Does anyone know, postion tolerance usage tips.
For example I know using for hole positioning.
But attached symbol used for surface, what does it mean?
Best regards.

I suggest having the ASME library at your business.

According to ASME Y14.5M-1994, the US Dimensioning& Tolerancing standard:
"2.1.1.1 Positional Tolerance Method. Preferably, tolerances on dimensions that locate features of size are specifieed by the positional tolerance method ..."
So it's not just holes although that is perhaps its most common application.
Without seeing the 'surface' that FCF was pointing to on the drawing it's difficult to say what it meant. The fact it doesn't have a diameter symbol means it's a square position zone rather than circular as often used with holes, if that helps.

-Axis of a cylinder
-Centerplane of a slot or slab
-Center point of a sphere
That's it. There is no application of Position to surfaces. Location control of surfaces is accomplished using Surface Profile.
