Roof Framing Drawing Rev 2

I added two pages to my roof framing drawing to document my new dormer framing design.  I'm still not quite happy with how the dormer rafters connect with the valley rafter as shown on the last page.  To help me design the roof faster, I created a CAD model for the whole roof framing, instead of modeling each piece of wood separately and then assembling the pieces.  Tomorrow I think I will make dedicated CAD models of the dormer rafters and valley rafters and assemble them to double check I can cut the wood and assemble the parts as I want.
