Distance of bottom of theoretical sphere to plane

Good morning PC-DMIS forum,

I am a little newer to CMM programing and hoping I can get some help in this endeavor.


if you can see , the cylinder size (highlighted in blue) is .711-.715 with a theoretical gage ball of .709 going into the cylinder the other dimension highlighted in blue is a distance from the bottom of the theoretical gage ball to a plane.

I have tried making the theoretical sphere using the cylinder and distancing the sphere to the plane but it comes out off, even when i use the "minus radius" button in distance. I believe I can accomplish this measurement, but feel I am missing a piece of the puzzle.

Can anyone here help me solve this issue? it is the last part of a rather robust program the captures most of these dimensions. if it helps the part is orientated so the plane that is being measured is facing up in Z.

Thank you all for helping me out with this.

  • That sounds promising, I tried figuring out how to implement this and I am unsure how to construct the plane where it is perpendicular to the cylinder, I can only get it parallel for some reason.

    Is there any way you could tell me the steps to achieve this?

    once again, thank you for sharing this knowledge
