In using laser cut files directly out of Rhino, I consistently found the need for a command similar to "overkill" in Autocad for Rhino. In addition those pesky overlapping surfaces which create render artifacts and kill render time just needed a quick fix. Though it is only able to detect points, curves or surfaces, future adaptations for polysurfaces and possibly meshes are in the works. However for what it does this Rhino Script has been helpful. Any suggestions for additional types of geometry to be checked, or additional features are more than welcome.
