You shouldn't be glossing over anything. Basic dimensions are used to validate part geometry as defined in feature control frames.
If there are features that have basic dimensions defining their location or orientation without an associated feature control frame, then the print IS improperly dimensioned. If, as previous respondents have postulated, the engineer is indicating basic dimensions as meaning reference dimensions, the print IS also improperly dimensioned.
Good luck, though, trying to get engineering to admit when they improperly draft things. "I've always done it that way." is their mantra.
