Room numbers follow creation order, not the plan. Then the client moves a wall. Here is the manual way, the Dynamo way, and the one-click way.
Select each room, type the number in Properties, repeat. Revit warns about duplicates as you go, so you end up using temporary numbers (“x101”) and doing it twice. For 8 rooms it is fine; for 180 it is the afternoon.
Collect rooms, sort by location X/Y (or along a spline), write Number. Works well if someone maintains the graph and remembers that sort-by-Y needs a tolerance band or rooms in the same row shuffle.
Tags read the room's Number parameter, so they update instantly.
Hub writes in one transaction with temporary values first, so Revit never sees two rooms with the same number mid-way.
