Ive gotten to the point that I can set up the walls and they extend the normal full height. Then I set the roof plane and get that on top of those full length walls. I can then manually lower those walls, but not matter what I do I can't get the roof plane to move down with it.
Using those instructions for a wall dormer, the issue starts when drawing the walls- they are full height. I do check the box for them to be cut at roof height. What setting am I missing to get the roof to tie into the peak of the roof and lower the walls to match?
