Written by Martins D. Okoi

FreeCAD is a cross-platform OpenCasCade-based mechanical engineering and product design tool. Being a parametric 3D modeler it works with PLM, CAx, CAE, MCAD and CAD and its functionalities can be extended using tons of advanced extensions and customization options.

It features a QT-based minimalist User Interface with toggable panels, layouts, toolbars, a broad Python API, and an Open Inventor-compliant 3D scene representation model (thanks to the Coin 3D library).
