(Child option) or for the entire hierarchy (Parent option). The Key Entire Hierarchy sets keys for the object
and its parents (Child option) or for the object and its targets and their hierarchies (Parent option).
This constraint also includes the PRS Parameters and Key Info rollouts.

You can use the Position constraint to control the position of an object in relation to its targets.

You cannot use Link constraints with Inverse Kinematics systems. n

Tutorial: Skating a figure eight
For an animated object to switch its link from one parent to another halfway through an animation, you
need to use the Link constraint. Rotating an object about a static point is easy enough: Simply link the
object to a dummy object, and rotate the dummy object. The figure-eight motion is more complex, but you
can do it with the Link constraint.
To move an object in a figure eight, follow these steps:
1. Open the Figure skater skating a figure eight.max file from the Chap 22 directory on the DVD.
This file includes a figure skater model imported from Poser and two dummy objects. The figure
skater is linked to the first dummy object.
2. Click the Auto Key button (or press the N key), drag the Time Slider to frame 100, and rotate the
first dummy object two full revolutions in the Top viewport.
