Hi Doug,
Thanks for fiddling around with the roof, I appreciate your time on it. I kinda figured that to have walls raise up to the upper overlay roof, the structural cathedral roof can not lap over the top plates of the wall.
Regarding the framing, I will tweak the framing later so that it sits on the top plates of the wall. I don't want to mess around with hanging the roof framing off of the wall or getting into penetrating the wall cavity. I know how they will build it, they'll put up the 9/0 walls, build the cathedral roof, frame the overlay, then sister some studs next to the rafter seats for the sheathing attachment on the wall in question.
