After importing a new contour
map, a setting screen, as shown in Figure 2(a), can be accessed through Road Design option under Settings menu
to specify the road design settings, including unit, speed limit, grade limit,
maximum cut and fill, and so on. The scanned contour map parameters (image
resolution and map scale) can also be specified by clicking on the Contour Image option under the Settings menu, Figure 2(b). Please leave
the settings as default for the tutorial example and click “OK” to close the
design settings window.
