Level 2 Online Course Details

The Level 2 program is the second part of a professional level course that takes the student past the basics of geometric tolerancing. It is delivered per the ASME Y14.5-2009 standard and consists of 9 interactive units. This program is great for people who have taken the Level 1 course and are ready for a more in depth study of the more specialized topics in 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 screen. The questions range from multiple choice, drag and drop, or hot spot 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 workbook with pages that match the slides on screen. The 12 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.
