CSP Textron_386-100473
Side holes in radial pattern, needs secondary alignments; or report with polar tolerance zone shape
CSP HETP000014
Datums A and B, with datum B being 2 holes that form a diameter for the center.
CSP 20048
ADC shows that datum D sets XY, but C is only rotation, because of order of precedence.
Show how it could be redrawn so the .3746 holes can both become datum D, using a best-fit. This minimizes bias.
Comment on how datum B is in-line with the width dimension, but C is not. The basic dimensions coming from the lower left corner indicate that B and C come from the lower and left sides only.

slightly different, with ADE clocking from second hole.
