Set door marks from room numbers

Sets each door's Mark from the number of the room it opens from — a plain room number for a single-door room, and letter suffixes (101, 102-A, 102-B…) for rooms with several doors, in location order.

Saves ~15 min / plan

Try saying

  • set door marks from room numbers
  • number the doors from their rooms
  • mark doors by room number with letter suffixes

Frank reads plain language — these are starting points, not exact commands.

What Frank needs

  • Doors with a room association and numbered rooms
  • Optional: scope to certain rooms, and a separator style

Only writes the Mark — it never moves, creates, or deletes anything.

Watch Frank run this on your model.
