About the Contour Editor Tool
The Contour Editor lets you reshape drawings. By displaying vector points around a shape and the central vector points in a pencil line, you can pull or push on these points to adjust the brush’s line thickness. Points can be selected and deleted. Each point has two Bezier handles for correcting the curves between two points. You can modify shapes by pulling and pushing directly on the segment between the points. You can use it to perfect a central shape pencil line, a contour shape brush line, or even create an elaborate shape from a basic ellipse or square.
