    Burunduk replied to the thread Datum callout question.
    Not sure if you mean the same thing I'm about to say, but: CIrcled M after the tolerance value in the FCF means a tolerance at MMC and...

    Burunduk replied to the thread Datum callout question.
    Modifying tolerances to apply at MMC and datum features applied at MMB allow to make inspection simpler than when not using the circled...

    Burunduk replied to the thread Fuel Rail Supporting Mounts.
    April fools jokes aside, It seems to be common to refer to the use of geometric characteristic symbols placed in feature control frames...

    What's the problem with the term GD&T? It has been standardized for many years now to mean General Dimensioning and Tolerancing...

    Burunduk replied to the thread Fuel Rail Supporting Mounts.
    Lots of dimensions and a lot of them can't be evaluated reliably if the general +/-0.1 from the note applies to them. Now you have no...

    yes Burunduk if the hole had to be precise for a press fit , then RFS would be prefered

    greenimi, The function of MMC position is to allow clearance fit with a feature that is fixed in a mating part that interfaces with the...

    Burunduk replied to the thread Datum callout question.
    So, you are asking about RMB (the datum feature material boundary modifier), not about RFS (for the mutually locating position tolerance...

    Burunduk replied to the thread Datum callout question.
    greenimi, RFS would be interpretable. In terms of the requirement it's two dia. 0.15 mm coaxial cylindrical tol. zones in which the two...

    mfgenggear, Yes, I'm not sure why there is the basic dia. 39, maybe OP was thinking to control it with a general profile? Anyway I'd...
  • Burunduk
    Limited length or area dimensions are a lot like datum target area dimensions. You don't control their variation on the part drawing...

    Or as shown in these examples... The first one is the same as using a Continuous Feature modifier for the 35+/-0.1 diameter.
