poncelet posted a topic in Q&AI have been modeling my existing house with Home Designer Pro. Today, I used these instructions to create a manual dormer in a room. It worked just fine! The dormer extends right to the exterior wall, and is covered with a gable roof. (See the attached image from my plan for the dormer setup.) However, when rendering the room, the finished ceiling doesn't extend out through the "skylight" hole in the roof. (See attached rendered example.) I can see through to the underside of the gable roof panes, but I'd rather see the finished ceiling there. Is there a way to extend the ceiling into the dormer space?
