Draw a free-form path
To draw a path that produces a pixel everywhere that your pointer touches, you use the Pencil tool. The result is a Path object whose points (or vertices) you can modify.
[!REMARQUE]
For a quick reference of modifications that you can make to a path, see Direct Selection tool modifier keys (Blend) and Pen tool modifier keys (Blend).
To draw a free-form path
In the Tools panel, click Pencil .
On the artboard, draw the free-form path just as you would using a real pencil.
