MARK DIX began working with AutoCAD in 1985 as a programmer for CAD Support Associates Inc. He helped design a system for creating estimates and bills of material directly from AutoCAD drawing databases for use in the automated conveyor industry. This system became the basis for systems still widely in use today. In 1986, he began collaborating with Paul Riley to create AutoCAD training materials, combining Riley's background in industrial design and training with Dix's background in writing, curriculum development, and programming. Dix and Riley have created tutorial teaching methods for every AutoCAD release since version 2.5. Dix has a Master of Arts in Teaching from Cornell University and a Masters in Education from the University of Massachusetts.
PAUL RILEY has been an Instructor and designer specializing in graphics and design of multimedia. He is a founding partner of CAD Support Associates, a contract service and professional training organization for computer aided design. His 15 years of business experience and 20 years of teaching experience are supported by degrees in education and computer science. Paul has taught AutoCAD at the University of Massachusetts, Lowell and Mt. Ida College in Newton, MA. He has developed a program, Computer Aided Design for Professionals, that is highly regarded and has been an ongoing success for the past 15 years.
