Edit control points
Edit control points overview
Complex shapes, masks, and paint strokes are defined by Bezier splines and B-Splines, which
are built with control points. The control points, which lie along the spline in connect-the-dot
fashion, determine the shape and curvature of the spline. You can modify a spline by dragging
its control points and adjusting the tangent handles attached to each control point. You can
transform multiple control points simultaneously. You can add, delete, and lock control points.
And you can use dynamic guides and snapping to align control points to other control points
and other objects. This section covers various ways to edit control points.
Display control points
There are several ways to display the control points of a shape to allow point-by-point editing in
