Get all families from list of documents

I have a list of Revit models and I want dynamo to open then get all families loaded.
I have already figured out opening Revit models (bulk upgrading models from the past).
I can also get all families in the current project, but I can’t combine the two.

You’ll need to use python and the API to specify the document when collecting all loadable families. It’s pretty easy though. A filtered element collector should do the trick.

Thanks for the info, another reason I need to learn python.
Until then I’m working with Chat GPT to get this working.
