Dihedral Structure is a 14 X 17 pen and ink drawing, drawn using a .25 mm Rapidograph pen and black India ink. The initial design was created using a pencil, compass, ruler and protractor. Once the design is created, the final image is drawn over the pencil drawing freehand in ink. This drawing is available in 8×10, 11×14, and 16×20 archival quality prints. The 16×20 print has the same dimensions as the original drawing, just printed on slightly larger paper.
