Instead of painting regular lines, add character to your mark marking with the shape tracking effects. In the Brush Tool settings window you will notice 6 tracking options to apply to your painted lines.

Each setting can be further adjusted using the Amplitude and Spacing settings, which increase and decrease the height and frequency of the shape being selected.

• Line - effectively switched the tracking off and lets the Brush Tool paint with no tracking effects applied
• Sine - from the word sinusoidal, meaning random and sinew like. This setting provides effects like the one shown below. We recommend you experiment with the amplitude and spacing settings to see what effects you can achieve.
• Square - gives a squared appearance to the edge of the shape
• Triangle - gives a triangular appearance to the edge of the selection
• Spring - creates a spring-like affect selection
• Random - creates a random shaped edge to your selection
