As you place doors and windows in a project, you can use tags that sequentially number the elements. The tags automatically number based on the Mark parameter for doors and windows. Values can be alphabetical, numerical, or alphanumeric sequences.
- Place a door or window.
- Click Modify, and then select the element.
- On the Properties palette, enter a value for Mark.
- Place more instances of the element as desired.
All subsequent instances are numbered sequentially.
Note: All doors and windows number sequentially regardless of type. For example, you place a French door and then a single-flush door into a plan view. The French door is number 1; the single-flush door is number 2.
