On the WALLS AND FLOORS tab, in the Create group, click Floors, select Floor from the drop-down list to display the Create Floor window.

The functionality available for selection from Create Floor window is identical to the functionality available from the Create Panels. Refer to Create Panels, for more information, on the functionality of this window.
