The Inherit rollout for objects using standard position, rotation, and scale
controllers contains three groups: one each for Move, Rotate, and Scale. Each
group contains three options, one each for the X, Y, and Z world axes.
■ When turned on, transform information from the parent is passed on to
the child for the selected World axes.
■ When turned off, transform information for the selected axes is ignored
by the child.
Imagine you are animating a Ferris wheel that rotates on the world Y axis.
The wheel is the parent and the cars are its children. You want the cars to
ignore the Y axis rotation of the wheel. Otherwise, the passengers would all
fall out. You use Link Info to turn off the Y axis option on the Rotation group
of the Inherit rollout for each car.
Using the Link Inheritance Utility
The
Link Inheritance on page 3372 utility works exactly the same as the Inherit
rollout in the Link Info group on the Hierarchy panel, except that you can
set link inheritance for multiple objects in a selection set.
For example, on a Ferris wheel, you could select all of the cars and use the
Link Inheritance utility to turn off Y axis rotation for all the cars at once.
Link Inheritance (Selected) Utility
Utilities panel > Utilities rollout > More button > Utilities dialog > Link
Inheritance (Selected)
The Link Inheritance (Selected) utility constrains the links between multiple
objects in a selection set for any axis of position, rotation, or scale.
This utility works exactly the same as the
Inherit rollout on page 3502 in the
Link Info group box in the
Hierarchy panel on page 7661, except that it lets you
adjust link inheritance for multiple objects in a selection set, while the
functions in the Hierarchy panel work only on single objects.
Procedures
To prevent the inheritance of X rotation in a hierarchy:
■ Select one or more objects, and then turn off X in the Rotate group of the
Inherit rollout.
