i know some peeps that use it and i've tried to use it, well, by creating formulas and wizzards you can create whole elements with this. I've played a bit around but i don't really like the program.
Elementary creates elements based on math formulas. You'll need some more things then elementary ti create a whole coaster. Too bad that tyler took down his site as his book file gave a good overview about the whole thing for starters. But Matt is working on a new Site. Maybe you can ask him for the link cause I'm not sure if wws wants that I post the link since matt is banned. Or maybe I can also help you, just let me know.
