Hello all,

I'm working on this Star Trek secondary hull, highlighted in yellow. It started out as a solid - really - but somehow along the Boolean Highway it wound up as a shell. Its hollow inside. I would like to re-solidy it, to make it back into a solid. Is there a way to do this?

Many thanks,

Bob
