You can reshape lines and shape outlines by straightening or smoothing them.
Note: Adjust the degree of automatic smoothing and straightening by choosing File > Assistant.
Use the Straighten modifier of the arrow tool or choose Modify > Curves > Straighten to make small straightening adjustments to lines and curves you have already drawn. Straightening has no effect on already straight segments.
You can also use the straightening technique to make Flash recognize shapes. Flash makes geometrically perfect any circles, ovals, rectangles, squares, triangles, and arcs you drew with shape recognition options turned off. Shapes that are touching, and thus connected to other elements, are not recognized.
Shape recognition turns the top shapes into the bottom shapes.
Smoothing softens curves and reduces bumps or other variations in a curve's overall direction. Smoothing also reduces the number of segments in a curve. Smoothing is relative, however, and has no effect on straight segments. Smoothing is particularly useful when you are having trouble reshaping a number of very short line segments. Selecting all the segments and smoothing them reduces the number of segments, producing a gentler curve that is easier to reshape.
Repeated application of smoothing or straightening makes each segment smoother or straighter, depending on how curved or straight each segment was originally.
To smooth the curve of each selected fill outline or curved line:
Select the arrow tool and click the Smooth modifier, or choose Modify > Curves > Smooth.
To make small straightening adjustments on each selected fill outline or curved line:
Select the arrow tool and click the Straighten modifier, or choose Modify > Curves > Straighten.
To use shape recognition:
Select the arrow tool and click the Straighten modifier, or choose Modify > Curves > Straighten.
