This ratio of flange gap to average thickness of the component is compared with the tolerance value. The issue is identified if the difference is the same or less than the limit value.
Note: No Error will be reported if thickness does not exist or offset is not done.

Failed spot welds are reflected at reflect-plane and re-realized, if successful in realization, it is identified as an issue.

Issues will be ignored if surface offset is not executed and another spotweld exists at the reflected location.
