Roof over deck

[capitaldesigns]

Design Plan.zipI just started working on a hillside house with guest house andflat roofs. They will have a wraparound deck. The flat roof will extend over 

the decks. The client wants 10'-0" ceilings over the house and the decks. They also want the exterior doors and windows to be 10'-0" tall. This means I will to

have the bottom of the rafters around 11'-0" to accommodate the headers. The bottom of the ceiling joists will be 10'-0" and connect to the side of the headers.

I included the plan, section and a detail of the roof to wall connection.
 

I'm not sure how to get CA to frame this so I modeled it with 10'-0" ceilings and 24" deep rafters. I would then make the section into a CAD detail and modify
the details to show it correctly.

 

The problem I am having is in elevation view and 3D mode the thickness of the roof over the decks are showing 12" thick. The bottom of the rafters is showing 11'-0" above the deck. The rafter/ceiling assembly are supposed to be 24" thick and It should be 10'-0" above the deck. Inside the house the ceiling are shown correctly at 10'-0" high. I'm not sure why the roof assembly over the deck is not showing in elevation view as 24" thick.

 

Thanks,

Mike

Check the size of the SUB FASCIA. It's too small causing the fascia to be cut at that size.

Correct—if those are 14" roof joists, the sub-fascia needs to account for the soffit as if it's being fastened to the underside of the cantilevered roof framing.

Increasing the sub-fascia depth will eliminate that gap. Chief Architect can handle modern designs quite well, but the framing defaults often behave more like traditional gabled roof setups.
