i need help with a big part with iterative

pcdmisstudent
Hey guys
so i have this big part, that the datums are defined by 3 datums points (three holes with sample hits that i did iterative with). I then constructed three theorietical planes (alignment planes) and defined those as ABC. Then i measured all the different features on the parted and called them out using FCF position.
the program works well, but some of my results gets weirdly high.
Ill upload pics with the datum targets (see black circles)

  • First thing thats weird are these 2 planes. They re dimensioned with position to A/C (and perpendicularity).
    Theres also a linear depth callout on them and the depth/height of them are spot on.
    But the TP is measured at 1.9mm and 3.2mm (even tho they re both the same in height). THe nominal/measured values in the TP field are also really close to nominal so i dont know why the TP deviation is so high nor why they are measured differently

    You cannot have a Position of a single plane. For a position callout it must refer to a feature of size. I would ask what is intended for the callout since Position will not work in this instance.
