": What if any rules apply to the Unilateral/Bilateral
: Tolerances for dimensions with Double Plus or Minus
: Tolerance?
: Example: 0.250 -.010 to -.020"

I'm not sure why one would express a tolerance as you have indicated , however I believe the dimensional rules are the same. Why not express this feature dimension as .240 - .230 ? or .230 +/- .005?
