&DISTOL
Sets/reads the distance tolerance used in the Modeling Application for many curve and sheet body creation and editing operations.
Statements that specify a distance tolerance using the optional minor word TOLER will override the distance tolerance value set interactively in NX using the Preferences->Modeling option. If one of these statements doesn't specify the optional distance tolerance value, the system uses the distance tolerance value set in the NX option.
