of 0.5 ft. (0.15m). The inner and outer height offset can be used to
raise or lower a track relative to the track adjacent to it. For exam-
ple, a curb track might have a Track Inner Height Offset value of
0.5 ft. (0.15m) to create the face of the curb, while the Track Outer
Height Offset would be 0 so that the next track (perhaps a side-
walk) would be flush with the top of the curb.

fIgure 5.18 An example curb track
track surfaces You can assign materials to the top, inner, and
outer surfaces of a given track. The materials must come from the
material group that is assigned to the road style.
driving Lanes In the lower-right corner of the Track Settings
section of the configuration dialog for a road style, you will see the
#Forward Driving Lanes and #Backward Driving Lanes settings.
These values determine how many times the first track in a group
(usually a lane) is duplicated.
track Icons In the lower-left corner of the Track Settings dialog
you will see a series of icons used for managing tracks. Working left
to right, the first and second icons are used for adding and removing
tracks, and the third is for duplicating tracks. The next two arrow
icons are for setting the order of the tracks. The road will be built by
arranging the tracks in the order shown, working outward from the
centerline. So, you would want to list lanes, then curbs, and then
sidewalks, for example. The last button will create or remove the Left
Group, enabling you to control whether the road is symmetrical.
