Position trihedron

I have a circle with a true position callout and its datum precedence is the same as my alignment. So why would there be a separate trihedron for it with the Y and Z axis switched?

  • I am not totally sure of the order of precedence for the TP evaluations, the GD&T alignment might start with your primary datum as alignment for X or Z, this will not correlate with your alignment, but if you choose to the reporting according to the current alignment - it should match.
