True Position ISO 2768-m

I am currently programming a job from drawing with a hole with no true position specified, it has boxed dimensions which would imply a true position. I've notified the customer to ask what the true position would be and they said I should be able to get the true position from the ISO Spec?

To my knowledge the ISO specification used being ISO 2768-m does not specify a true position to use for boxed dimensions with no positional tolerance, this is usually illustrated on the drawing in a tolerance frame around the hole call out? I'm looking to reply with words to that effect, am I right to say this?

I've checked the standard and I can't see anything on this, any advice would be greatly appreciated

I think you're right, a general tolerance can't be applied to a boxed dimension.
Maybe the customer wanted to use 2768k, for geometric dimensionning, but there's nothing about location in 2768-2...

Hi JEFMAN,

I did contemplate using K at its tighter end as the medium tolerance but like you says it doesn’t cover position I might just go with that if I don’t get a better response from the customer, it sounds the most plausible option The Link to the DIN ISO 2768 you have there in your latter post is the same one I've been using
