API Reference > geometry-core > Curve > CurveChainWithDistanceIndex > moveSignedDistanceFromFraction moveSignedDistanceFromFraction Method Implement moveSignedDistanceFromFraction. See CurvePrimitive for parameter details. The returned location directly identifies fractional position along the CurveChainWithDistanceIndex, and has pointer to an additional detail for the child curve. moveSignedDistanceFromFraction(startFraction: number, signedDistance: number, allowExtension: boolean, result?: CurveLocationDetail): CurveLocationDetail Parameter Type Description startFraction number signedDistance number allowExtension boolean result CurveLocationDetail Returns - CurveLocationDetail Defined in core/geometry/src/curve/CurveChainWithDistanceIndex.ts Line 509 Last Updated: 13 June, 2024
