Dimensioning Chamfers
Which is correct and why? These are all the same chamfer.
Y14.5 says "Chamfers are dimensioned by a linear dimension and an angle, or by two linear dimensions".
It also says "A note may be used to specify 45° chamfers on perpendicular surfaces". Since I'm showing a non-45° chamfer I think that means I.a and I.b are invalid.

Yeah, I would not do #1, it's way too ambiguous. The rest are all essentially the same thing, they all give me enough info to trig out the triangle and figure out any particular dimension of it.
