Vehicle Path Tracking
This command traces the wheel paths
for vehicle dimensions along a centerline. The centerline is
defined by a polyline which must be created before running this
command. The front axle follows this centerline based on the path
settings from the Path tab. After specifying the vehicle dimensions
and draw options in the command dialog, the program prompts for the
centerline polyline and then draws the paths.

For the vehicle settings, pick on the Vehicle Tab. These are the
set of dimensions for the vehicle and separate layers for the
vehicle points to track.
