Introduction to Geometric Dimensioning and Tolerancing Program

The GeoTol Pro Fundamentals course is a fully professional level course that provides knowledge on the basics as well as the more advanced concepts of geometric tolerancing. It is delivered per the ASME Y14.5-2009 dimensioning and tolerancing standard and consists of 17 interactive units.

This introduction to geometric dimensioning and tolerancing has been presented and refined over the past 30 years and covers what a person needs to know in order to work in an engineering, manufacturing and quality environment on a daily basis. The program is designed to build knowledge in steps, keeping the students engaged all the way through. This program is great for people new to the subject, those looking for a refresher course, or people who are interested in the more advanced and specialized concepts of geometric tolerancing.

The units start with a series of video clips of both Al Neumann and Scott Neumann teaching the lesson. Al and Scott trade-off, sportscaster style, teaching the subject by talking about the engineering drawings, showing computer animations and using wood and plastic models to demonstrate inspection techniques. In between the video clips, the students are asked interactive questions on the screen. The questions range from multiple choice, drag-and-drop, or hotspot buttons. After the questions, Al and Scott then provide the answers before continuing to the next topic. The student’s grades are tracked and reported at the end of each unit.

The students may follow along with the lessons in their GeoTol Pro fundamentals workbook (2009) with pages that match the slides on the screen. The 6-month access also allows the students to go back and review both the video clips and questions to reinforce the concepts as needed. See the program outline for the topics covered.
