Draw curved manual Bezier path segments with the Pen tool
You create a curved path segment by dragging direction lines. The length and direction of the direction lines
determine the shape of the curve.
Shift-drag to constrain the angle of the direction lines to whole multiples of 45˚. Alt-drag (Windows) or Option-drag
(Mac OS) to modify only the outgoing direction line.
1 Place the Pen tool where you want the curve to begin, and hold the mouse button down.
A vertex appears, and the Pen tool pointer changes to an arrowhead.
2 Drag to modify the length and direction of both direction lines for a vertex, and then release the mouse button.
