 The center, or axis, of rotation (for example, to rotate the object around its center
point, or around its top left corner). The center of rotation can be inside or outside the
object. If the center is outside the object, the object moves in an arc.
The following illustrations show how the rotation range and the center of rotation work.
Text objects always remain in their original orientation while rotating about their axis.
With the center of rotation at the center of the object, text objects do not rotate at all unless
part of a group of objects, to which you have applied rotation animation. To prevent a text
object from rotating, exclude it from the group of objects you are animating.
Changing the width of an object
Use width animation to change an object’s width, based on a tag value or the result of an
expression or a tag value, in relation to the specified minimum and maximum values.
The object’s width is proportional to the value of the expression. For example, if the value
of the expression is halfway between its minimum and maximum values, the object will
be half its full width.
For details about Width options in the Animation dialog box, click Help.

The object stops rotating
when tag values fall
within this range.
The object rotates when
tag values fall within this
range.
Tag values
With the center of rotation
inside the object, at the
top-left corner, this object
rotates from zero to 180
degrees as its tag value
changes.
