Is there a way to shrink wrap the outermost layer of stuff in Rhino?

Kind of like what this plugin supposedly does (I haven’t actually used it) In lieu of scripting, is there a way in Rhino to isolate or retopologize only the outermost geometry or faces of what’s in the workspace such that it can be easily exported to *.STL or even shot over to a subdivision mesh modeler for further visualization uses? Hot diggity, this would be so dang useful.

Thanks forum.
