Is there a way to change import settings so that no blocks are created

Rhino Rhino for Windows

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?

Hello - as a sort of post-process you can try this plug-in that explodes the blocks onto either the insertion layer (default option) or with each part on its own layer (command line option).
ExplodeBlocksToLayers.rhp (14.5 KB)

Drag and drop the rhp file onto Rhino to load it up and the command is
ExplodeBlocksToLayers

-Pascal
