Enable The Pen Tool’s Rubber Band

When using the pen tool, it may be hard to see how the next curve will appear.

To enable the Rubber Band, which shows you an interactive preview of your next curve (much like Illustrator), go to the Options Bar. Then under the “Geometry options” (gear icon) drop-down check the Rubber Band check box.

You will now see an interactive preview of your next curve before you add it.
