Re: roller plotter or parallel rulers?
For training and education purposes you should be able to use either tool, as long as you are comfortable. My preferred is the parallel rules because you can move in both directions across the chart as needed. Yes you can do it with the roller but you need a second parallel to change direction...and as stated above most chart tables are to small to use parallel rules. Good luck with your courses and always have your paper back up's
