Part TopoShape
Introduction
Part TopoShape ou officiellement Part::TopoShape
est une classe qui définit une topological shape (forme topologique) paramétrique dans le logiciel. Les objets dans le document qui montrent quelque chose dans la Vue 3D ont normalement une TopoShape.
Les formes topologiques, ainsi que leurs méthodes, sont définies par le noyau de technologie OpenCASCADE (OCCT). FreeCAD utilise ces formes et construit App DocumentObjects autour d'eux.
Diagramme simplifié des relations entre les objets centraux du programme. La classe Part::TopoShape
est incorporée dans l'objet Part::Feature
et à partir de là, elle est propagée à tous les objets qui en sont dérivés.
Utilisation
Part TopoShape est un objet attribué à certains App DocumentObjects.
In particular, the basic object that handles these types of attributes is the Part Feature (Part::Feature
class). All objects derived from this class will have access to a Part TopoShape.
Some of the most important objects with Part TopoShape are the following:
- Any primitive solid created with the Part Workbench.
- Any PartDesign Body and PartDesign Feature created with the PartDesign Workbench.
- Any object derived from Part Part2DObject, like most objects created with the Draft Workbench.
- Any sketch, that is, Sketcher SketchObject, created with the Sketcher Workbench.
- Primitives: Box, Cylinder, Sphere, Cone, Torus, Tube, Create primitives, Shape builder
- Creation and modification: Extrude, Revolve, Mirror, Scale, Fillet, Chamfer, Make face from wires, Ruled Surface, Loft, Sweep, Section, Cross sections, 3D Offset, 2D Offset, Thickness, Projection on surface, Attachment
- Boolean: Make compound, Explode Compound, Compound Filter, Boolean, Cut, Fuse, Common, Connect, Embed, Cutout, Boolean fragments, Slice apart, Slice, XOR
