CETOL 6 Sigma problem when analysing dimensions variations in a lens
Recently I`ve tried analysing a variation of a dimension in the lens. The variation of the dimension that I try to analyse is 2.036 (refer to the attachment). The dimension that affect the measurement chosen is 18.5±0.2. Hower, CETOL 6 Sigma does not recognize the dimension 18.5±0.2 (CETOL usually offers automatically to choose the dimension which affect the measurement). I wonder, why it does not recognize it. Could anybody help?
P.S. I do know that it is a pure simple case and can be done by hand but to have a notion of how CETOL works in such cases (or how to solve such situations) will help analyse more complicated cases.
