- built-in scripting framework. FreeCAD features a built-in Python interpreter, with an API that covers almost any part of the application, the interface, the geometry and the representation of this geometry in the 3D viewer. The interpreter can run complex scripts as well as single commands; entire modules can be programmed completely in Python.
