Hello everyone,
I’m trying to cut an opening in a parent family using a void inside a nested shared family (inside the parent family).
I’ve tried using the Element.CutGeometry from the Clockwork package, but it didn’t work as expected. I believe this is because the family that needs to be cut and the cutting family are nested within the same family.
I tried using the node to cut with a family that was not nested and it worked, I also managed to cut the family manually in Revit.
So, what I’m trying to achieve is cutting a solid in a parent family using a void from a nested family.
Has anyone successfully done this or could suggest an alternative node/package/workflow that could make this possible?
Any guidance or examples would be greatly appreciated!
Thanks in advance!
Hey,
I thought I knew what you were doing, but this confused me… So you have a family containing some geometry… There is a shared nested family containing geometry inside it, and you want to cut the family geometry with the shared nested geometry… Is that correct?
You opened Dynamo while you had a Family opened, ran the Clockwork node on 2 bits of geometry in the family and it worked? Is that right? But not when you used the family geometry and the shared nested family geometry?
Sorry just checking

This is the method which clockwork is using, you see how it uses 2 solids…
The element must be in a project document or in a conceptual model, pattern based curtain panel, or adaptive component family. -or- The element does not meet the condition that it must be solid and must be a GenericForm, GeomCombination, or a FamilyInstance.
This is a Revit workflow issue. Revit won’t allow cutting from a void nested in a separate family, so Dynamo won’t either. Voids need to sit at the same level as the geometry you wish to cut, whether it’s in a family or in a project.
edit for clarity- a (non nested) void in family that doesn’t cut anything in the family can be used to cut project level geometry.
