Modifying shapes with the Envelope modifier

The Envelope modifier lets you warp and distort objects. An envelope is a bounding box that contains one or more objects. Changes made to an envelope's shape affect the shape of the objects contained within the envelope. You edit the shape of an envelope by adjusting its points and tangent handles. See Adjusting segments.

To modify a shape with the Envelope modifier:

Select a shape on the Stage.
Note: The Envelope modifier cannot modify symbols, bitmaps, video objects, sounds, gradients, object groups, or text. If a multiple selection contains any of these, only the shape objects are distorted. To modify text, first convert the characters to shape objects.
Select Modify > Transform > Envelope.
Drag the points and tangent handles to modify the envelope.
