Yeah I was trying to do it quick just to show the mixed coordinate types and the fact that the axis is based off the small hole and big hole alignment but dimensioned off the larger. Here's perhaps a better defined quick mock up.
We're working on the dimensioning convention of this drawing and one of my engineers gave me something like this, it makes sense to me but I'm not sure if it's technically "legal" anyone have any input? the important mating features are the two holes, but it's easier to dimension from a vertical...
