I'm trying to place a gable roof over my front door that is recessed from the exterior wall. I've tried designating the roof over this wall as gable. Also I've tried the gable tool where you draw the line on the existing roof line to create gable in that spot. Neither is working. I've tried to make a gable using the plane tool but not skilled enough to figure it out. I am using home designer pro 2020. I want the gable to extend out as far as the gables at the ends of the house do. Basically I'm trying to create a covered porch. The gable in the picture was created by the roof plane tool but is incorrect because of height the edges are angled and won't join with existing roof. I've tried watching many videos online too, but still can't get it. Thanks.
