The shape changes to adjust to the missing point. If you remove points from a closed shape, the
shape remains closed.
After deleting point Before deleting point
WARNING: If you delete a point from a shape that has a keyframed shape animation parameter
in the Keyframe Editor, that control point is removed from the entire animation.
Lock control points
You can lock control points in a shape to fix them in place and prevent accidental modification. A
shape with locked points can still be moved.
Lock and unlock points
1 Choose the Edit Points tool, then select a shape.
2 Control-click a control point, then choose Lock Point from the shortcut menu.
If the point was unlocked, it becomes locked. If the point was locked, Unlock Point appears in the
shortcut menu, and the point becomes unlocked.
Locked points appear gray with
a black dot in the middle of the point.
Edit Bezier 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 converted from a hard corner to a curve.
Note: For all procedures described below, use the Edit Points tool (in the 2D transform tools
pop-up menu).
