Dormer cheek construction

[Jtbrown]

Hi, I'm going to be converting my loft later this year. I've got 2D plans from my architect which give a good overview but they're lacking on how the dormer is framed. I'm teaching myself SketchUp and having a go at drawing the loft in 3D. I figured it'd help me understand how it's going to be built, and with ordering materials.

I've been looking at images of other dormer constructions but I can't find anything that clearly shows how the dormer cheeks are constructed.

How do you stud the dormer cheeks, should I run a diagonal timber from ridge to wall plate and build up from that? If that's the case how do you tie the stud work into the rafters?

Appreciate any help!

What did you end up doing just out of interest, having something similar done.

Did you end up figuring it out?
