GPLv3 it can't be used anymore by LibreCAD (and FreeCAD) [5] as both licenses are incompatible.[6] A request also went to the FSF to relicense GNU LibreDWG as GPLv2, which was rejected.[7]

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.
