The direction line angle and length determine the direction and curvature of the curve. You can use the Ctrl switch selection tool to adjust the anchor points, and the error points can be deleted by Delete; 2. The tool provides three modes: the shape mode is used to draw vector graphics. The path mode is suitable for creating selections or strokes. The fill pixel mode is rarely used; 3.
