closestPoint Method
Search for the curve point that is closest to the spacePoint.
- The CurveChainWithDistanceIndex invokes the base class CurvePrimitive method, which (via a handler) determines a CurveLocation detail among the children.
- The returned detail directly identifies fractional position along the CurveChainWithDistanceIndex, and has pointer to an additional detail for the child curve.
