Draw shapes and paths with the Pen tool

Select the Pen tool (P) . 

Use the Options bar to customize tool settings, like Drawing Mode and Auto Add/Delete anchor points, to get the effect you want. 

Draw a path with anchor points and handles.

Finish drawing the path by closing it or leaving it open.

• Close the path: Position the tool over the first (hollow) anchor point and click or drag.
• Leave the path open: Ctrl-click (Windows) or Command-click (macOS) anywhere away from all objects.
