Category.ByName gives wrong elements

[eklund.rickard]

Hello
I like to collect Ceilings with Category.ByName. The node gives me analytical surfaces?

[sovitek]

try with the buitin categori “OST_Ceilings” a well known issue or categori by id

Thank you. I used a python script to collect all elements and filter out the ceilings since I needed the Custom Selection node.

Collecting all elements will eventually be unbearable for your DYN’s speed. I suggest looking at the previous threads where this came up.

Lines Category in Dynamo for Revit 2023 and later

Just use the category by id operation. This was discussed previously here:

Thanks Sovitek! Built in category worked!
