Create Bézier Curves

Every line is composed of anchor points and line segments that connect those points.
Even a simple, straight line has two points, one at each end. More sophisticated shapes
can be created by adding anchor points and manipulating the direction handles of
those points to control the shape of segments that connect the different points. Note:
This concept is the heart of Bézier curves and vector-based drawing and can be
one of the most challenging skills for new designers to master. The Pen tool and its Bézier curves can be dif-

3. Click the second point on the line, press Shift, and drag right until the
ruler shows the cursor is at 5.625″.
When you click a point with the Convert Direction Point tool and immediately drag,
you add direction handles to the point. Those direction handles define the shape of
the line segments connected to the point. As you drag farther away from the point,
the affected segment’s curve increases.
Note:
Pressing Shift constrains the new direction handles to 45° angles — in this case,
exactly horizontal. If you look closely, you can see the direction handle on the left side Using the Convert
