Feature type

Nominal size

Actual measured size

Lower size limit

Upper size limit

Geometric tolerance

Material condition modifier

Measured position error / deviation

Optional X deviation

Optional Y deviation

For holes, MMC is the smallest size and LMC is the largest size. For pins, MMC is the largest size and LMC is the smallest size. Position from X/Y uses diametrical true position: 2√(x²+y²).
