Unequal bilateral positioning 1

[JLang17]

I have a hole that is called out with vertical positioning +-.005 and horizontal positioning +.006,-.001. Is there a way to use a positional tolerance (or any GD&T method) to allow more movement in one horizontal direction than the other? Or does the hole need to be centered in the tolerance zone?

Simply put, the hole can move left .001 and right .006. How do I show that with GD&T?

drawoh,

If I send something out to be fabricated with rivets, I want to control the location of the rivets. I need them some distance apart. I need them some distance from edges. I need it to look like the fabricator had less than six beers at lunch.

Why should I not use positional tolerances to do this?

As KENAT notes, I apply MMC when I need it. This case, I do not.

GD&T is used for all holes and removable fasteners, not permanent fasteners.
