In the world of industrial design, the gap between a fleeting idea and a tangible product is vast. It is a chasm bridged by skill, technique, and, most importantly, visualization. Few individuals have built as sturdy and influential a bridge as , an associate professor, author, and sketching virtuoso from the Delft University of Technology (TU Delft) in the Netherlands. While many designers create products, Eissen dedicates his life to the process of creation—specifically, the art of drawing.
Co-authored with Roselien Steur.
Koos Eissen is not a household name like Apple’s Jony Ive, but within the global design education community, he is a titan. He is best known as the co-author of the seminal textbook "Sketching: The Basics" and "Sketching: Drawing Techniques for Product Designers." These books, co-created with Roselien Steur, have become the unofficial bibles in design faculties from Eindhoven to Seoul. They demystified the intimidating world of perspective drawing, marker rendering, and shadow casting, turning chaotic creativity into structured visual communication. koos eissen
