OK, I got a letter from my boss, the letter explains how a customer of our is checking a part we make. Their method differs from ours, I'm going to give their method (verbatim), I was wondering if anyone can tell me if PC-Dmis is being used to check this part based on the description I give?

1.) Take 9 hits on Datum A (plane) est. best fit plane

2.) Measure shaft holes (B&C Datums) using 9 hits on each to establish 2 lines intersecting the A Datum. A PLANE is created from these two lines. This now creates 2 intersecting planes Plane A, and Plane BC. (Can this be done in PC-Dmis? Can we take two lines and construct a plane between them? (it looks like they are picking up B&C as cylinders right?)

Or does this look the be done in another software package?

The way I do it is. (this was written by the previous programmer, so I hope it's right!)

1.) 10 Hits on plane (Datum A) Level it.

2.) Pick up Shaft holes as circles (B&C Datums) using 4 hits.

3.) Create points that intersect from circles (B&C) to Plane (A)

4.) Contruct a line from B&C Points.

5.) That line is my rotation feature

Is this equivalent to their method? Input?
