Thank you for all the replies, I will try some of these suggestions.
To be clear, (as the picture might just appear sloped) I want sloped walls like the attached, but instead of a shed roof, I want a hipped roof to generate over the sloped walls (I'm not sure if that is even possible), If I use these work-arounds will the hip roof generate correctly, or will I have to do a work around for the roof planes on the sloped walls?
Thank you.
