FreeCAD: Your own 3D parametric modeler

FreeCAD, the open source 3D parametric modeler

FreeCAD is an open-source parametric 3D CAD modeler made primarily to design real-life objects of any size. Parametric modeling allows you to easily modify your design by going back into your model history and changing its parameters. FreeCAD is aimed directly at mechanical engineering and product design but also fits in a wider range of uses around engineering, such as architecture or other engineering specialties. FreeCAD features tools similar to Catia, SolidWorks or Solid Edge, and therefore also falls into the category of MCAD, PLM, CAx and CAE. It is a feature-based parametric modeler with a modular software architecture which makes it easy to provide additional functionality without modifying the core system.
