Goods and bads: OCCT 7.0.0 vs OCCT 6.8.0

Is there a way to get a non-manifold shell with OCCT 7.0 or 7.1 ?

Via python I think it can be created. I think if you run faces through BooleanFragments first, then re-pack them into a shell using Part.Shell(compound_of_faces.Faces), it will create a non-manifold shell. I don't think it is doable with gui only, so far.

Code: Select all

Part.show(Part.Shell(App.ActiveDocument.Fusion.Shape.Faces))

I tried to do the same for getting a huge wire. The aim is a wire which has all edges connected. Attached the file and the command. I got an error ...

Code: Select all

Part.show(Part.Wire(App.ActiveDocument.BooleanFragments.Shape.Edges))

Code: Select all

>>> Part.show(Part.Wire(App.ActiveDocument.BooleanFragments.Shape.Edges))
Traceback (most recent call last):

Wires are quite a bit more troublesome, because order is important. I'm not sure if non-manifold wires are supported by OCC in general...
