To number window and door tags, you enter a unique value for the Mark parameter.
- 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.
