                                        - Same as ERR or 2 with
                                            the exception that only warnings are issued.

                                        - All non-zero length gap elements that have a prescribed
                                            coordinate system are checked for misalignment of the
                                            gap prescribed axis (x-axis of the prescribed coordinate
                                            system) with the vector GA->B. Angles larger than 30
                                            degrees produce warnings, angles larger than 60 degrees
                                            produce errors.
 
                                    
                                    
                                        - NO or 0
 
                                        - No gap CID direction checks are performed.
 
                                    
                                    
                                        - REV or 3
 
                                        - The orientations of the vector GA->B that are generally
                                            opposite to the prescribed axis are also accepted. The
                                            tolerance levels are the same as for the default case,
                                            except that they are measured from either 0 or 180
                                            degrees reference angle.
