Location Is Not Fully Constrained
Not all aspects of location are constrained by the tolerances that have been applied to the
feature. Each feature in a model must have its location constrained to fully define the part requirements.
The solution to the problem may to be edit the feature and select a suggested
geometric characteristic symbol (GCS). Note that the GCS must reference a sufficiently constrained
datum reference frame (DRF) in order to fully constrain the feature location. If a sufficient DRF is not available, you may have to add a new one to the model.
