That worked great — thanks for showing both of these techniques! I didn’t know that curves could be used for Booleans like that — I always thought it only worked with solid objects.

I used some Booleans to trim the rounded shapes, and I think that caused a lot of broken edges — tiny segments. I can join them, but whenever I separate the edges again, they split into all these little pieces.

Is there a way to merge or “Boolean” these edges together somehow, to get a cleaner model? It gets very tricky to apply a Fillet or Chamfer to these tiny bits. I’ve tried creating Closed Curves from the edge outlines, but I can’t seem to use them to generate a Fillet.

Thanks again,
