This Advanced Geometric Dimensioning & Tolerancing (GD&T) workshop is for those with some previous exposure to geometric dimensioning and tolerancing. In this two-part workshop, Part 1 will be a review of the GD&T symbols and rules. In Part 2 more advanced topics are covered, including an update about the revised Y14.5-2018 standard.  We’ll also discuss the proper application of tolerances for designers, including a short module using a tolerance stack spreadsheet.
