Creating domains out of the empty space of imported objects.

I am importing a Solidworks assembly using the CAD Import module.
The assembly basically has a reservoir for gas and some tubes. When I import it into COMSOL, the internal empty spaces from the assembly are not a domain. I have no idea how to convert that into a domain.
The reason I need a domain is because I want to have a line power source. I created a Bezier polygon, basically a line, just like in the cylinder tutorial in the acoustics module, and I cannot select it as a line source. Every edge of my assembly can be selected, but not the Bezier polygon. As far as I can tell, this is due to the line not being connected to any domain. It's just free-floating in the internal void of my assembly.
Now, I did try to import the assembly, subtract it from a solid block to get only the internals, but that way I need to know the exact dimensions of my part, otherwise I get left with bits and pieces of the original solid block that weren't subtracted. And if I have to look up all the dimensions, then that defeats the purpose of simply importing an assembly.
Any help would be appreciated.

Hello Thomas,
It sounds like the capability you're looking for is "Cap Faces". See my posting at this link: www.comsol.com/community/forums/general/thread/32396 .
I hope it helps.
Best,
Jeff

Indeed. I found out about that a short while after posting this. Everything works fine now. :-)
