Intermediate End Feature and Connected Intermediate End Feature generating part.
According to the design, only one IEF can generate base components/parts. We will allow one feature to generate the base and another to generate the mating parts.
This problem might occur when the rules followed for part generation fail.
The reports generated may not be valid.
What You Should Do
The problem will be fixed as soon as the feature is re-computed. To trigger a re-computation, one of the adjacent features can be modified.
