Door signage placed from the room the door leads into — rules pick the room, the wall face and the jamb; preview the whole run before placing.
Every door has two rooms and only one of them belongs on the sign. Sign asks the door which room you are walking into, matches it against your rules — by name, number, department or any room parameter — and places the family that rule names on the right face of the wall, beside the handle or the hinge, at the height you set.
Preview the whole run before anything is written; placing is one named transaction, and doors that cannot be solved are listed with the reason instead of guessed at.
