Controlling Curves with Control Points
To define the curve associated with an anchor point, follow these steps:
- Select the Convert Anchor Point tool on the Pen tool flyout.
- Click the desired anchor with the Convert Anchor Point tool.
- Drag the anchor in the direction that you want the curve to go. Notice that the anchor itself doesn’t move. Instead, control points appear.
- Click-and-drag a control point away from the anchor to create a curve. Moving control points changes the direction of the anchor curve (see Figure 4). Experiment with rotating the control point to control the curve.
- Stretching out the control point handles (the lines that connect the control point to the anchor) increases the intensity of curvature.

Now that you know how to manipulate anchor control points with the Convert Anchor Point tool, you can combine the process of defining an anchor and manipulating control points. Click to define an anchor with the Pen tool, and then drag to define the control points (see Figure 5).
