Part TopoShape
Introduzione
Una Part TopoShape, o formalmente una Part::TopoShape
, è una classe che definisce una "forma topologica" parametrica nel software. Gli oggetti del documento che mostrano qualcosa nella vista 3D normalmente hanno una 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.
Diagramma semplificato delle relazioni tra gli oggetti principali del programma. La classe Part::TopoShape
è incorporata nell'oggetto Part::Feature
e da lì viene propagata a tutti gli oggetti che ne derivano.
Utilizzo
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 (Part::Feature
class).
