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!!!

  • I check formed parts all the time. Not saying that's what you have but.... When the RAD is formed and then machined at another op you have to use an iteartive alignment. If you don't your dead in the water.... If your RAD is actually machined the center point of B might be more stable but still wiith the arc segment size I think thats heading to disaster.
