OK, I have a quick question for all the brains out there.

I am checking the perpindicularity of a shaft hole back to a plane. The cylinder is in the bottom of a pocket. I am currently using the extended length to project the cylinder up to my plane (A datum) The extended length that I am entering is the length of the shaft that goes into the cylinder (this length is the depth of my cylinder PLUS the amount needed to bring it up to my plane) Hopefully my picture will show what I mean.

I want to know for sure that when I extend the length, it is projecting it up to my A datum, my leveled plane. Am I assuming correctly? ( I hate ASSuming)
