Roof & Cathedral Ceiling Problem

[ghlabarge]

Hello,

I've ran into a problem trying to do a cathedral ceiling over my great room. I'm relatively new to the software, but I'm picking things up pretty quickly.

The pictures show what I'm trying to do better than words. In short, I'm trying to have a gabled roof cathedral ceiling in part of the house with a shorter gable roof that is covered by a larger gable roof. I want the rest of the rooms to have a normal ceiling on them.

Using Home Designer Suite 2014.

Any help would be great.
