Is there a way to export an assembly as a solid but hide the interior?

Hello,

I have a need to export an assembly as a solid so the user can can import it into their software package. The catch is that the user cannot have see the interior parts.

Example: enclosure with multiple connectors protruding from one face. The enclosure if filled with proprietary products/designs. The customer needs a solid model to import into their design that would represent the 3D shape/footprint. I was hoping to find a feature that would fill the 3D cavity or something like it. Any ideas?

Thanks,

Craig
