Easy Plotting / Multi-functional Ruler

Easy Plotting
Easy Plotting

The multi-functional ruler is composed of one ruler, one shaft and one slider. It can be often used in four ways: drawing continuous straight lines, drawing intersecting lines, drawing parallel lines, drawing circles. The ruler is used to draw lines. The shaft can locate points, control the rotation angle, and be a magnifying glass with its convex shape. The slider can maintain the relative position and measure the distance. The multi-functional ruler will simplify each of the four ways into four steps and help you complete geometric construction work easily, instead of former drawing tools.
