Thanks for the quick input. I had experimented with the roof generator but did not get the hang of it. I have tried again and get better results now. What I have not yet figured out is whether I can create the roof from one room, or whether I would need to piece it together from multiple rooms.
I am looking to generate a roof with several dormers like this: https://www.dachwerk-nord.de/gauben/schleppdachgauben/ The roof spans from mid of the 2nd floor to top of the house (3rd floor). For now It seems most practical to build the different angles separately and then group the objects in SH3D. Any experiences on how to best do this? Or perhaps someone has written a guide
Thank you!
