just for completition:you also could use Assign Paths from the Tree Frog plug in [assign]

I see! Thank you so much for the explanation. Everyone has been very helpful! It’s become clear to me that I need to study more. I am using this to create augmented polyhedra with variable augmentations. [image] [image]
