• "Rule 2" (in ASME Y14.5M): RFS applies, with respect to the individual tolerance, datum reference, or both, where no modifying symbol is specified. MMC or LMC must be specified on the drawing where required
• RFS means that the geometric tolerance applies regardless of the actual produced size of the feature
