observing this presentation [https://www.youtube.com/watch?v=VfE9wpIE3xA&t=2s](https://www.youtube.com/watch?v=VfE9wpIE3xA&t=2s) I’d like to understant and reply if it is possible to populate in the MEP file some information coming out from a linked ARC file by using REvit 2019 and Dynamo 2.0.2.0.

 ![erroring%20linked%20file](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/a/8/a8612ebfb42178e044af62fb1d07cf872f5c11c6.png)  
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?
