No, no specific program. Your local Tech school is good enough.
I'm looking to see if you have had formal training. After that, it is what you do with that knowledge that will make you a good or bad drafter. In other words, without your teacher looking over your shoulder, do you still do the right thing because you have pride in your work and because its the right thing? Or do you sloppily, do what you please because you want to be "artsy"?
A drafting/cad school will teach you those little "unwritten" rules. The way that you apply those rules will show up in your drawings.
From our perspective, we can teach you our specific work, but you must have good habits already.
Your enthusiasm will help a great deal. Keep that attitude!!
