Adding anchor points can give you more control over a path or it can extend an open path. However, it’s a good idea not to add more points than necessary. A path with fewer points is easier to edit, display, and print. You can reduce the complexity of a path by deleting unnecessary points.
The toolbox contains three tools for adding or deleting
points: the Pen tool , the
Add Anchor Point tool
, and
the Delete Anchor Point tool
.
By default, the Pen tool changes to the Add Anchor Point tool as you position it over a selected path, or to the Delete Anchor Point tool as you position it over an anchor point. (In Photoshop, you must select Auto Add/Delete in the options bar to enable the Pen tool to automatically change to the Add Anchor Point or Delete Anchor Point tool.)
You can select and edit multiple paths simultaneously in Photoshop and InDesign; however, you can add or delete points to only one path at a time in Illustrator. In Photoshop and InDesign, you can reshape a path while adding anchor points by clicking and dragging as you add.
You can override automatic switching of the Pen tool to the Add Anchor Point tool or the Delete Anchor Point tool. This is useful when you want to start a new path on top of an existing path.
