Thread cutting script - WIP

Hello Martin,

Really cool stuff. How did you manage to knock off the two sides of the triangle that are perpendicular to the cylinder before the cutting operation? I never could get that to work without knocking off the edges so there wouldn't be that sort of self intersecting situation and the cutting surface wasn't skimming to closely to the cylinder. Of course that was a manual operation, perhaps the scripted operations behave differently?
