Adjust Contour Topo Lines
The intervals between the contour lines are able to be modified by opening the layer properties page. This is done by clicking on the "Contour Topo Lines" link within the Layers panel.

The Layer properties displays a grid allowing the Min Scale, Max Scale, and Interval (feet) to be adjusted. The page will also show the current map scale for a reference.

Change the interval to increase or decrease the number of contour lines that appear on the map or change the scale to customize when they appear.

Generate a Topography Contours Map from the Map/Form list to print the data.

Contour lines can also be added to some other map templates such as the FSA Map by setting the Update Interval box to a value greater than 0.
