Draw straight segments with Pen Tool

Draw straight lines by clicking Pen Tool in the drawing area. This creates object anchor points, that are connected by straight segments.

Select Pen Tool.
Position the tip of the pen point where you want the straight segment to begin, and click to define the first object anchor point. The object anchor point remains selected (solid) until you add the next point.
Note: The first segment you draw is not visible until you click a second object anchor point. Also, if lines extend from either side of the point, you’ve accidentally dragged Pen Tool; choose Edit > Undo and click again.
Click again where you want the segment to end. (Shift‑click to constrain the segment’s angle to multiples of 45°.) This creates another object anchor point.
Continue clicking Pen Tool to create additional straight segments. The last object anchor point you add appears as a large square, indicating that it is selected.
Complete the path by doing one of the following:
- To close a path, click the initial object anchor point. A circle appears underneath the pen pointer when it is directly over the initial object anchor point.
- To leave the path open, Ctrl-click (Windows) or Command-click (Mac OS) anywhere away from all objects, or select a different tool in the Tools panel.
