I spent almost an hour trying to explain to an Engineer how GDnT works and how and why the part was failing. I would think with all of the GDnT on the prints they would have a better understanding of it. (I know its not all engineers may be just a few that I work with)
The newer engineers get 40 hours of instruction and are suddenly experts. So new or old the majority of engineers don't have a firm grasp and understanding of GD&T. There is the occasional exception, but the vast majority know just enough to be extremely dangerous.
After 25 years of programming CMMs staring at prints and working with GD&T, I've finally been asked to participate in APQPs and to give my thoughts on the prints.
