FreeCAD 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. The interface is built with Qt. FreeCAD runs exactly the same way on Windows, Mac OSX and Linux platforms.
FreeCAD Features
Rock-solid OpenCasCade-based geometry kernel, allowing complex 3D operations on complex shape types, and supports natively concepts like brep, nurbs, booleans operations or fillets
Full parametric model allowing any type of parameter-driven custom objects, that can even be fully programmed in python
Complete access from python built-in interpreter, macros or external scripts to almost any part of FreeCAD, being geometry creation and transformation, the 2D or 3D representation of that geometry (scenegraph) or even the FreeCAD interface
