r/GDandTdiscussions

I have a more complicated part than the one shown in the image. I've stripped it down for clarity. How do I dimension the position of the hole? There are no perpendicular edges to reference in the Auxillery view. Only the datums A, B and C to link it to.

Hi, I need some help with GD&T/geometric tolerancing on these drawings.
I’m mainly unsure how to correctly apply geometric tolerances to the functional surfaces/features of the parts. I already have some geometric tolerancing on the drawing but I'm not sure if it's correct.
