Yo Brad Bitenc!
It’s no problem you contacting me at all. I’m big on knowledge. Asking questions is the only way to get it & asking a stranger is no less.
A Draftsman could be a position in many types of fields and there is actually a HUGE market for them in the world actually. The architect create the pretty buildings designs and the Draftsman actually does the dirty work to make it work. A Draftsman has rules, an architect doesn’t. That’s my experience. I worked as a 2D Draftsman, drawing BLUEPRINTS for items to be fabricated out of steel using AutoCADD (which is the industry standard in most cases - at least in the US). I’m experienced in drawing layouts for beams to construct buildings, from laying out every single bolt location and hole size, to being responsible for elevations. I also construct drawings for simple items such as fences and gates. Yes, you do need to know building regulations and codes, but that and learning the trade comes hand in hand. This is just one application and one type of Draftsman. You can also be a 3D draftsman creating designs for fabrication for items from moving parts for a watch—to a Stealth Fighter. I hope this answer your questions and thoughts on being a technical draftsman. If you have any more, you’re more than welcome to ask more!
