Tolerancing issue: "Nominal Criterion cannot be computed"

Hello everyone! I am trying to perform a study of tolerances in an optical system in which my criterion is the RMS Spot Size. If possible, I would like the GEO radius for one of the fields not to exceed a certain value (with reference: vertex). In any case, it is not possible for me to execute the tolerancing because of a problem that I show you here: “Nominal Criterion cannot be computed”.


Do you have any suggestion?

Thank you!

I have found that it is due to the black box I am using from a ZAR file so tolerancing can’t be run with black boxes on the design, just in case someone has this problem too.
