Able to set a Component as a Background object and set particular faces as visible, it then does not highlight when mouse is over it, and is not select-able. As you move around your design you can see your normal components through the faces not marked as visible. I have been designing a PC to sit in a corner so want the walls for placement and sizing reasons but don't want to be highlighting or picking them and want to see the back of the components through the walls if I rotate around.
