Draw free-form paths by plotting points with the Pen tool

Plotting points is like drawing a connect-the-dots picture. When you click each point with the Pen tool, Fireworks automatically draws the path of the vector object from the last point you clicked.

In addition to connecting the points with straight segments, the Pen tool can draw smooth, mathematically derived curve segments known as Bezier curves. Each point's type—corner point or curve point—determines whether the adjacent curves are straight lines or curves.

You can modify straight and curved path segments by dragging their points. You can further modify curved path segments by dragging their point handles. You can also convert straight path segments to curved (and vice versa) by converting their points.
