API Reference > geometry-core > Curve > CurveFactory > assembleArcChainOnEllipsoid assembleArcChainOnEllipsoid MethodStatic Return a Path containing arcs are on the surface of an ellipsoid and pass through a sequence of points. Each arc passes through the two given endpoints and in the plane containing the true surface normal at given fractionForIntermediateNormal assembleArcChainOnEllipsoid(ellipsoid: Ellipsoid, pathPoints: GeodesicPathPoint[], fractionForIntermediateNormal: number = 0.5): Path Parameter Type Description ellipsoid Ellipsoid pathPoints GeodesicPathPoint[] fractionForIntermediateNormal number fractional position for surface normal used to create the section plane.
