Roughening objects

The roughening effect lets you apply a jagged or spiked edge to objects, including lines, curves, and text. You can control the size, angle, direction, and number of the indentations, whether you use a pen tablet or a mouse.

The roughening effect is determined by the movements of the stylus (or pressure-sensitive pen), by fixed settings, or by automatically applying perpendicular spikes to the line. Tilting the stylus toward and away from the tablet’s surface increases and decreases the size of the spikes. If you are using a mouse, you can specify a tilt angle between 0 and 90°. You can determine the direction of the spikes by changing the angle of rotation (or bearing) of the stylus as you apply the roughening effect to an object. When you are using a mouse, you can set the bearing angle from 0 to 359°. You can also increase or decrease the number of spikes that are applied as you drag.

The roughening effect also responds to the pressure of the stylus on the tablet. The more pressure you apply, the more spikes are created in the roughened area. If you are using a mouse, you can specify values to simulate the stylus pressure.

You can also change the brush nib size.

Roughening allows you to apply jags or spikes to part of an outline or path.

To roughen an object

1 .	Select a curve object using the Pick tool .

2 .	Click the Shape tools button in the toolbox, and click the Roughen brush tool .

You can also
Specify the size of the roughening spikes	Type a value between 0.01 and 2.0 in the Nib size box on the property bar.
Change the number of spikes in a roughened area	Type a value between 1 and 10 in the Frequency of spikes box on the property bar.
Change the number of spikes in a roughened area when using a pen tablet	Click the Pen pressure button on the property bar.
Specify the height of the roughening spikes	Type a value between 0 and 90 in the Tilt box on the property bar.
Increase the number of roughening spikes as you drag	Type a value between -10 and 10 in the Dryout box on the property bar.
Change the height of the roughening spikes when using a pen tablet	Click the Pen tilt button on the property bar.
Specify the direction of the roughening spikes	Choose Fixed direction from the Spike direction list box. Type a value between 0 and 359 in the Pen bearing box on the property bar.
Change the direction of the roughening spikes when using a pen tablet	Choose Stylus setting from the Spike direction list box on the property bar.
Create roughening spikes perpendicular to the path or outline	Choose Auto from the Spike direction list box on the property bar.

Objects with distortions, envelopes, and perspective applied to them are converted to curve objects before the roughening effect is applied.

To make the tilt angle and bearing responsive to the stylus, right-click the roughened object with the Roughen brush tool, and select a command from the context menu.

To see the minimum and maximum values for the roughening controls, right-click the control on the property bar, and click Settings.
