Each print includes a text which gives details of the location within a square of a geometric figure. Each print concerns a different figure; circle, square, triangle, rectangle, parallelogram and trapezoid. Above each text is an image which is a visual equivalent to the text, portraying each figure and the points and lines that Lewitt used to plot it. The mark of the etching plate provides the outer frame for each figure. When Lewitt made this work the texts preceded the images, which were mapped out on paper before being etched onto the plate. Etching was chosen because it provided the fine lines he wanted. Lewitt compared his procedure to plotting navigational routes.
