As a HS Freshman, I took my first mechanical drafting class and my teacher said I was a natural. He encouraged me to pursue this line of work and I did. Got my first job as a Sophomore in a die design shop doing work on major automotive panels; fenders, quarter panels, hoods, deck lids... you get the point.
Back then, everything was manual drafting and my drafting equipment was a wall board section that was 8' tall and 30' long. Quite a leap from a high school drafting table but I was hooked and they were paying me 3 times what my buddies were making in their after school jobs and they were teaching me a trade called die design.
Here I sit at General Motors at 48, doing essentially what I did when I was 16, having spent a full two thirds of my life in this trade. It's safe to say that after 27 years at GM, if you've owned a GM vehicle, chances are that I've had a hand in it.
Getting back to the drafting tool discussion...
I put mine away about 23-24 years ago and it's been all Calma, CGS, Unigraphics NX and AutoForm. Calma and CGS have been retired for years now and I use NX and AF everyday on my HP engineering workstation. No regrets, it's been a good living and I'm grateful to GM for "lifelong" employment.
