Generates a path that follows an arc from the start position to the position of the mouse. The generated simulation uses the current vehicle (see Select Current Vehicle).

To Generate an Arc Path Simulation:

1. On the Simulation Tools toolbar, click Generate Arc Path Simulation.
2. Move the vehicle to the desired start position, and then click to set the location of the center of the vehicle's front axle.
3. Move the mouse in an arc around the front of the vehicle, and then click to set the desired vehicle start angle. The Arc Path dialog box displays.
4. (Optional) Use the Arc Path dialog box to set the options for the vehicle movement (see Arc Path Dialog Box Explained).
5. (Optional) To switch the movement orientation (reverse/forward), select or clear the Drive in Reverse checkbox, or simply click the arrow behind or in front of the vehicle.
6. Move the mouse to the desired endpoint of the section, and then click to generate the section.
7. Repeat step 6 to generate more sections until the desired maneuver is completed.
8. When you have finished creating the simulation, right-click, and then click Finish on the shortcut menu.

Note: In reverse maneuvers, only vehicles with two or fewer parts are supported.

Arc Path Dialog Box Explained

Steering Lock Angle

Displays the vehicle's steering lock angle used while generating a forward simulation.

Reverse Override

Displays the default angle used to override the vehicle's steering lock angle and articulating angle while generating a reverse simulation.

Centerline Radius

Displays the centerline radius of the vehicle's maneuver. The Centerline Radius value is dynamically updated for the current speed as the mouse is moved while generating an arc path simulation.

Design Speed

Sets the speed at which the vehicle is traveling.

Superelevation

Superelevation is considered in determining the minimum turn radius, and it is only available at speeds of 10 mph (16 km/h) or greater. To override the automatically set value, select the checkbox.

Note: In AutoTURN Online, superelevation is limited to the range of -0.1 to 0.1.

Lateral Friction

Lateral friction is considered in determining the minimum turn radius, and it is only available at speeds of 10 mph (16 km/h) or greater. Select the checkbox to override the automatically set value.

Turn Wheels From Stop

When this checkbox is not selected, the vehicle is assumed to be starting the maneuver at the speed specified. The vehicle’s lock to lock time and speed are used to create a transition in the generated path. In this transition, the vehicle’s steering wheels turn at a linear rate until they reach the angle at which the mouse position can be reached.

When this checkbox is selected, the vehicle is assumed to be starting the section from a complete stop. This allows the steering wheels to be turned while the vehicle is stopped, allowing the vehicle to proceed at a constant steering angle to the mouse position. This option is only available at very slow speeds (6 mph (10 km/h) or less), and should only be used when maneuvering space is at a premium.

Drive in Reverse

When this checkbox is not selected, the direction of the movement is forward.

When this checkbox is selected, the direction of the movement changes from forward to reverse.

Undo

Deletes the last generated section.

Finish
