I'm designing an addition to a rectangular house which currently has full 9/12 gables on the N & S ends. The addition will be on the E side and will also have a full gable end, but I need that to have a steeper pitch, probably 12/12. The roof planes are rendering correctly, but I can't change the pitch of that east gable. I've tried setting the pitch to both 9 & 12 using both the Default settings and the Build Roof tool, then attempted to change the pitch of individual walls. When I do that, the pitch field is inoperable but displays the word "Vertical" and the wrench icon.
I know I must be missing something, but I'm stuck. Thanks!
