Loft in an unfinished garage in X13

[ADallas]

I have a model of a basic 20 x 20 garage on a slab with a hip roof. I was able to get the plate at 9' 4" by saying that's where I wanted the ceiling that I then said I didn't want. So far, so good.

 

I can't seem to make the right set of incantations to create a loft space. The loft is framed with 2x6 at 16", plywood above, gyp. bd. ceiling below. The ceiling is 7' 4" from the ground.

 

I used a basic interior wall to create the loft, planning to make the wall invisible later. The Loft "room" has a ceiling height of 7'4", and Roof Over This Room and Flat Ceiling Over This Room are checked. The wall's Ceiling Platform is set to Automatic. 

This is what happens when I uncheck "Roof Over This Room." It automatically unchecks "Flat Ceiling Over This Room."

If I leave "Roof Over This Room" checked, but uncheck "Flat Ceiling Over This Room," I get a similar effect, except that the curtain above the plate line doesn't have gyp. bd. on both sides.

 

I am able to make the wall invisible and insert a 4x6 post, but I still have the weird curtain above.

 

My next run at this problem will be to create a second floor level with some odd wall heights. I'll post a reply if that gets somewhere.

 

Any help from the experts would be greatly appreciated.

Actually, it turns out that I didn't want a loft--a floor level above the main floor but under the same roof. I wanted a "shelf ceiling"--a ceiling under the main room's plate line, like a plant shelf over a closet.
