I'm a bit embarrassed to ask, but figured this would be the place to do it safely - everyone is always helpful here. In all my years of drafting, design, engineering and production management, I've never had the opportunity to create a casting drawing. (See my other project thread for how this opportunity came to be) Drafting Standards: this was the best I could find. What I'd like to know is the convention for calling out a feature dimension that has draft. For example, if there was a boss on a face, do I call out the diameter at the base or the diameter at the top? The pattern maker would know to add draft, but what is the industry convention - or is their one? So here is a screenshot of one of the many gear hobber castings...These aren't meant to represent patterns, but rather "as cast". My intent is that somebody who cared to recreate these could at least work backward into their wood patterns from here.

Hopefully you can see the dilemma: in the right side view do I call out the 1" width at the bottom of the dovetail way, or do I call it out at the top? In the top view, do I call out the 1-3/8" at the top of the ways, or do I call it out from the bottom? The bottom has fillets...how does one consider the dimensions of these types of features with draft and fillets? In short, what is the preferred method of calling out features with draft?
