API Reference > geometry-core > Curve > RegionOps > splitPathsByRegionInOnOutXY splitPathsByRegionInOnOutXY MethodStatic Find intersections of curvesToCut with boundaries of region. Break curvesToCut into parts inside, outside, and coincident. Return all fragments, split among insideParts, outsideParts, and coincidentParts in the output object. splitPathsByRegionInOnOutXY(curvesToCut: undefined | CurvePrimitive | CurveCollection, region: AnyRegion): { coincidentParts: AnyCurve[], insideParts: AnyCurve[], outsideParts: AnyCurve[] } Parameter Type Description curvesToCut undefined | CurvePrimitive | CurveCollection region AnyRegion Returns - { coincidentParts: AnyCurve[], insideParts: AnyCurve[], outsideParts: AnyCurve[] } Defined in curve/RegionOps.ts Line 454 Last Updated: 11 June, 2024
