I saw a question like this on the forum so I had a quick go at it (see image below). Basically it checks what Family Types are placed against those loaded into the project, and then deletes unplaced component Families using SteamNodes Tool.Eraser:

Post flight family list:

Future versions of this could start looking at system families / types using similar methodology.

Long time reader of your blog, first time posting. What are the nodes you used for “Collect all FamilyInstance using Element Types” and “Get Family List for this project”.
