Straighten and smooth lines
To reshape lines and shape outlines, straighten or smooth them.
Straightening makes small straightening adjustments to lines and curves you already drew. It has no effect on segments that are already straight.
To make Flash recognize shapes, use the straightening technique. If you draw any oval, rectangular, or triangular shapes with the Recognize Shapes option turned off, use the Straightening option to make the shapes geometrically perfect. Shapes that are touching, and thus connected to other elements, are not recognized.
Smoothing softens curves and reduces bumps or other variations in a curve’s overall direction. It also reduces the number of segments in a curve. Smoothing is relative, however, and has no effect on straight segments. It is particularly useful when you are having trouble reshaping a number of very short curved line segments. Selecting all the segments and smoothing them reduces the number of segments, producing a gentler curve that is easier to reshape.
