Vans Aircraft publishes a SolidWorks model of the instrument panel area for an RV-8. This is an assembly of various sheet metal, rivets and fastener comprising about 2 linear feet of the cockpit. I want to extract the instrument panel part from the assembly/. I expand the assembly and can see the particular part, but I haven't been able to isolate that part. The goal is to then add cut out extrusions for the various radios in the panel. I want to end up with an isolated part that I can send out for machining. It seems that this should be simple, but I am not seeing it.
