Using Outlist Recursive

[JoshM]

I have a question about matching a selected face to a parent primitive shape, using Python. In this case, I was testing a Cone object using the python console--but my question is more general for Cone, Plane, Cylinder, Sphere, BSpline,Toroid, etc...

Code: Select all

OperationSelectedGeometry=Gui.Selection.getSelectionEx()[0].Object
>>> myOpSel=Gui.Selection.getSelectionEx()[0].SubObjects
>>> sel = myOpSel[0]
>>> sel.TypeId
'Part::TopoShape'
>>> OperationSelectedGeometry.TypeId
'Part::Cone'
>>> OperationSelectedGeometry=Gui.Selection.getSelectionEx()[0].Object
>>> myOpSel=Gui.Selection.getSelectionEx()[0].SubObjects
>>> sel = myOpSel[0]
>>> OperationSelectedGeometry.TypeId
'Part::MultiFuse'
>>> OperationSelectedGeometry.OutListRecursive
[<Part::PartFeature>, <Part::PartFeature>, <Part::PartFeature>, <Part::PartFeature>, <Part::PartFeature>, <Part::PartFeature>, <Part::PartFeature>, <Part::PartFeature>]
>>> 

I can then use a for loop to iterate through the parent geometry to find the cone that was used to build a fusion, cut, etc...

How do I distinguish the cone parent to the selected face? Is there a way to directly link a Face back to the primitive used in its creation?

Thanks,
Josh

Is there a way to directly link a Face back to the primitive used in its creation?

There is no interface for that, sorry. There is an experimental implementation, realthunder's topological naming. I haven't looked into it very much, but I think it must be possible to extract this face-to-face relations.

Thanks for your response DeepSOIC.
