Lets just see if we can walk thru this part without trying to sanitize the print and post it..... This is not called out to ASME or ISO or any DIN standards ? It s a German automotive print from the looks of it so I am assuming ISO or DIN ? I am not familiar with either one at all. I do have a ASME Y14.5 certification so I am not totally lost in the GD&T. The question is I have composite position call out that the datums are different in each segment. I know in Y14.5 this is illegal as they have to follow the same order in a composite. Simple -X-Y-Z- & -A- Datum reference frames. Z is top plane , X is side plane and Y is a Hole, A is a hole ( hehehe ) The callouts are all different but as an example I have ( 1st line of composite ) 1.5 to X Y, ( 2nd line ) 3.0 to Z and ( 3rd line ) 1.5 to A. My initial thought was if these were dual single segments I wouldn't even be questioning this. It makes sense that way. Is this a legal callout as a composite ?
