Get all elements of a revit category from a selection

Hello everybody,

I am very new in Dynamo, and i am sure that my problem has an easy solution, but I did not find it yet…

I get a multiple selection and a list with all elements. I would like to maintain all elements of a category (Air Terminals) in this list and discard the rest of categories (filter elements in a selection).

Is it possible?

Many tanks in advance!

This is doable! With a few custom nodes from clockwork and steamnodes. Welcome to the forums and to Dynamo!
