LibreCAD free Open Source CAD for Windows, Mac and Linux


LibreCAD is a free Open Source CAD application for Windows, Mac and Linux. Support and documentation is free from a large, dedicated community of users, partners and developers.

LibreCAD started as a project to create CAM capabilities in the community version of QCad for use with a Mechmate CNC router.

As QCad CE was developed with the old Qt3 library, it had to be ported to Qt4 before further improvements. This led to CADuntu.

The project was known as CADuntu only for a few months before the community decided the name was inappropriate. After some discussion and research on existing names, CADuntu was renamed LibreCAD.

Moving the rendering engine to Qt4 turned out to be a big project, so LibreCAD first depends on the Qt3 support library. The transition to Qt4 was finally completed during the development of the 2.0.0 series, thanks to the main developer Rallaz.

Meanwhile, for the LibreCAD 2.2.0 series, Qt5 is required.
