What is a Good Way to Build This Soffit?

[DRyeHD]

I've not done what I'm calling a "drop down soffit" like this before.  I can't figure out how best to build this in CA so I can apply materials as shown in the picture.  I'm sure many out there do this.  Can you give me your best process?

The soffit attaches to the sub fascia. If you have a 3/4" material for your soffit and you want a 1/4" drip on your fascia then make the sub fascia 1" less than your fascia and it will build with that look.

Howdy Damon,

 

If you trying to show that exterior wall strip below the roof, use ceiling planes.

The example in the photo looks like it uses some sort of parallel chord truss system over the patio area, just however deep you need it to be, order the truss' that size and finish appropriately. Shouldn't need to be insulated at all either, do make sure its vented though if your using a T&G finish.

As long as you have sufficient separation and sheathing @ the wall to isolate the area, make sure you detail that in there to avoid temperature difference issues etc down the road. 

 

In the program. @CharlesVolz had it bang on. Create some ceiling planes over that patio and set the height, framing should fill in with Truss / defaults / etc.

I think it's done with roof structure.  Looks like a framing depth of 20 inches or so, with a parallel chord truss.  The roof is overhanging that windowed gable wall.  The gabled roof edge has a shadow board fascia, and the finished fascia is matching siding.  You'll do that with p'line solids.

 

AFAIK, we've no way to make a fascia board have a texture to match that of a siding.

If you selected roof trusses, they will build between the ceiling plane and the roof plane. The elevation of the ceiling planes and roof planes determines the roof structure's depth.

quick n dirty method

@Renerabbittdoes that do the correct framing though? Wouldn't the "thick wall" just be really odd framing?

A quick roof & ceiling plane will actually build everything out would it not? depending on defaults etc.

yup, hence the quick and dirty, haha..talking to a GC that hasnt produced an accurate framing plan in decades..it takes too long. my details handle that, my framers handle that too, deferred truss submittals..engineers approach

one could also build a room instead, vaulted ceiling, doorway, just takes a smidge longer but will actually build the framing more accurately

@CharlesVolz that's what I was thinking.  I just needed a nudge.  @TCB_BdnMY, yes a truss system will be needed inside and out.  @Renerabbittyour quick and dirty method is quick but I want to make sure I can get the exterior materials the way I want them.

Exactly. I never met a framer that did it my way. Always their way. But always good.

Goodness I wish. For something like that where I'm at, the city would want a full tall wall framing plan and section of the front area along with the submitted truss plans etc. 
I mean, its not the worst thing, but oh well. 

Still cool to see the "quick n' dirty" solution, sometimes thats all you need.

I just handle this with details. I have a detail system that is largely automated. then callouts and big bubbles on a minimal cross section. my details stack up to look like cross sections
A lot less work then trying to get the model to behave
