AutoDrive operates in two modes: Arc and Bearing. Both are controlled from a floating dialog that allows the user to adjust various parameters.
In Arc mode Autodesk Vehicle Tracking calculates a path, consisting of circular arcs, through target points specified by the user. In doing so it automatically generates any transitions necessary between segments.
In Bearing mode, Vehicle Tracking turns the vehicle as quickly as possible, subject to the allowable lock rate, until the steered wheels are on a bearing through the target point, and then continues on that bearing until the selected path point reaches the target.
