It would have been nice to have posted a short description in the very first post of this thread as to what the script does. Such as "I’ve written a little script, available on the (my)scripts page, to slice up a mesh in Blender and export the slices as shapes in a SVG file that can be cut on a laser cutter. The mesh should be a manifold solid.
I took that from the author’s blog after opening about 7 levels of menus. The first post on his blog mentions this update but still does not tell what the actual script does. He is assuming the everyone that reads the title know has use the script or knows just from the title what it does. I am reminded of my what my high school English Composition teacher told us the first day of class, “Assume NOTHING about your reader and start at the beginning, because you only have about 20 words to capture his or her attention and induce them to read on.”
