The left most view's quote is pretty bad. For round parts you should dimension either in diameter or in radius. Also , I cant figure out the taper from the dimension you put, there is no angl

What is a datum?
Honest question, I probably use a different term for it.
And absolutely I assume they'll have questions. I have things like the taper for ease of casting, which the dimen
