122 CHAPTER 4: PLANNING THE 3COM MOBILITY SYSTEM
To adjust the scale
1 In the Edit Content page of the Building wizard, click on the toolbar.
2 Drag to create a line between two points. The Input dialog box appears.
3 Type the actual distance between the two points.
4 Click OK.
Until you adjust or verify the scale of a floor, 3WXM reminds you to do so
each time you navigate to the Edit Content page when the floor is
displayed. To stop the reminders, perform the procedure above, but
instead of typing the distance, just leave the distance unchanged, and
click OK.
Working with Layers Most drawings contain multiple layers of information. 3WXM allows you
to hide, add and delete individual layers. You also can add and remove
objects and move objects from one layer to another. For RF planning, you
can convert existing objects into RF obstacles and add new RF obstacles.
Generally, only some of a drawing’s layers contain details relevant to RF
planning. You can hide layers to simplify a drawing. 3WXM performs RF
calculations only with information in visible layers. Each drawing that you
import into 3WXM has a layer 0, which contains information that 3WXM
creates. You can hide layer 0 but you cannot delete it, and 3WXM
requires layer 0 to be visible when calculating RF coverage or performing
rogue detection. If you start one of these operations with layer 0 hidden,
3WXM displays a message offering to make layer 0 visible again.
For best performance and simpler planning, 3Com recommends that you
hide or remove unnecessary layers and remove unnecessary objects. The
Clean Layout option automatically deletes all objects that meet the
cleanup criteria, which you can modify. (See “Cleaning Up a Drawing” on
page 124.) You also can select and delete individual objects.
Hiding Layers
With the drawing displayed in the View panel of the Edit Content page
(in the Building wizard), click the checkbox in the Visible column next to
the layer name to show or hide the layer.
The following figure shows the same floor plan as the previous figure
after hiding unnecessary layers.
