Hi @clooz8
Some of the rooms was deleted from your linked model but still remains there. They can be removed from room schedule in the linked model.
I tried it again and this time it worked! Unfortunately, there were some hiccups. I deleted duplicate and not placed rooms, but for some reason, there were some rooms that didnât get the new ceiling heights. I havenât found a rhyme or reason yet. I thought maybe it was because some rooms had multiple ceiling heights, but I do have some smaller basic rooms at 79 SF that didnât change.
Glad it helped 
If you have solved your issue please mark the post as solved. Thanks!
Hi @Kulkul just a question.
It that workflow how you ensure that the space its matching with their corresponding ceiling in room?
In that workflow it seems that he didnt ensure that, no?
Sure. But here in this graph? Space maybe dont match with the correct room. Or im wrong?
In which graph? Could you please ask your queries in new topic with your complete graph, this post is already solved.
