When I import large assemblies from Creo using a STEP file, Rhino imports a series of nested blocks. Sometimes hundreds of them, nested 5 or 6 deep if the assembly is large.
In order to rearrange/edit/delete layers and such, I need to delete all these blocks. Since Rhino won’t let me delete a block if it is nested in another one, this is a huge hassle.
Is there a way to change import settings so that no blocks are created?
