Eric, I've been working on this on and off for the past several days and the struggle continues. I have managed to get as far as "pull the roof over the dormer". I can't for the life of me figure out how to do that. I am assuming I need to use the break tool but no matter what I do I don't get anything but the entire edge of the upper roof plane.
LawB10, thanks for your approach. I have been trying to work out Eric's approach on my own but I am starting to feel like no matter what I do I may never get the hang of this software. I am about ready to take the plan you provided and use it as a starting point and make some modifications to it to get it where I need it to be.
I have been using 2D cad programs for over 30 years but this one always gets me at what seems like should be simple things. I can get 90 percent of what I want to achieve but the last 10 percent stops me cold. I also have a pretty good grasp of Sketchup and could probably have done most of this in that in far less time.
You guys make it look easy but I feel like pulling my hair out sometimes. I guess I need to just spend some time experimenting with this without the pressure of an actual project getting in the way.
