Can someone take a look at the attached plan and tell me why the fascia on the curved roof extends almost to the ground? I've never really attempted a curved roof...and really have no idea what I'm doing...either right or wrong.
I'm sure it's user error...
RANCH PLAN 1.plan
I'm have a hard time trying to create the roof shown in the attached photos - one plan, one mostly elevation. This roof is on an octagonal structure. So far, I am not having much success, despite spending a lot of time playing around with the angles at eave and ridge for the curved roof plane. I know I need multiple roof planes, and have used a flat piece of roof for the first 25' or so of the roof with about a 1:12 pitch. Then I start a second roof plane that is curved. It seems that if I can get a steep enough slope up toward the ridge to match the actual roof line, then the lower part of the roof has a negative curve and goes below the first roof plane, which is no good. I'm wondering if I need to have more than 2 roof planes per segment to get this particular roof shape...
The third image is the best attempt so far, and that is with one flat roof plane and one curved plane. But I'm hoping to get closer to the actual roof. Any suggestions? This is my first time working with curved roof planes
