I was using exchange-polygonica bridge to traverse an assembly, When we have a multiPart i’m unable to get the correct Gemotry because after traversing parts, its making solid for only last part.

I was thinking to create a individual solid from each part and merge those to a single solid. Is there a way to merge the parts to single solid ?

Thnaks.
