    GN is Min Circumscribed
    GX is Max Inscribed

    Can be used with the SIZE feature within PC-DMIS (2017 R2 and above I believe...)

    Help file states:

    The Size command supports the following modifiers that are defined in the ISO 14405-1 standard:
    • (LP) - Two-point size
    • (GG) - Least-squares association criterion
    • (GX) - Maximum inscribed association criterion
    • (GN) - Minimum circumscribed association criterion
    • (CC) - Circumference diameter (calculated size)
    • (CA) - Area diameter (calculated size)
    • (CV) - Volume diameter (calculated size)
    • (SX) - Maximum size
    • (SN) - Minimum size
    • (SA) - Average size
    • (SM) - Median size
    • (SD) - Mid-range size
    • (SR) - Range of sizes
    • (E) - Envelope requirement
    • ACS - Any cross section or sections
    • SCS - Specific fixed cross section or sections
