PartCAD

PartCAD is the first build system and package manager for CAD models and a framework for creating assemblies. It aims to complement Git with everything necessary to substitute commercial Product Lifecycle Management (PLM) tools.

PartCAD maintains information about mechanical parts and how they come together to form larger assemblies. The same parts are reused in multiple assemblies and multiple projects. And all of that is supercharged by the ultimate versioning and collaboration features of Git.
