I am in need of some PC-DMIS dimensioning assistance. I have a part that I am measuring that has multiple machined steps in it. They are not square steps however. They are using a ball mill to machine the transition between the 2 steps as shown in the picture.

radius to plane.jpg

The customer's dimension is from the end of the part to the intersection of the radius (measured as a circle and a cylinder) and the plane. I have tried measuring the upper plane and radius but because it is only a partial radius I am unable to offset the measured radius to acquire the intersection. I also tried creating a constructed line using the plane and the cylinder but the line would not intersect the 2 features in the correct place. I have tried everything I know to do. Please help if possible.

Thanks in advance!!!
