Depending on the camera view, the object on the path may no longer be visible. For
example, if the object has not been rotated in X or Y space and you are working in Top
view, the camera is looking down perpendicularly (on the Y axis) on the object. The
motion path and its points are still visible (as long as the Motion Path behavior is
selected).
3 Drag a control point up or down to adjust the object in Z space.
Note: The motion path onscreen controls are available for all camera views.
To enter specific values for the control point locations, click the Control Points
disclosure triangle in the Motion Path behavior parameters. The first value field is X, the
second value field is Y, and the third value field is Z.
4 To reset the camera view, do one of the following:
Before the motion path is transformed in 3D
space, it appears flat when viewed from above.
The affected object only moves in X and Y
space.
Once the Z values are modified, the path is no
longer flat. The affected object moves in X, Y,
and Z space.
