[TRKUGNX]

Hi all,
Do you have using NURBS in UG CAM?
I know NURBS output is the best, Faster,short and smooht,
but the result depend some tolerans value,
I want to know, Which tolerance and parameters give us best result when using NURBS output in UG CAM?
exp. Cutting intol/outol tolerance and Machine Control/Motion output/Nurbs/ Fitting control and Angle tolerance - Join segments,???
Which parameters and tolerance value must be use for best result?

sorry, My english isn't good,

Thanks,
