Does calypso automatically calculates MMC?

Does calypso automatically calculates MMC? If so, how does it work exactly? or is there a formula needed? I've try putting my own formula which it has given me the right tolerance but not sure if this is the right way of doing it.

Yes, but i dont think Calypso gives bonus on secondary or tertiary datums as that usually falls into datum shift territory (I may be wrong)
So when you have mmc added, the tolerance shown will be MMC + Bonus, so itll change every run, does that make sense?
So you got .010" + .0025 bonus, so the tolerance will show as .0125, but the next run you get .0028 bonus so the tolerance will show as .0128.
Calypso will not separate the base tolerance and bonus the way that other software does.
I found myself answering too many questions of "how much bonus do i get" and "Are you sure this calculated right" so i used PCM to add a note in my "Comment box" to show the Base+Bonus on all my dims with bonus.

Its a real archaic system i have going on, but for me it works.
If you're handy with PCM you could probably shorten it up quite a bit, but it works so i keep using it.
if you want ill walk you thru it.

You do have PCM right?

I do a similar method as you do but first I test if the diameter is below the allowable diameter tolerance. If it is there is no MMC it is 0.000. In this example the diameter tolerance is 3.199 +/- 0.003

i=getActual("Stator Bore Dia").diameter
if i<(getNominal("Stator Bore Dia").diameter-0.003) then
Var2=0.0000
endif

if i>(getNominal("Stator Bore Dia").diameter-0.003) then
Var2=getActual("Stator Bore Dia").diameter-(getNominal("Stator Bore Dia").diameter-0.003)
endif

I find this works well

I thought that it automatically showed you the tolerance with the bonus tolerance to the right of the original tolerance when using the Custom Printout?
