Richard Marklin is a professor in the Department of Mechanical Engineering at Marquette University. Since 1991 he has sustained a physical ergonomics research program at Marquette University. In 2007 he developed a methodology to teach people how to visually communicate their ideas for products and systems with freehand sketches. Freehand sketching requires only a pencil and blank paper (no gridlines). No instruments such as rulers, triangles, etc. are used, and no visual art talent is required. Although anybody can learn how to freehand sketch with his method, he validated the technique with 150 engineering students in the U.S., Costa Rica and the Netherlands. He created a YouTube channel (Marklin Freehand Sketcher) that has 10 videos that show how to sketch manufactured objects. He will use the methodology shown in the videos to teach CFK students how to freehand sketch objects.
