[v8i c++] mdlMesh_intersectDPlane3dPolyfaceMesh

Am I doing something wrong here?  

mdlMesh_intersectDPlane3dPolyfaceMesh is not returning anything..

Thanks ahead of time!

std::vector<DPoint3d> Get_MeshSegments(MSElementDescrP MeshHdr, DPlane3d Plane){

		EmbeddedIntArray        *pIndices = jmdlEmbeddedIntArray_grab ();
		EmbeddedDPoint3dArray   *pXYZ = jmdlEmbeddedDPoint3dArray_grab ();
		EmbeddedDPoint3dArray   *pIntersectionXYZ = jmdlEmbeddedDPoint3dArray_grab ();
		int                     blockSize = 0;
		std::vector<DPoint3d>	Results;

		if (   NULL != pIndices	&& NULL != pXYZ	&& SUCCESS == mdlMesh_getPolyfaceArrays (MeshHdr, pIndices, NULL, &blockSize, NULL)){

			mdlMesh_intersectDPlane3dPolyfaceMesh(pIntersectionXYZ, NULL, NULL, &Plane, pXYZ, pIndices, blockSize);
			printf("%d\n", blockSize);

			int ArrSize = jmdlEmbeddedDPoint3dArray_getCount(pIntersectionXYZ);

			printf("Count: %d\n", ArrSize);
			for(int i = 0; i < ArrSize; i++){
				DPoint3d p;
				jmdlEmbeddedDPoint3dArray_getDPoint3d(pIntersectionXYZ, &p, i);

				Results.push_back(UOR_To_Point(p));
			}

		}

		jmdlEmbeddedDPoint3dArray_drop (pXYZ);
		jmdlEmbeddedIntArray_drop (pIndices);
		jmdlEmbeddedDPoint3dArray_drop (pIntersectionXYZ);

		return Results;
	}
