Profile of a Surface Callout on this Drawing

[Bobh@pte]

Please settle this dispute with this profile of surface callout,
Someone out there will know the exact interpretation.
See enclosed jpeg. I am saying we have a +/-.0005 tolerance band for all surfaces in this view, unilateral, Because of the all around symbol.

Anyone see this any differently?

I agree with what you said except that ±.0005 is bilateral, not unilateral. Tolerances for profile symbols are always equal bilateral unless otherwise specified.

I knew that, I agree, I fumbled the lateral.

Thanks for your input.

Someone was trying to bleed more tolerance out of these parts than they were allowed.

I fumbled the lateral.

That sounds like a football reference.

Right. The all around symbol isn't what makes it bilateral.
