I have not. But from what I gather is the class is not about teaching GD&T but to teach how to use the Dimensioning part of the software. I see the benefit for such a class because it is more complicated now than back when it was only Legacy.
XactMeasure (the old feature control frame reporting method) is obsolete and was replaced with the Geometric Tolerance command in version 2020 R2.
Legacy still has it's uses but requires the user to interpret the print and to create the appropriate alignments and dimensions required to verify the specification. Legacy can not perform advanced datum fitting, is unable to report patterns of features and can not perform simultaneous evaluations. It is also, primarily designed to work with ASME. Although there is a registry setting (UseISOCalculations), the only real difference it makes is to use the single value method for profile (twice the largest deviation) instead of looking at the MAX and MIN.
Since their initial release, ISO and ASME have gradually diverged more and more, such that there are now considerable differences in both interpretation and function when working with ISO as opposed to ASME. One major difference is datum fitting - constrained MIN/MAX (ISO) vs Constrained L2 (ASME) and whether datums are fixed in location and orientation (ASME) or orientation only (ISO). All of this is covered in the new Hexagon GDT training course.
