arrsurface = Rhino.GetObject("Select Single Surface, Note: Single Extracted Surface...", 8)
If IsNull(arrCurves) Then Rhino.DeleteLayer "Work" :Exit Sub
I can't grab a surface from a joined poly object, like "extract surface" does. Or like "Orient on surface" does you are able to use a particular surface from a poly object, or just a surface. I have a couple ideas in a way I might be able to use extract surface. But I thought I would ask before going off into left field.
