I know, it sounds weird, but I have a print that calls for Parallelism of the Center line of the part to 2 Datums, both of which are perpendicular Cylinders on the right side of the part. What would be the best way in dimensioning it?
I'd say that is a wrong callout. Can you get clarification from the designer? If the designer can explain what their intent is, maybe you can advice on a GD&T tolerance that fits the purpose better.
I mean, what should this centerline through the 5 cylinders be constructed from? The top or bottom of each cylinder or their centerpoints?
I really think what they are trying to achieve is parallel to the face on that side (which it passes for), but they are trying to make it more difficult by going off of the 2 dowel holes.
