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
the geometry of the object or its descendents.
The descendents shift position because of the
scaled or rotated links.

between lin ked objects and for adjusting bones to
match geometry.
After a hierarchy is created, you can scale the po sition
of the children without changing the individual objects’
dimensions.
Rotating the hierarchy does not affect the individual objects’
orientation.
