Path Shape: A pop-up menu that lets you define the shape of the path on which the
object travels.
• Open Spline: The default shape, a straight path defined by two points at the beginning
and end of the path. You can choose to work with Bezier or B-Spline control points.
Option-click (or double-click) anywhere on the path to add points.
Use the outer control

or rectangle motion path
shape.
• Closed Spline: A closed path in which the last point is in the same location as the first
point. You can choose to work with Bezier or B-Spline control points. Option-click (or
double-click) anywhere on the path to add points.
• Circle: A simplified version of Closed Spline, in which the X radius or Y radius can be
adjusted to create a circle or an ellipse.
• Rectangle: A closed path in which the width and the height can be adjusted to create
a square or a rectangle.
• Wave: A wavy path (a sine wave) defined by two points, one at the beginning and one
at the end of the path, and controlled by the End Point, Amplitude, Frequency, Phase,
and Damping parameters.
• Geometry: The object travels along the edge of a shape or mask that is used as the
source for the path.
