Thread parametric

This is supposed to be the beginning of a screw and nut, but it wasn't so easy to grasp how OPENSCAD functions, especially when it comes to visualizing rotating polyhedrons. At this point, we can only create teeth profiles with polyhedrons or other basic forms in openscad and then rotate them to produce a thread. It's true that my ten-core i7 Intel processor has to process the Krivky.scad file for 2 minutes on the smaller version and 17:41 minutes on the longer version using cgal. Following Philipp Klostermann's post, I started analyzing different approaches. It's not easy to imagine the steps of computation with let statements, so it takes some time to modify the initial post to transform it into a helicoid equation. The result can be seen in the "screw_extrude_EaVF.scad" file, which is Philipp Klostermann's streamlined code tailored to my needs. If you want one, I found a library for threads downloadable at http://dkprojects.net/openscad-threads/.
