API Reference > geometry-core > Curve > CurveExtendOptions CurveExtendOptions Class Logic for deciding how a curve may be extended for closest point or intersection searches. Methods Name Description correctFraction(extendParam: VariantCurveExtendParameter, fraction: number): number Static * if fraction is between 0 and 1 return it unchanged. resolveRadiansToSweepFraction(extendParam: VariantCurveExtendParameter, radians: number, sweep: AngleSweep): number Static Adjust a radians value to an angle sweep, allowing the extendParam to affect choice among periodic fractions. resolveVariantCurveExtendParameterToCurveExtendMode(param: VariantCurveExtendParameter, endIndex: 0 | 1): CurveExtendMode Static Given an ExtendParameter, isolate the particular CurveExtendOptions in effect at an end.
