6 In 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).

7 Click OK.

After creating a floor, you can import or draw details about the floor. See 
“Importing or Drawing Floor Details” next for more information.

You can add information for a floor by importing a drawing of the floor 
or by using 3WXM’s graphics tools to draw the floor. 

After you import or draw the floor, you need to specify the RF 
characteristics of the floor, by specifying the attenuation of obstacles such 
as walls, doors, windows, and so on. The attenuation of an object indicates 
how much the object affects an 802.11 radio signal. 3WXM uses the 
attenuation information when calculating how many MAPs you need and 
where to place them in order to provide the desired wireless coverage.

The following sections describe how to import or draw a floor. For 
information about specifying the RF characteristics of the floor, see 
“Specifying the RF Characteristics of a Floor” on page 94.

You can import a drawing of your floor plan into 3WXM. 3WXM supports 
the following file types:

„

AutoCAD drawing (DWG), a native binary format used by AutoCAD. 
You can import the following versions: R13, R14, R2000. Use R2000 if 
available. 

„

Drawing Interchange Format (DXF), an ASCII-based interchange 
format used for multi-vendor interoperability. You can import the 
following versions: R12, R13, R14, R2000. Use R2000 if available.

Graphics Interchange Format (GIF) (.gif)

3WXM cannot import files in Visio format. However, you can export a 
Visio file to a DXF or JPG file, then import that file into 3WXM.

You can also draw a floor plan in 3WXM if you do not have a drawing of 
your floor in one of the supported file formats.
