2 Apply the Track Points behavior to a nonanimated shape.
The Track Points behavior inherits the animation data of the animated object closest to
it in the Layers list. (A thumbnail of the animated object appears in the Source well of
the Track Points Behaviors Inspector.)
In this example, the Track Points behavior is applied to a Bezier shape.

Track Points behavior
Note: To reference another animated object, drag that object to the Track Points behaviors
Source well or to the behavior in the Layers list.
3 In the Behaviors Inspector, choose Attach to Source from the Transform pop-up menu.
The spinning animation of the line is applied to the Bezier shape. The Bezier shape changes
form because the vertex tangents match the transformation of the source animation.
