oompa, I don't see anything wrong with the "classic" approach you describe for determining point projection to a surface. Creating a ray and surface intersection event may even be preferable in some cases as it will record multiple ray intersections with the same surface. Otherwise you could just wrap up all your points in a closed polyline and project that.
