Using
the Pen tool, drag to create the first smooth point of a curved
segment.
Reposition the Pen tool and drag to create a curve with
a second smooth point; then press and hold Alt (Windows) or Option
(Mac OS) and drag the direction line toward its opposing
end to set the slope of the next curve. Release the key and the
mouse button.
This process converts the smooth point to a corner point
by splitting the direction lines.
Reposition the Pen tool where you want the second curved
segment to end, and drag a new smooth point to complete the second
curved segment.
