James D. Bethune taught drafting and Computer Aided-Design (CAD) for 39 years, twice winning the Outstanding Professor of the year award. He has a doctor's degree in education from Boston University and has written more than 28 books on drafting and CAD. While retired from full-time teaching, Jim continues to write textbooks on CAD. An avid golfer, Jim lives in East Greenwich, Rhode Island. David Byrnes recently retired from a 38-year career of design, drafting, and 3D modeling. He has written and co-authored several books on AutoCAD. He was a contributing editor to Cadalyst Magazine (1990-2005), as well as the Canadian magazines CAD Systems and AutoCAD User. He taught 2D and 3D design software at Emily Carr University of Art + Design in Vancouver, British Columbia, for 15 years. He also taught at British Columbia Institute of Technology and the University of British Columbia during this time.
