Please give me some advice.

Hi, @s0443124
Try to use this approach. I’m not sure why you need the sorted surfaces but if it is really important to you, use this.

In blue are the unsorted surfaces. In red are the sorted surfaces according the room heights.
Hope this solve your problem.
Good luck!

Thank you your advice.
I’m tryin it.
