i know how to scale my helmet the only trouble is that i cant scale it, this is bescause i dont have a menu option say 2D patter window , the only options i have are file, view ,settings,etc.
That's your problem, Viewer doesn't scale. Try downloading the Designer from the Tamasoft site, you wont be able to save without buying a license but you will be able to scale and print with the unlicensed version
