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.

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