So I am tryuing to build a curved roof on my trailer. I am following tutorial that can be find on yt. Yt tutorial don't show it on fundation and with windows but I decided to give it a try. The roof is fine unitl I save the game. As you can se on the photo the roof is curved correctly but the windows and doors are off. When I do it on second level it's the same but windows are higher. Maybe someone know a better trick for this?
