If a Modeling Application statement allows you to specify a distance or angle tolerance value and you do not provide one, the default is the value set in the Unigraphics option for Preferences—>Modeling. You can read and set these tolerance values using the &DISTOL and &ANGTOL GPAs.

If a Modeling Application statement performs an approximation and that statement does not allow the minor word TOLER, the system uses the tolerance value set in Unigraphics.
