Motion paths in the animate state allow you to visualize the motion of controls as curves in 3D space and alter the curves in the viewport.

To display the motion path for a control:

  1. Select the control in the animate state.

  2. Bind the control to a motion path:

    The motion path for the control is displayed, and the keys on the control are displayed as dots on the motion path. These dots are the motion path controls.

    To display the entire motion path, turn off Visible Frames. You can also control the visibility of the motion path using selection sets - the motion path is found in All Controls ▸ motionpath.

    Note

    A motion path can only be displayed for one control at a time.

  3. Move the motion path around by selecting the motion path controls and adjusting the handle:
