I work for a firm that does a lot of facilities with large vaulted lobbies. Many of these areas have multiple slopes or angles in the room. My suggestion is to add a feature where you can have multiple slopes in a single ceiling so that it is seamless, just like a roof. I also think that the feature of being able to use the full version to manipulate individual points within the ceiling so that you can make it a variable structure would also help. This comes to play in areas with coffered ceilings or again spaces that have multiple slopes going to possibly a higher elevation of a flat ceiling in the same space.
