Perspective Ruler

Perspective Ruler comprises two fixing discs connected by an extendable string. The two discs can be fixed in place via suction, and the drawing tool placed against the string. As the brush moves, the line stretches to point out the drafting path according to the principle of drawing perspectives. Following the path allows a perspective drawings to be made accurately. This approach is convenient for both designers and engineers who need to draw perspectives for work, as well as non-professionals and beginners who haven’t been trained in perspective drawing. With this tool, time can be saved and the principle of perspective drawing can be easily picked up, making the experience of drawing three-dimensional spaces more intuitive and fun.
