LibreCAD is a free Open Source CAD application for Windows, Apple and Linux. Support and documentation are free from our large, dedicated community of users, contributors and developers. LibreCAD started as a project to build CAM capabilities into the community version of QCad for use with a Mechmate CNC router. Since QCad CE was built around the outdated Qt3 library, it had to be ported to Qt4 before additional enhancements. This gave rise to CADuntu. The project was known as CADuntu only for a couple of months before the community decided that the name was inappropriate. After some discussion within the community and research on existing names, CADuntu was renamed to LibreCAD. Porting the rendering engine to Qt4 proved to be a large task, so LibreCAD initially still depended on the Qt3 support library. The Qt4 porting was completed eventually during the development of 2.0.0 series, thanks to our master developer Rallaz, and LibreCAD has become Qt3 free except in the 1.0.0 series.

Built-in version control and simple management tools solve the costly need for a separate PDM system. Your team and you always on the latest design data. Every modification made by every user is captured and recorded and can be reversed at any time, providing unlimited undo/redo and a documented audit trail. Branching and merging enable many product ideas to be developed in parallel. The parameterization capability is one of the most significant advantages of SolidFace, and it is present in all design steps. 3D Motion simulation is no different; the simulation is updated simultaneously with the movement. Another important capability is the simulation of 2D mechanisms, which can be performed either in 2D drawing or in 3D sketch module. Directly available through SolidFace's software interface, this new online part library features over 100 million part numbers from hundreds of leading component manufacturers and distributors and thousands of ISO, ANSI, DIN, NF, GB, ASME, and more.
