Here's another example of halfway into the article, I could guess who wrote it. Hot Dawg - it's Norm stirring the pot again and making us think!
I was a drafter for 10+ years before being introduced to GD&T in 1990. That was more than 10 years of working alongside engineers who must also have not known or cared about GD&T, let alone stack-up analysis. (When I think of the countless hours of handlettering paragraphs of notes for runout, TIR, etc, and how GD&T symbols would have been so much simpler, I still roll my eyes & shake my head). It's a long in-grained culture that is resistant to change, but the hope is that people comfortable with 3D design will also champion 3D everything else, & they eventually will _become_ the culture.
