correct gdt symbol to use
(OP)
hello - always a wealth of info here - i have a small eccentric shaft that was sent to our company from our overseas manufacturing facility - the drawing has the main shaft dia. as the a datum & the eccentric dia as being parallel to a & true position to a w/ a tolerance - this seems to be incorrect to me - i believe that the eccentric dia. should have a circularity datum to the main dia. and/or a parallel datum symbol - any thoughts on this - any info would be greatly appreciated - i cannot post a pic of the drawing do to not having access to the drawing at this time - thank you

The position callout works well. If the surface is anything other than cylindrical, then surface profile should be used.
