LibreCAD is a free Open Source CAD program for Windows, Apple, and Linux. Our dedicated community of contributors, developers, and users provides support and documentation at no cost. LibreCAD was originally created to integrate CAM capabilities into QCad's community version. This can be used with a Mechmate CNC router. QCad CE was based on the old Qt3 library and needed to be ported to Qt4 to get additional enhancements. This was the birth of CADuntu. The project was initially known as CADuntu for a few months before the community decided that the name was too limiting. After much discussion with the community and some research on other names, CADuntu was renamed LibreCAD. The task of porting the rendering engine from Qt3 to Qt4 proved difficult. LibreCAD was dependent on the Qt3 support libraries initially. Rallaz, our master developer, completed the Qt4 porting during the 2.0.0 series development. LibreCAD is now free from Qt3 except in the 1.0.0 series.
