To Construct a Line

To Construct a Line:

1. Choose the Line tool if it’s not already active.

2. Click to locate a first point through which the line travels. (You can click in empty space, on an existing point, on a path object such as a segment or circle, or on an intersection.)

3. Click again to locate a second point through which the line travels.

If you prefer, you can use any of the Straightedge tools by pressing the mouse button at the location of the first point, dragging the mouse, then releasing the mouse button at the location of the second point.
