TIP Use names that can help you to identify your scene components in
future.
Work with Animation Sets
An animation set contains a list of geometry objects to be animated, and a
list of keyframes that describe how it is to be animated.
Your scene can have as many animation sets as you want, and you can also
have the same geometry objects in different animation sets within the same
scene. The order of animation sets within a scene is important, and can be
used to control the final object position when the same object is used in
multiple animation sets.
Add Animation Sets
An animation set can be based on the current selection in the Scene View,
or on the current selection set or current search set.
When you add an animation set based on a selection set, the contents of the
animation set is automatically updated if the contents of the source selection
set change.
When you add an animation set based on a search set, the contents of the
animation set is updated each time the model changes to include everything
in the search set.
NOTE Any changes to search/selection sets during the animation playback are
ignored.
If the model changes so that objects in a particular animation are missing,
they are automatically removed from the animation set when the
corresponding NWD or NWF file is resaved.
Finally, if the selection or search sets are deleted rather than being lost, the
corresponding animation set becomes a static selection of objects based on
what it last contained.
