Attic Trusses

[builtright3]

Hey Guy's,

I get this warning when I try to make and attic truss and Im not sure how to fix it.
I made a second floor with a ceiling hieght at 4 1/2" high so the framing will come out the way the we want it. He is doing these 4 foot eaves with a soffit returning back to the wall and so I needed more height. Everything looks good in my section but we also want an attic truss.

If anyone can help me figure this out I would much appreciate it.

Would this be a "3-story" house?

 

First floor would be your main floor; Second floor would be your little air gap you're showing; third floor would be the attic space.  You would draw the walls, ceiling, etc.. on it as if it is another floor in Chief?

 

We don't get heavy into showing framing and trusses, so not 100% it will work.  But that's how I'd do it.

This would just be to make space for the HVAC system (FAU). Its not for a room.

You didn't need to add that second floor to gain heel height.  Just raise the roof.

 

You might learn something from this video.  Check it out.  Sounds like you want a platform of sufficient size in the attic for the air handlers and supply and return trunks, so the attic might just need 5 trusses to give an 8' long deck.  You'll need to guess whether the truss engineer will do the trusses with a 2x10 or 2x12 bottom chord, but that'll all be figured at truss-quote time.  Use attic walls parallel to the trusses so you only get the attic trusses you need.
