The simplest path you can draw with the Pen
Tool is a straight line, made by clicking the Pen Tool to create
two anchor points. Continue to click to create a path made of straight
line segments connected by corner points.
Select the Pen Tool .
Position the Pen Tool where the straight segment is to
begin, and click to define the first anchor point. If direction
lines appear, you accidentally dragged the Pen Tool; choose Edit
> Undo and click again.
Note: The first segment you draw is not visible
until you click a second anchor point (unless you’ve specified Show
Pen Preview in the Drawing category of the Preferences dialog box).
Click again where you want the segment to end (Shift-click
to constrain the angle of the segment to a multiple of 45°).
Continue clicking to set anchor points for additional
straight segments.
Clicking pen tool creates straight segments
To complete the path as an open or closed shape, do one
of the following:
To complete an open path, double-click
the last point, click the Pen Tool in the Tools panel, or Control-click
(Windows) or Command-click (Macintosh) anywhere away from the path.
To close the path, position the Pen Tool over the
first (hollow) anchor point. A small circle appears next to the
Pen Tool pointer when
it is positioned correctly. Click or drag to close the path.
To complete the shape as is, select Edit >
Deselect All, or select a different tool in the Tools panel.
