Part TopoShape/it

Introduction
A Part TopoShape, or formally a, is a class that defines a parametric topological shape in the software. Objects in the document that show something in the 3D view normally have a TopoShape.

The topological shapes, as well as their methods, are defined by the OpenCASCADE Technology kernel (OCCT). FreeCAD uses these shapes, and builds App DocumentObjects around them.



How to use
The TopoShape is an attribute that is assigned to some App DocumentObjects. In particular, the basic object that handles these types of shapes is the Part Feature ( class).
