Project title
An existing ruler can only draw a straight line. It is inconvenient to have a separate character in order to draw a circle, an ellipse, or a curve. In reality, we do not have a ruler. To solve this inconvenience, I came to think about this product. This Ruler is designed to draw straight lines or curves. You can also measure the length of the curve.
