• Identify any existing line. Enter, or indicate a point for the parallel construction line to pass through. Multiple parallel construction lines are drawn by entering or indicating further points for the lines to pass through.

• Enter the required separation of the line. Now identify any existing line. Finally, indicate on which side the parallel construction line should be drawn. Multiple lines can be drawn at the previously set separation by indicating the original lines and the desired sides.

• A set of parallel lines can be drawn from an original line. For example, if you enter line separations in the form: 10 20 30 40, four parallel lines will be drawn at the given distances from the indicated line.
