Working with Seat Numbers#

With your rows placed, you can now turn on the seat number labels and verify that the numbering came out as expected. After that you will toggle on Seat Sizes, which is the visibility companion to Seat Numbers and is also a useful preview for the next step.

Step 1 — Turn on seat number visibility#

  1. On the Graphics panel of the ribbon, click Seat Numbers.
  2. Each seat now shows its seat number as model text in the plan view.

If the current view is controlled by a View Template, the application will ask whether to apply the visibility change to the template — answer Yes to update all views that share the template, or No to cancel.

For more on how this command works, see Seat Numbers.

Note

Seat Numbers and Seat Sizes are mutually exclusive. Turning on Seat Numbers automatically turns off Seat Sizes in the same view.

Step 2 — Verify the numbering#

In a correctly configured Odd-Sequential-Even layout, the numbers should follow this pattern in every row:

  • The center group runs sequentially across the row.
  • The House Left end group uses odd numbers, increasing as it moves away from the center aisle.
  • The House Right end group uses even numbers, increasing as it moves away from the center aisle.

Walk along each row from House Left to House Right and confirm the sequence makes sense. Row identifiers should also increment from front to back.

Numbers don't look right?

The most common cause is the focus point being placed on the wrong side of the room. If the House Left and House Right end groups are swapped, see the warning on Placing Your First Rows.

Step 3 — Edit a single seat number#

You can override an individual seat number directly in Revit's Properties panel. Try it on the first seat in Row A:

  1. Select the leftmost seat in Row A.
  2. In the Revit Properties panel, scroll to the Overall Legend group. The identifier parameters — including PB_Seat_Number — live in this group.
  3. Change PB_Seat_Number (for example, to 101) and press Enter.

The seat label updates immediately. The application does not validate or recalculate other seats — manual edits are entirely your responsibility. Undo the edit before moving on.

Warning

Manually edited seat numbers are not protected from later commands. If you run Replace Seats or Update Row on a row that contains manual overrides, the row will be renumbered using the active scheme and your manual numbers will be lost.

Step 4 — Turn on Seat Sizes#

Seat sizes share the same model-text mechanism as seat numbers and are useful for spotting where wider or narrower seats sit in the row.

  1. On the Graphics panel of the ribbon, click Seat Sizes.
  2. Each seat now shows its width (for example, 22") instead of its number.

This will be useful in the next step, when you replace selected seats with wider types and want to confirm the result.

For details, see Seat Sizes.

Step 5 — Toggle visibility off#

Once the model text is on, the Seat Numbers and Seat Sizes buttons on the Graphics panel only flip the subcategories that control visibility in that view (or view template) on and off. The underlying PB_Seat_Number and size data are still stored on each seat.

To turn the model text off entirely, this must be done in the Type Properties for the seat families. Alternately, the sample model includes a schedule called Seat Model Text Visibility that exposes quick check boxes to turn all model text on or off at once.
