I forgot, or I would tell you.....BUT I will tell you that it is the VERY most usless tool for the game. It is designed for you to use while making custom parts....not just look at parts already in the game. But it is so much trouble to use that everybody just goes ahead and puts the part in the game to see it, so if you are not making custom parts it is 100% usless.....if you are making custom parts it is 99% usless.
