Versatile and easy to use, this precision tool allows you to draw circles, straight lines, and complex geometric shapes with accuracy and artistry. Construct, copy, and read angles; measure and convert inches and centimeters; and much more. To use this device, simply slide the cursor to the desired position and lock; placing a finger on the transparent swivel disk will anchor the ruler as you draw with the pencil point in the cursor hole.
