About Drive Settings

Specify Drive settings using controls available on the Drive tab in the ribbon.

For example, you can set the location of the eye using the Eye Height and Eye Offset controls. You can also set the speed of the driving motion using the Speed control.

Changes made to the Drive settings persist while a drawing is open. When you close the drawing and open it again, or open another drawing, the Drive settings return to their defaults.

The following settings are available for the Drive command.

Eye Panel

Eye Height	This option, along with the Eye Offset option, controls the “eye” location or, center point of the view perspective, when using the Drive command. It specifies the vertical distance or height of the eye location starting from the drive path in relation to the drive path center line. The drive path is determined by the height at that location. This is a relative value, based on the level of the selected drive path at a given (each) chainage of the drive path.
Eye Offset	This option, along with the Eye Height option, controls the “eye” location or, center point of the view perspective, when using the Drive command. It specifies the horizontal distance or offset of the eye location starting from the center line of the selected drive path.
Show Eye Path	Shows or hides the eye path when the Drive command is launched.

Note: The default values for Eye Height and Target Height are controlled by the Stopping Eye Height and Stopping Object Height items in the Profile Creation collection in the Profile Edit Feature Setting dialog box.

Navigate Panel

Play\Pause	Starts or pauses the moving display of the view along the drive path.
Start Chainage	Moves the view to the start chainage of the drive path. However, if you are viewing in reverse mode, clicking Start Chainage brings you to the end chainage of the drive path.
Previous Chainage	Moves the view to the previous chainage along the drive path.
Increment	Sets the increments that the view moves through during Drive mode.
Next Chainage	Moves the view to the next chainage along the drive path.
End Chainage	Moves the view to the end chainage of the drive path.
Go To (Current Chainage)	Displays the current chainage being displayed and lets you select a chainage to move to from a drop-down list.
Speed	Specifies the speed of the motion during Drive mode.
Visual Styles	Specifies the visual style used when using the Drive command.
Loop	Sets the play mode to display in a continuous loop.
Reverse	Displays the view along the drive path in the opposite direction.

Target Panel

Target Height	Specifies the Y-axis location of the target object, in relation to the drive path center line. This is a relative value, based on the level of the selected drive path at a given (each) chainage of the drive path. The target object is a vertical cylindrical-shaped object that can be displayed or not displayed using the Show Target option. The top of the target object is always at the middle center of your viewpoints when using the Drive command.
Target Offset	Specifies the X-axis location of the target object, in relation to the drive path center line. This is a relative value, based on the level of the selected drive path at a given (each) chainage of the drive path.
Target Distance	Specifies the distance that the target object is displayed from the eye of the driver.
Show Target	Shows or hides the target object at the target location.
