Hi everyone,
I’m new to rhino and i’m having issues editing an imported object from a 3d warehouse. I’m trying to use a rock from the warehouse and I wanted to use the command boolean difference to make holes on the imported rock. However it does not work. I even tried exploding the object but no luck. Can someone please advise me or let me know if is even possible to modify an imported object?

Thanks!

Hi I bet your imported object is a mesh. if you wan to make boolean operations on it you need to use another mesh objects. and the mesh boolean tools.
also there are some tools to check the integrity of the imported model for boolean operations. you can see them in the mesh toolbar.
