Hi,
I am using Home Designer Pro 2022 but this is an issue I haven't solved in previous versions either. I am designing a square cabin with 2 push outs, and a 1 inch ceiling height second floor. The first floor has 9 foot walls. At this point everything from the roof line is as expected as seen in the attached photo. I then add a screen porch on the end of the cabin and add a roof. All fine after this step as well. However, when I go to add a flat ceiling under the porch roof the software does create the flat ceiling but I get a crease now in the main roof line as seen in the second attached image. I can't figure out how this are linked and have run out of ideas on how to fix this. Any insights would be greatly appreciated.
