• Ping-Pong: The object moves along the path until it reaches the last point on the path,
then it moves backward to the first point on the path. The number of “ping pongs” is
defined by the Loops parameter.
Control Points: This parameter becomes available when the path shape is Open Spline
or Closed Spline. Click the disclosure triangle to display the Position parameters for the
motion path control points. The first value field is X, the second value field is Y, and the
third value field is Z.
Note: You cannot apply Parameter behaviors to the control points.
HUD Controls
In the HUD, the following controls are always available: Path Shape, Shape Type, Direction,
Speed, Custom Speed, Apply Speed (sets the number of times the object travels the path
over the object’s duration), and End Condition. Other parameters become available
depending on what is selected from the Path Shape parameter.

Motion Path Tasks
The following tasks show you how to customize the Motion Path behavior.
Distancing the Object from the Motion Path
By default, the object is locked to the motion path by its anchor point.
To distance the object from the path
µ
Select the Anchor Point tool from the toolbar and move the anchor point in the Canvas.
For more information on using the Anchor Point tool, see Using the Anchor Point Tool.
Note: A separate Offset parameter allows you to offset the starting location of the object
on the motion path (but does not offset the object from the path).
Moving the Object and Its Motion Path
Moving an object moves the object’s related motion path.
