    There is a reason why draftsmen use a parallel bar, t-square, triangle or ruler to brace a mechanical pencil on. Having been a draftsman, I feel I can draw long lines faster and more accurately with a pencil and parallel bar than with a pencil with a pivoting wheel attached that has nothing from stopping the pencil from rotating while drawing.

    Just dont see how this will help draw straight lines. There is nothing to ensure the pencil moves in a straight line, the wheel just goes long with wherever you’re drawing!

    Hey Mr.Woo,
    Did you ever tried this, or modeled it in physical/reality? Can you please explain me how to draw a straight line with this device? I can tell you this should work on the virtual/designer desk only but sure not in reality. OTHER: Why some models has no display on it? I guess those are Bluetooth ones, and they inform the user through an earphone… whilst they are generating the required power/energy from the wheel spin.
