Description
Our GeoTol Pro 2020 Instructor PowerPoint has all the graphics from the accompanying GeoTol Pro 2020 Fundamentals Workbook. The slides are split into the same 14 units as the workbook and the leader may create a custom lesson plan by hiding slides or adding your own content. Instructor notes are included at the bottom of each slide as a guide. A lot of the graphics are animated to show tolerance zones and inspection methods. Save yourself hundreds of hours of slide prep with this ready-made package. GD&T basics training ppt comes in USB format.
