There surely is a way to do it directly from the project but I still have to try it. I did something similar in this thread but I should edit the code a bit to make it work in your case

Load Family and the .rfa and all it's nested component to a new location

[nested%20families] I tested it quickly and once you are in the document of the host family you can select any element inside it with a filtered element collector.

I did not do it all in one python code to make it more intuitive here on the forum First code: doc = DocumentManager.Instance.CurrentDBDocument actually here you should i…
