so it affects other object properties. It also alters the
properties passed hierarch ically from parent to child.
When you perform other operations on the object, such
as rotation, inverse kinem atics calculations, and other
positioning operations, you may not get the results
you expect. To recover from these problems, use the
Hierarchy panel’s Reset Scale button or the Utilities
panel’s Reset XForm utility. Either of these options
will reset the axes to use the no n-uniform scale as the
fundamental scale for the object.
As an alternative to non-uniform scaling with Select
And Squash, consider using the
XForm modifier (page
