Tweening
Choose Insert > Tween Instances to blend a symbol and
one or more of its instances, creating interim instance
objects with transitional attributes. This is known as
tweening. Alternatively, tween two or more instances
without using a symbol.
Instance objects created by tweening derive attributes
from the symbol or instance objects used. For
example, tween a vertical symbol with a horizontal
instance to produce instance objects that rotate
progressively to form a blend from the vertical object to
the horizontal object.
Tweening can apply to these object characteristics:
Transformations—
Tween between objects with
different rotation, scaling, or skew transformations.
Opacity—
Tween between opacity settings of the same
opacity type.
Live Effects—
Tween between settings of the same Live
Effects.
To tween:
1
Select objects to be tweened.
Select a symbol and one or more of its instances
or select two or more instances of the same
symbol object.
2
Choose Insert > Tween Instances.
3
Enter the number of tween steps in the Tween
Instances dialog box and click OK.
Check Distribute to frames to distribute the
tweened objects to separate animation frames.
