Place Rooms and Tags That Report Name, Number, and Area

The recorded clip is for signed-in members. The written steps are below.

1. Open Floor Plans → Level 1. Rooms are placed in plan views.
2. Start the Room tool: Architecture → Room (shortcut RM).
   • In the ribbon, make sure Tag on Placement is highlighted so each room gets a tag automatically.
3. Move the cursor inside an enclosed space — Revit previews the room with a blue X filling the boundary it detected.
4. Click once inside each enclosed space to place a room. Press Esc twice when done.
5. Name and number the rooms:
   1. Click a room tag's text (click once to select, once more to edit).
   2. Type the real name over Room (e.g. Studio) and the number over 1 (e.g. 101) — this edits the Room element itself, not just the tag.
6. Make the tags show area:
   1. Select a room tag.
   2. In the Type Selector, switch it to a type with area, e.g. Room Tag: Room Tag With Area — the tag now reports the computed m².
   3. If that type isn't in the list, load it: Insert → Load Family → Annotations → Architectural → Room Tag.rfa, then pick the With Area type.
7. Fix a "Room is not in a properly enclosed region" warning:
   1. Click the warning (or find the offending room — its area reads Not Enclosed).
   2. Look for the gap: an unjoined wall corner, a missing wall, or a wall whose Room Bounding property is unchecked.
   3. Either close the gap with the wall's drag grips, or draw a Room Separator line across an intentional opening: Architecture → Room → Room Separator, then sketch across the gap.
8. Delete-test: select a room and press Delete — Revit warns the room is removed from the view but stays in the project. Use Architecture → Room and pick it from the Room dropdown in the Options Bar to place it again, or delete it for good from a room schedule.
9. Check yourself in 3D or by moving a wall in plan: room areas update automatically because the room reads its bounding walls.

Note: The Room is a real model element — its name, number, and area are data that every tag, schedule, and area calculation reads from the same place, which is why you never write a room name as plain text.
