File talk:Geometric dimenioning and tolerancing-hole.svg

The datum reference of C is not posible in the position geometric tolerance as there is no dimension from that datum. It is a throgh hole in this axis???

Datum C is the primary datum reference stating that the hole axis is normal to the datum. Secondary and tertiary datums are the A and B datums. — Preceding unsigned comment added by 58.251.138.56 (talk) 05:20, 13 December 2016 (UTC)
