hello,
Tag.TaggedElement does not work with Room Tags…?
The script works if those were door, windows or wall tags…
Any idea?
thanks

Can you show the entire graph and some of the inputs?
like the error said, you do not have the required type family loaded. thats why you cant tag your room 
For your first error, flatten the list first. Or play with levels of the Tag.TaggedElement node
Hi @Giovanni_Succi for this i think you don’t require a node
