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!!!

  • As a radius, B has a center point. Clocking then is from B (center point) to C (the midplane/line/point of the feature of size C).

    Explain to me why you are using B-C to rotate to when C can rotate by it's self. My thinking is that since B can't rotate by it's self but C can, you should use C. Now if C was also a circle and couldn't rotate to either B or C alone, then I would use B-C to rotate.

    I know the above sounds rude and dictating but I don't mean it that way. I am genuinely wanting to know if my thinking is wrong and I'm explaining what my logic is. Read it for what it is with no attitude or emotion attached. One thing I hate about typing is that you can't convey attitude or emotion.
