The descendents shift position because of the

After a hierarchy is created, you can scale the position of the
children without changing the individual objects’ dimensions.
Rotating the hierarchy does not affect the individual objects’
orientation.
Al igning Pi vots
Buttons on the Alignment group b ox of t he Adjust
Pivot rollout change names based on the state
of Affect Object Only and Affect Pivot Only.
Alignment is disabled when Affect Hierarchy Only
is active.
Center to Object/Pivot—Moves the object, or pivot,
so the pivot is at the center of the object.
Align to Object/Pi vot—Rotates the object, or pivot,
to align the pivot with the object’s original local
coordinate system.
Align to World—Rotatestheobject,orpivot,to
align with the world coordinate system.
Resetting the Pivot

V iewing and Selecting Hierarchies
There are a number of ways to view a hierarchy
structure and select objects i n it.
Viewing a Hierarchy
You can use these methods to view the relationships
between parents and children in a linked hierarchy.
•TheSelect Objects dialog (page 1–78) appears
whenever you use a by-name selec tion method,
such as choosing Edit menu > Select By > Name,
by clicking Select By Name on the main toolbar,
or by pressing the
H key .
To list objects hierarchically, turn on Display
Subtree on the dialog. This indents children
below their parent.
•TheHierarchy list (page 2–512) attheleftsideof
the Track View window (page 2–501) displays a l l
objects using indentation to express hierarchy.
Child objects are displayed indented and below
their parent. An added advantage of Track View
