How to Edit Shapes
There are two ways to edit shapes. You can edit them in their entirety, like any other
object, using the Transform tools, or you can adjust them point by point using the Adjust
Control Points tool. The shape-editing techniques in this section apply to both shapes
and masks.
You perform most of your detailed editing using a shape’s individual control points. The
Transform and Shear tools are better for overall transformations of an entire shape. The
following guidelines apply to all shape types: shapes, masks, and paint strokes.
Using Dynamic Guides and Snapping While Editing
The Canvas Dynamic Guides and control point snapping help you snap the selected
points to one another. You can snap the points of one shape to other points on that
shape, or you can snap the points of one shape to the points of a different shape.
To use control point snapping on a single shape
1 In the View menu above the right side of the Canvas, ensure that Dynamic Guides are
turned on.
2 Choose View > Snap to ensure snapping is turned on.
When active, a check mark appears next to the menu item.
3 Select the shape you want to edit, click the Select/Transform tool, and while holding
down the mouse button, choose the Adjust Control Points tool from the pop-up menu.
Note: In the Canvas, you can also Control-click a shape and choose Edit Points from the
shortcut menu.
4 In the Canvas, drag a control point.
Guides appear when the selected control point aligns with other control points on the
shape.
