A geometric tolerance applied to a subfeature has a value greater than the parent feature.
A geometric tolerance applied to a multisurface feature applies to all its subfeatures. When you apply a related geometric tolerance to a subfeature, the specified value must be less than the geometric tolerance values applied to the parent feature.
To resolve the issue, change the subfeature tolerance value to be less than the value of the related tolerance that is applied to the parent feature.
