Revit API BuiltInCategory naming


I am trying to learn the revit API true some easy Dynamo scipts and Marco’s.
Mostly i can find everything online. But i have alot of problems with the category’s.

For example Spaces are OST_MEPSpaces .
This one i found but for the Air Terminals i can’t seem to find.

so first question can someone please tell me what the code is for Air Terminals?
Second question, is there an easy way to find out what the builtincategory code is? For example when u click on an element?

Thanks alot!


I know this, but still the naming is not always logical for me.
I scrolled true the whole thing and still can’t seem to find the air terminals.


Great thanks alot!
