Looping Splines
It is often useful to repeat an animated section, either infinitely or for a specified number of
times, such as is required to create a strobing light or a spinning wheel. Fusion offers a variety
of ways to repeat a selected segment.
The various Loop buttons in the toolbar.
Set Loop
To repeat or loop a selected spline segment, select the keyframes to be looped. Select Set
Loop from the contextual menu or click on the Set Loop button in the toolbar. The selected
section of the spline repeats forward in time until the end of the global range, or until another
keyframe ends the repeating segment.

Changing and Removing the Loop
You can change the looped segment by modifying any of the keyframes or control points
originally used to create the loop. Simply select one of the originating key points, make any
necessary modifications, and the looped segment updates. To remove the loop, select the
keyframes you used to create the loop, and then click the Loop button in the toolbar.
Ping-Pong
The Ping-Pong Loop mode repeats the selected segment, reverses each successive loop, and
then repeats. Ping-pong looping can be enabled on the selected segments from the context
menu or the toolbar.
