I graduated from a tech school in 1988 learning basic drafting and Autocad v10. Job-shop'ed for next decade or 2+ and did not stay in one field. I am old-school cad monkey that is getting back into the the industry and currently using: Product Design suite: Autocad Mech, +Inventor, +showcase v2013. I do wish I had a faster system. (HP Elitebook 8740w, i7-720, 16gig ram, Quadro FX 3800m).
Some college + Tech School.
