A full parametric model allowing any type of parameter-driven custom objects, that can even be fully programmed in python.

Those extensions can be as complex as whole new applications or as simple as python scripts or self-recorded macros A modular architecture that allow plugins (modules) to add functionality to the core application.A complete OpenCasCade-based geometry kernel allowing complex 3D operations on complex shape types, and supports natively concepts like brep, nurbs, booleans operations or fillets.FreeCAD runs exactly the same way on Windows, Mac OSX and Linux platforms. 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.įreeCAD is based on OpenCasCade, a powerful geometry kernel, features an Open Inventor-compliant 3D scene representation model provided by the Coin 3D library, and a broad python API. FreeCAD is a general purpose Open Source 3D CAD/MCAD/CAx/CAE/PLM modeler, 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.
