Simultaneous requirement

Can anyone tell me what exactly this command does? Using 2020 R2
Other than putting SIMTOLX after my FCF I don't see anything different then if I didn't use it.

  • I wrote a dummy program using the surface of my Rayco plate as +Z and 2 posts as and [C].
    the first set of dimensions are using the SIMTOL, the second set are the same features without the SIMTOL but with the same result


    Somebody more knowledgeable would have to confirm this (perhaps neil.challinor ), but I believe if your considered features are OOT even after optimization, the result will be reported without any optimization.

    To test this, report the same three dimensions with the material modifiers removed (simultaneous tolerance need not explicitly apply) and check to see that the values are the same.
