Dash away all in Flash

The new dash adjustment option for strokes will make dashes look as if they were carefully and correctly placed and evenly distributed on a path and cleanly bisecting any corners, even on complex shapes such as a 20-pointed star. To turn this option on, go to the Stroke panel (Window>Stroke), click the Dashed Line checkbox, and select the second icon to the far right: Aligns Dashes to Corners and Path Ends, Adjusting Lengths to Fit. Want to keep that setting turned on for future object creation? Deselect New Art Has Basic Appearance from the Appearance panel's flyout menu (Window>Appearance).
