Yo Tommy-
Yeah, pretty slick. My only reservation relates to a lot of similar programs for other applications and that is it seems guys just coming up are depending on electronic sources without a strong grasp of the concepts [like right angle projection for template development] these numbers are generated from. A solid grounding in applied geometry and right angle trig makes the world a simpler place when you run up against a real head scratcher. But I do like the efficiency of the tool you found. Have you checked it for accuracy yet?
