I just upgraded to Architect version of Home Designer, largely to take advantage of pony walls.

I have a large living room that has a raised ceiling - but two walls extend under into kitchen and dining.

Oddly, molding seems to be by room - not by wall. So if I assign molding for the two outer walls, I see the molding in the room divider walls (open space).

Is this a bug?  Or how can I set molding correctly on walls facing exterior but not on room divider walls?  

Also wrt molding - how do you set say a 2' stone facade on exterior walls at base? Do you use molding also?  I've tried it, I have to create an exterior room with dimensions - is there a better way or do you use pony walls for all exterior to do that?
