Stop it guys my head is swelling
The only work I've done on the board is minor amendments (revisions) although this was on virtually every media including linen!
I'm very much from the CAD generation, in fact 3D CAD not even 2D. However I have had relatively little formal training and when starting in work didn't know about things like detail views etc.
I learnt it pretty much all on the job mostly from experienced drafters/checkers who had started on the board and a bit from reading the standards etc. Probably the most useful thing that's helped me learn is the drawings checking process but as we all know this isn't what it once was in most places.
At least the OP asked the question which shows he cares, which is more than can be said for a lot of people creating drawings these days, although maybe some of them don’t know they don’t know, if you catch my drift.
Anyway to the OP, sorry this has got off topic, Chris probably gave the answer you need days ago. Try and get copies of the most relevant ASME Y14.100 series standards if you can (I assume you’re US) as these are the final word on most of these types of questions however, if you have more questions don’t hesitate to post, we’ll try and keep it on topic next time!
KENAT, probably the least qualified checker you'll ever meet...
