A recent question prompted me to try out something, and I found out that the “Categories” node, while displaying the built-in categories and their built-in subcategories in the project, fails to display any custom subcategories that have been added through loaded families. Is there any way to display these custom subcategories?
I tried that one, but it doesn’t give the names. It just outputs Autodesk.Revit.DB.Category for each one.
I think you’re right though, it does give me the custom subcategories, as the number of items match.
