Tip:
You can also link and un lin k hierarchies in
Schematic View (page 3–640).
Procedure

1.
Select the child object you want to unlink.
2. Click Unlink Selection.

representing its local center and local coordinate
system. The pivot point of an object is used for
a number of purposes:
• As the center for rotation and scaling when the
Pivot Point tr ansform center is selected.
• As the default location of a modifier center.
• As the transform offset for lin ked children.

YoucanadjustpivotpointsbyclickingPivoton
the Hierarchy panel, and then using features on
the Adjust Pivot rollout (page 2–488).
The functions under the Adjust Pivot rollout
cannot b e animated. Adjusting an object’s pivot
on any frame changes it for the entire animation.
Affecting Pivot Only
When Affect Pivot Only is on, move and rotate
transforms are only applied to the pivot of a
selected object.
• Movingorrotatingthepivotdoesnotaffectthe
object or its children.
• Scaling the pivot sca les the object from the
pivot center, but its children are unaffected.
Affect Pivot Only transforms t he pivot without moving the
object.
Affecting Object Only
When Affect Object Only is on, transforms are
appliedonlytoselectedobjects. Pivotsarenot
affected.
Moving, rotating, or scaling the object does not
affect the pivot or its children.
Affect Object O nly transforms the object without moving the
pivot.
Affecting Hierarchy Only

Scale transforms are applied only to the links
between objects and their children.
• Scaling or rotating an object affects the link
offsets of all its descendents without affecting
