Interpreting Engineering Drawings

Ted Branoff has been involved in engineering graphics education at North Carolina State University since 1986. Prior to that he worked with Measurements Group creating printed circuit board layouts and with Siemens Energy and Automation creating mechanical specifications for switchgear. He has taught courses in introductory engineering graphics, computer-aided design, descriptive geometry, geometric dimensioning and tolerancing, and instructional design. In addition he has conducted CAD and geometric dimensioning and tolerancing workshops for both high school teachers and local industry. He is currently the undergraduate program coordinator for the Technology, Engineering & Design Education Program, which prepares teachers for middle schools and high schools. He is also the current president of the International Society for Geometry and Graphics (2009-2012).
