When you want to draw a perfect circle with compass drawing tool, we need the help from ruler as well. Min Keun Kwon, a Korean industrial designer, wants to design a better tool that allows us to draw a measured circle without a ruler. Ruler Compass is a conceptual tool that you can use to draw any size of circle without manually measuring the size with a rule every single time.
Move one of Ruler compass’ legs, the gradation will revolve to show the radius. The gear connected with the leg will inform you about the radius by moving the center axis.
