Upper management sent me to a Zeiss/Calypso demo yesterday. They setup and measure a part I have been measuring with PCD for over a year now with no issues and Calypso wouldn't report the true position because the FCF isn't Y14 compliant (according to aplications engineer at demo). I brought to his attention that the print doesn't refer back to Y14 and his responce was it is implied which I can understand, but why will PCD give me position to the same FCF as he was using?

Can you do it with Xactmeasure? Prior to Xactmeasure pc-dmis did not generate errors for non-compliant GD&T. With Xactmeasure you will get errors or just not be able to select the things you want if you are trying to build non-compliant position dimensions. Pc-dmis is very powerful and flexible, which also makes it susceptible to "misuse". It is up to the programmer to have sufficient GD&T knowledge to use pc-dmis properly.
As an aside, drawings that have GD&T symbols but do not state which standard governs the interpretation of those symbols is problematic. My company handles this by stating in our quality manual that if the drawing does not specify we default to ASME Y14.5M-1994. However this does not prevent us bidding on and taking orders for parts whose drawings are non-compliant because the customer is writing the check, not ASME. These are black arts we dabble in.
