Adjusting The Scale Of A Drawing; Adjusting The Origin Point - 3Com WX4400 Reference Manual

Adjusting the Scale of
a Drawing
Adjusting the Origin
Point
If you imported a DWG or DXF drawing, you might need to adjust the
scale of the drawing because the units used in these drawings might not
have a one-to-one correspondence to meters and feet. To adjust the scale
of the drawing, you draw a line between two points of known distance
and adjust the measurement.
To adjust the scale
1 Display the floor plan in the Content panel.
2 Click on the toolbar.
3 Drag to create a line between two points. A dialog box appears.
4 In the dialog box, type the actual distance between the two points.
5 Click OK.
3WXM uses the origin point of a building to understand what is above or
below a given floor. When calculating RF coverage, 3WXM needs to
understand where MAP access points on adjacent floors are located so that
3WXM can take RF from those MAPs into account when assigning
channels.
If an imported drawing has an origin point defined, 3WXM tries to use
that origin point. Otherwise, 3WXM places the origin point in the upper
left corner of the drawing by default.
You are not required to use the upper left corner of the building as the
origin point. You can select an easily identifiable feature on all floors,
such as an elevator shaft. Or, to include additional features that are not
on the floor itself, you can extend the drawing beyond the exterior walls
by moving the origin farther up and left.
To adjust the origin point
1 Access the floor plan in the Edit Content page.
2 Drag and drop
The following graphic shows an example a floor plan with an origin point
in the upper left corner of the drawing.
