Editing Bezier Curve Control Points
The methods used to adjust Bezier shapes are similar to those used by many other
applications. Bezier control points are widely used to modify curves, and allow you to
easily draw any shape you may need.
Each point in a Bezier shape can be toggled to act as a hard corner or as a curve.
To toggle control points between corners and curves, do one of the following:
m Command-click a curved point to turn it into a corner point.
m Command-drag a corner point to turn it into a curved point, creating adjustable
tangent handles.
m Control-click one or more selected points, then choose Linear or Smooth from the
shortcut menu to change the control point type.
Curved Bezier control points have two tangent handles that you use to adjust the
curvature of the shape on either side of the control point. These handles can be
adjusted in a variety of ways to create symmetrical and asymmetrical curves. By default,
these tangent handles are locked to one another at an angle of 180 degrees, although
this can be overridden to allow each tangent to be independently adjusted.
Important: If automatic keyframing is turned on, turning a corner into a curve results in
an animated effect of the corner gradually turning into the curve.
Locked points appear gray.
