Hello Sir, I have watched all your videos & they are brilliant. It helped me understand the basics of GD&T. Can do you a video on (hole to hole) and (hole to slot) datum strategy? I work for a sheet metal company & they tend to use this a lot.

Hallo Palani, I have a question: I have seen in some drawings that the datum A is composed of 5 points in diferent heights, so as you know, only 3 points are necessary and always the 3 "highest" will at the end be the "plane" where a solid part will rest (not flimsy), so what about the virtual condition of the plane formed with more than 3 points, should that be calculated like a sort of "average"? or the maximum limits are the ones to be taken? (question for measuring in CMM purposes)

Thanks for your Videos!
