Is possible to get just the family types used in model?

Hi everybody!

I just start playing around with Dynamo and get some trouble in my first try. I’m trying to get every “family type” we used in our model so we can export to excel and check if some parameters are allright. I don’t know how to get just the types we used in the model, now i’m getting all the preloaded family types and the list is really large. Any idea?

Just placed family instances?

You could work backwards from collecting placed instances, like:

Thanks for the replies. I’ll try collecting placed instances.

I tried with “Collect all Familyinstance using Element Types” but I’m not getting system families sucha as walls, curtain walls,… Do you know any way to get placed system families also?
