The Proportional Divider is not just for architects...it's an invaluable tool for artists! It's about transferring scale...align your desired subject matter in the small end of the divider and transfer the spacing of the larger end to your drawing surface. This simple drawing tool can teach you how to draw. Let's face it, the Fine Artist does not need the exacting precision that an architect might. We need to approximate proportions and landmarks, and The Accurasee Proportional Divider does just that at a fraction of the $100-$300 price tag of high end dividers. The divider is made of plastic and guaranteed for 1 year! The parts are sturdier than you might think. If anything happens or any part breaks, contact us...we'll happily replace it. If you're not satisfied for any reason, go ahead and return it! We'll refund cost + shipping.
