By default, Auto Pan moves the drawing so that the vehicle wheels are pointing directly at the center of the screen and are positioned a distance of 50% of half the screen height from the centre of the screen. This allows you space to continue the maneuver. You can set the distance from the center of the screen at which the vehicle is positioned following the pan by changing Auto Pan To Distance From Center Of Screen. A value of 0 here will position the vehicle in the center of the screen following the pan. A value of 100 will position the vehicle on the edge of the screen following the pan, where much of the vehicle may not be visible.
Auto Rotate Following Auto Pan rotates the drawing while it is automatically panned. This does not affect behaviour if you manually invoke the pan command.
Auto Rotate rotates the drawing so that the spine of the tractor unit points directly up the screen. This setting makes it easier to visualize the vehicle orientation when using the Manual Drive interface. However you can set Auto Rotate To The Bearing Of Steered Wheels if you find that more natural.
Auto Pan Following Auto Rotate pans the drawing when Auto Rotate is invoked.
In the Grips section, you can use the slider to adjust the size of Autodesk Vehicle Tracking editing grips, and select Show Grip Tips if you want to see a text prompt when the cursor is over a grip. These grip settings apply only to Vehicle Tracking grips. The grips displayed when the object is simply selected are controlled by the host CAD system settings.
Some Vehicle Tracking features, such as manually controlled secondary steering, make use of the mouse wheel. By default, in these cases we temporarily override any CAD functions that use the mouse wheel. To use the CAD function you must hold down the Control key (Ctrl). If you would prefer that the CAD system retains priority, select Hold <Ctrl> Key Down To Use Mouse Wheel.
Vehicle swept path envelopes are calculated by one of two methods. Both are optimized in different ways so, in some situations, one method can produce a better envelope for presentation than the other. Select or clear Use Alternative Swept Path Envelope Calculation to toggle between the two calculation methods.
