By default, Design does not create a new Elevation when you double-click on the same placement zone more than once.
If you prefer to duplicate the same elevation, as shown in the following figure, choose from the following options:
- In the ROOM LAYOUT ribbon, in the Views group, click the Add Elevation icon.
OR
- Unselect the Select existing elevation on double-click check box in the Walls/Construction Lines pane of the preferences dialog box.
