Auto Termination R ollout
(Inter a ctive IK)
Make a selection. > Hierarchy panel > IK button > Auto
Termination rollout
The Auto Termination controls temporarily assign
termina tors a specific number of links up the
hierarchical chain from the selected object. T his

with applied IK or with IK solvers.
Procedure
To use a uto ter mination:
1.
In the Auto Termination rollout, turn on Auto
Te r m i nat i on.
2. Enter a value in the # of Links Up field.
TurnontheIKbuttononthetoolbar.
3. Select any object in an IK chain to move or
rotate.
Inter face
Interactive IK Auto Termination—Turns on the auto
termin ation feature.
#ofLinksUp—Specifies how far up the chain the
termination is applied.
For example, if you set this to 5, when you move
any object in the hierarchy, the object that’s five
links up the chain from the object you’re adjusting
acts as a terminator. If you select a different
object in the hierarchy, termination is switched to
whichever object is five links up the chain from
the newly selected object.
A setting of 1 simply locks the hierarchy, since
it terminates the joint just beyond the currently
selected object.
Link Info
Make a selection. > Hierarchy panel > Link Info button
This part of the Hierarchy panel contains two
rollouts. The Locks rollout has controls to restrict
the m ovement of objects in a particular axis. The
Inherit rollout has controls to limit the transforms
that a child inherits from its parent object.
