From what I can see here: https://github.com/DynamoDS/Dynamo/issues/6151 here: https://forums.autodesk.com/t5/autocad-mechanical-forum/no-current-bulletin-board-exists/td-p/5465286 and here: What is NO_CUR_BB -- no current bulletin board exists?
no one seems to know the error, how to reproduce it reliably, nor how to fix it? For the geometry failure on the floors, I have no clue either but I would double check each floor individually to see which one is giving the error.
