To reshape a line or shape outline, drag any point on a line using the Selection tool. The pointer changes to indicate what type of reshaping it can perform on the line or fill.
Animate adjusts the curve of the line segment to accommodate the new position of the moved point. If the repositioned point is an end point the line will lengthen or shorten. If the repositioned point is a corner, the line segments forming the corner remain straight as they become longer or shorter.

Some brush stroke areas are easier to reshape if you view them as outlines.
If you are having trouble reshaping a complex line, smooth it to remove some of its details, making reshaping easier. Increasing the magnification can also make reshaping easier and more accurate.
Straightening makes small straightening adjustments to lines and curves you already drew. It has no effect on segments that are already straight.

To adjust the degree of automatic smoothing and straightening, specify preferences for drawing settings.
To make Animate 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.
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 stroke, select the Selection tool and click the Smooth modifier
in the Options section of the Tools panel. Each click of the Smooth modifier button makes the selected stroke progressively smoother.
To enter specific parameters for a smoothing operation, choose Modify > Shape > Smooth. In the Smooth dialog box, enter values for the Smooth Angles Above, Smooth Angles Below, and Smoothing Strength parameters.
To make small straightening adjustments on each selected fill outline or curved line, select the Selection tool
and click the Straighten modifier
in the Options section of the Tools panel.
To enter specific parameters for a straightening operation, choose Modify > Shape > Straighten. In the Straighten dialog box, enter a value for the Straighten Strength parameter.
To use shape recognition, select the Selection tool
and click the Straighten modifier
, or select Modify > Shape > Straighten.
Optimizing smooths curves by refining curved lines and filling outlines, reducing the number of curves used to define these elements. Optimizing curves also reduces the size of the Flash Professional document (FLA file) and the exported Animate application (SWF file). Apply optimization to the same elements multiple times.

To convert lines to fills, select a line or multiple lines and select Modify > Shape > Convert Lines To Fills. Selected lines are converted to filled shapes, which allows you to fill lines with gradients or to erase a portion of a line. Converting lines to fills can make file sizes larger, but it can also speed up drawing for some animations.

To soften the edges of an object, select a filled shape, and select Modify > Shape > Soften Fill Edges. Set the following options:

Select Eraser tool and select the icon from the tool bar to enable pressure sensitivity or select the
icon to enable tilt sensitivity. The default percentage values are 1% and 100% corresponding to the minimum and maximum values of Pressure/Tilt.
Use the eraser tool to create variable-width strokes based on pressure or tilt applied on the Eraser.
A sample drawing drawn with the help of Eraser Pressure and Tilt options is shown below for illustration:
