Plane, Circle, Width Alignment ???

RIDER
I have gained so much over the years from the contributors of this forum. Thank y'all for sharing your wisdom, knowledge, and experiences!

With that said, I would like your opinions on the attached crude drawing. It's third angle projection and in accordance with ASME Y14.5M-1994. The material at it's thickest point is 1 1/4". The total length of the part is 60". Here are the questionsRelaxed

1. How would you align this part for the position and profile call-outs back to ABC?
2. Since B is a huge diameter and C is a width, what would you use to rotate to?
3. PC-DMIS can't solve a constructed line from a circle/cylinder (B) to a width/mid-line/mid-plane (C). So what would you use instead to comply with the standard and satisfy the software?

There's some dissension here with regard to designer intent as well as compliance to the standard.

Thank y'all again for taking the time to share!!!

  • Following "if it can then it must" I would level to datum A, rotate to datum C (because you can not rotate to B), translate Z axis to datum A, and translate X and Y axis to datum B. I may be wrong (and please let me know if I am) but that is where my logic takes me without trying to construct a rotate between B and C.

    Out of curiosity, does any of the GD&T have a modifier on any of the datums?
