RoomTagger

The write-back sibling to RoomInventory's report: runs the same point-in-room test, but instead of just counting, batch-writes the room's number and/or name onto a text parameter you choose on every element found inside — for categories Revit doesn't auto-populate a Room field on, which covers most MEP equipment/fixtures and every line-based MEP system (ducts, pipes, cable trays, conduits never get one at all).

Key features

• Point-in-room test for point-based elements, curve-midpoint test for line-based ones (ducts, pipes, cable trays, conduits)
• Writes to any existing text parameter you name — room number and room name independently, skip either one
• Category picker defaults to the MEP set most likely to need this
• Reports elements tagged, elements outside any room, and elements whose target parameter wasn't found
