I’m trying to get the information from linked file (architectural) in order to write a dedicated plumbing fixture schedule in the end.
The Archilab node: “elements in room” shows me an error: File “string”, line 68, in AttributeError: ‘List[object]’ has no attribute 'area’

Can you help me to find a solution for mentioned above error?
thanks in advance.

try a flatten node after you collected your rooms or use list@level

Probably there are some unbounded rooms in linked file. You need to remove them or filter them out from a list.

i controlled by master file…and there are no room with 0sq area or with unbounded condition. Have you any other suggestion?
