Adding Cupla affects entire plan

Bob,

Thanks for the 2D jpeg. You didn't say what the ceiling heights were, or what the main roof pitch was...so I guessed.

I think my dimensions are pretty close to yours, so I added all the interior walls too. Roof problems (just like yours) appeared
only when I tried to pull up the interior walls of the cupola so they wouldn't hang down in the open ceiling of the interior.
This happened because I didn't turn off 'auto build roof '. The floor heights then climbed, and so did the walls and the roof.
The windows and vents went up in the air ( I think it's because their 'floor to top' setting doesn't change).
So, I still think all the crazy roof problems relate to floor and/or ceiling heights.

I did the middle cupola on floor 2, and had more problems with it than with the other 2, which I built as floor 3.
Keep raising the ceiling height until you see the cupola.

Looks nice. Not working on it any more until I hear back from their board. HOW DID you get or where did you get the columns? I think in the end they are looking for a "NICER" column and I am experimenting using shapes and modifying?
