Proper alignment

wrangler325
Hi team,

I have attached partial print and would like some clarification on what the alignment should be specifically for the 3 holes to A/D-E/D .
  • Datum -A- Plane
  • Datum D-E line
  • Datum -D-

Specifically, I want to know where the X and Y origin should be based off this print.

Thanks for any help.

Greg.

  • Measure plane for A
    Align/recall startup
    -Level Z to A
    -Origin Z to A
    Measure circle for D
    Measure circle for E
    Construct line between D and E centroids.
    Align/recall previous
    -Rotate Y+ to D_E line
    -Origin X and Y to centroid of D
    -Offset Y+ by the radius of 8.480" BASIC dim (4.240")
    You have your datum structure for that measurement

    How are you interpreting datum D's use as the tertiary datum? IMO, it would make more sense to just put datum D on the 2X pattern and only reference datums A and D, and that's essentially what you did here, but I don't think it's drawn that way on the print. I may be wrong though...
