4In the Starting Floor Level box, specify the floor number of the first floor in the building. To start with a subterranean floor, you can specify 0 or a negative floor number.

5In the Skip Floor Levels box, specify floor numbers you want to skip. Skipping floors is useful when you want to model only certain floors in a building. To enter a list of floors, use commas to separate the floor numbers (example: 1,3,7). To enter a range, use a hyphen (example:

8-12).

6Click OK to close the dialog box.

7From the Content panel, you can also change default values for floors in the building. In the Unit of Measurement list, select Feet or Metric. If you are importing a drawing of a floor plan, choose the measurement system the drawing uses.

8In the Height of the Ceiling box, type the number of feet or meters from the floor to the ceiling (1 to 1000 feet or meters).

The ceiling height is based on the surface of the ceiling where the access points will be mounted, not on the center of the plenum space between floors.

9In the Ceiling Type box, select the type of ceiling used most commonly in the building.

3WXM adjusts the default attenuations based on your selection.

10To change the default attenuation for radios, type the number of dB in the 802.11a (dB) box or 802.11b/g (dB) box.

From the building’s Content panel, you can edit the properties of existing floors in the building. See “Creating or Modifying Floors” next for more information.
