Convert control points between corners and curves
Do one of the following:
m Command-click a curved point to turn it into a corner (Linear) point.
m Command-drag a corner point to turn it into a curved (Bezier) point, creating adjustable
tangent handles.
m Control-click selected points, then choose Linear, Smooth, or Very Smooth (for B-Splines) from
the shortcut menu to change the control point type.
Adjust a Bezier curve using the control point’s tangent handles
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 various 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.
Do one of the following:
m Drag a tangent handle to adjust its length. By default, the opposing tangent is locked to 180
degrees, and adjusting the angle of one tangent adjusts the other. However, the length of each
tangent can be independently adjusted.
m Option-drag either tangent to break the relationship between opposing tangents. After this
relationship is broken, adjustments to one tangent have no effect on the other, and both
tangents can be rotated freely.
