I have this hole on the right that I use for a retaining pin. My vendor has started drilling them crooked. I would like to constrain it to be parallel with the axis through the vertical center line of the larger hole.

Is there a proper geometric tolerance to use for this? The parallel tolerance does not seem to cover this.

How is the angle captured then since there is no datum through the vertical axis used for the angular dimension?

You can't specify the vertical portion of a centerline as a datum.

The large hole in your part is the same as the 80.2/80.0 dimension [-B-]. The "into the page" dimension is to the [-A-] datum.

The small hole axis would have to remain within the diametrical tolerance for the entire distance which through the part which is how true position controls angularity.
