In the Shape tab of the Inspector, choose Airbrush from the Brush Type pop-up menu.
Once the Brush Type is changed to Airbrush (or Image), the following occurs:
 The stroke softens because it is using a soft brush type. A paint stroke is comprised
of dabs and the brush type is the source for the dabs. The brush profile can be
modified to vary opacity within the brush. You can apply a custom opacity gradient
to the brush profile.
 The Stroke pane becomes available. Use the Stroke pane to set the Stroke Color
mode and Brush Scale parameters, and to adjust the Opacity, Spacing, Width, Angle,
and other options.
 The Advanced pane becomes available. The Advanced pane contains a single group
of controls that allow the dabs of a paint stroke to be animated like particles. For
more information on Dynamics, see “
Note: When a paint stroke is created using the Paint Stroke tool in the Toolbar,
additional stylus parameters appear in the Advanced pane.

Use the controls in the Style, Stroke, and Advanced panes of the Shape Inspector to
