How do Engineers not understand GDnT?

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)

  • College Grads in mechanical engineering get two weeks of curriculum related to blueprint reading. They blow the dust off the top of the iceberg.
    They receive nothing regarding inspection methods or proper application of GD&T.

    Like Mike said above, most are extremely dangerous with that piece of paper, and no hands-on quality or manufacturing experience.
