I am measuring how far apart 2 the centers of 2 cylinders are plus their radi. This is to see how wide this cavity is. So I selected distance measurement, clicked my 2 cylinders across an axis and then selected add radi. Is that calculation taking into effect the size of the cylinder? So if 1 diameter is larger than the other, that distance will be longer? That tolerance is huge with +/-0.020". I am also measuring the location of the centers of the cylinders with a +/-0.0025" tolerance which is failing. I'm having a hard time explain this to the designer who says the CMM isn't correct.
Yes, when you use ADD RAD it is using the measured Rad data, if you only have partial arc available, it can alter your size frequently and destabilize the width output.
You may need to determine the size, then use Fixed_Rad on the width measurements to increase your repeatability.
