I don't have NX 8.5 installed.
But I guess yes, this options is available while simulation an external NC Code as Display Cutcom as Contact Contour.
Do i understrood it right?
ISV uses the correct values when using getRadCorrection(), but motions is not corrrect.
And with a different tool same operation you also get correct values when using getRadCorrection() and
motions is corrrect.
Then sorry, no idea maybe talk to GTAC.
