Part
The Part Module is the most powerful module in the whole of FreeCAD. It allows you to create and manipulate BRep objects. This kind of object, unlike meshes, can have a wide variety of components. Brep stands for Boundary Representation, which means that Brep objects are defined by their surfaces; those surfaces enclose and define an inner volume. A surface can be a variety of things such as plane faces or very complex NURBS surfaces.
