Chapter 12 Using Shapes and Masks 833
To adjust a Bezier curve using the control point’s tangent handles, do one of
the following:
m Drag a tangent handle to adjust its length. By default, the angle of each opposing
tangent is locked to 180 degrees, and adjusting the angle of one tangent automatically
adjusts the other. The length of each tangent can be independently adjusted.
m Command-drag either tangent to break the relationship between opposing tangents.
Once this relationship is broken, adjustments to one tangent have no effect on the
other, and both tangents can be rotated freely.
m Command-drag a free tangent to reconnect its 180-degree relationship to its opposing
tangent. This locks both tangents together again.
Tip: Press Shift while you adjust a tangent to constrain its movement to 45-degree
angles.
To simultaneously modify the handles for more than one control point, Shift-select the
points and then adjust the tangents.
