Answer: Regardless of feature size (RFS)
Step-by-step explanation:
It is a pre-selected condition for every geometric tolerance which is the second rule of GD&T and it requires no repairs, it is adopted when size feature has no effect on defined tolerance. RFS implies that GD&T callout is not dependent on size dimension. Least Material Condition (LMC) cancels out this rule.
•Reasons for using RFS.
1. It can not be easily determined.
2. It can be used anytime but can be ignored if it is specified.
