C(uriosity) Q(uestions):

If I create a datum point far removed from model surface geometry is the effective tolerance for all subsequent
features markedly increased? Creating the point will expand
the (Info / Model Size) part bounding box. Is it this same
bounding box that's used for tolerance calculations or
another that's determined by (and not exposed to the user)
surface geometry?

Is there a way to, other than manual calcs, to determine the effective tolerance being used at any given time in the model?

There is a 'geometry dependent factor' involved in effective tolerance calcs. I ~think~ (really don't remember) that ~.8 is a number I've come up with based on export resolution values. It seemed to be constant for simple prismatic parts or spline surf parts. Is there any known documentation available to explain the factor?

And finally, regarding export tolerances; the effective accuracy applied to a feature depends on model parameters at the time of creation (if I understand the process correctly). When geometry is being processed for translation is the same 'at that time' tolerance applied or is the tolerance in effect at the model's final feature used? And, this is the value recorded in the translation?

Trying to get a handle on some of the concepts.

TIA
