Bring our best-selling GD&T DVD course to your company or classroom for unlimited viewing. Our presentation has become the industry standard for teaching GD&T and has been continually refined and perfected for over 35 years. This comprehensive video series is designed to cover everything personnel need to know in order to function and work in an organization that uses geometric tolerancing. This video series progresses from basic concepts all the way into advanced applications.

Designed for self-learning or for use in a classroom type setting within a school or company. Ideal for teaching a uniform interpretation and application of GD&T to all personnel; including engineers, designers, inspectors, machinists and shop floor personnel. This is an invaluable tool for any quality improvement strategy.

The GD&T DVD series consists of 17 units, each approximately 1 hour in length with about 1 hour of student exercises. The video presents GD&T concepts in an easy to understand, sports-caster type presentation. The internationally recognized GD&T experts, Scott and Al Neumann, use 3D models to simulate the graphics, concepts and inspection techniques for an exciting hands-on feel. The students follow along with the page numbers in the video and perform exercises to test their knowledge along the way in the recommended (not included) GeoTol Pro 2009 Workbook.

Awards: The GeoTol Pro 2009 Video Series earned a Platinum Award from the 2009 Ava Awards competition. The Ava Awards recognize outstanding achievement by creative professionals involved in the concept, writing, direction, shooting and editing of audio-visual materials and programs. There were more than 1,700 entries from throughout the United States, Canada and several other countries in the 2009 competition, which is sponsored and judged by the Association of Marketing and Communication Professionals. Only 210 entries received the highest platinum award level.
