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? Theoretically you could create a plane using the start points and end points of A and B and that would be used as datum for this centerline. But it makes no sense, really.
