Tagging Fire Dampers

Hello everyone, I have an issue with tagging fire dampers if anybody can help, that would be appreciated. The script is ruing fine. the issue is when I add ducts to the model and run the script again, it tags the newly created dampers and untags the dampers that are created in the first script run. The script filters out the ducts that already have fire dampers in them. thanks all, [image]
