Draw curves with the Pen tool
Draw curved segments by dragging the anchor points with the Pen tool. When you use the Selection tool to select
an anchor point connecting curved segments, the segments display direction lines, which end in direction points. The
angle and length of the direction lines determine the shape and size of the curved segments. Moving the direction
lines reshapes the curves. A smooth point always has two direction lines that move together as a single, straight unit.
When you drag the direction point of either direction line on a smooth point, both direction lines move simultane-
ously, maintaining a continuous curve at that anchor point. In comparison, a corner point can have two, one, or no
direction lines, depending on whether it joins two, one, or no curved segments, respectively.
Corner point direction lines maintain the corner by working independently of one another. When you drag a
direction point on a corner point's direction line, the other direction line, if present, does not move. Direction lines
are always tangent to (perpendicular to the radius of) the curve at the anchor points. The angle of each direction line
determines the slope of the curve, and the length of each direction line determines the height, or depth, of the curve.
Select the Pen tool.

2 Position the cursor where you want the curve to begin. Hold down the mouse button.
Drag to create direction lines that determine the slope of the curve segment you're creating. In general, extend
3
the direction line about one third of the distance to the next anchor point you plan to draw. Shift-drag to constrain
the direction line to multiples of 45 °.
Release the mouse button.

Note: The first segment will not be visible until you draw the second anchor point.
5 Position the Pen tool where you want the curve segment to end.
•
To create a C-shaped curve, drag in a direction opposite to the direction that you dragged to create the previous
anchor point.

Drawing second point in curves
A. Starting to drag second smooth point B. Dragging away from previous direction line, creating C-shaped curve C. Result after releasing
mouse button
• To create an S-shaped curve, drag in the same direction that you dragged to create the previous anchor point.

Drawing S curves
