do I ensure the map scale is accurate?
On the ‘Tools’ toolbar, select ‘Zoom to
small ‘Zoom to Scale’ pop-up window will appear.
In order for the reference scale to display correctly,
it is important to set the viewable screen width (in inches)
of your display monitor. Measure the exact width of your
monitor screen (in inches) and enter the appropriate screen
width value. Click on the ‘Apply’ button.
If the screen width value is incorrect for your monitor,
the displayed reference scale and map scale will not be the
same. TIP: By default, the screen width is set to 14 inches.
