Hi guys,

I am trying to write a script that is supposed to tag all doors in a project based on a selected family type and then center it in the middle of the door leaf.

I have started a script that will take the location of the annotation symbol highlighted above. I have used the Archi-lab package (create annotation node) however it is not working. Does anyone know why?

Also, I am not sure how to go above centering the annotation symbol once it is placed. Does anyone have any ideas about doing this?

Hi @dobbst01,

You need as many points as elements.  
Connect Element.GetLocation to AllelementsOfCategory node.
