helo i wonder is there a way to change radius of rings in art cam since radius that make on my weding rings is smaler thhan artcam''s so when i make 5mm wide ring i need to put about 7mm wide ring in artcam but thats all gamble since i make difrent radiuses.. Since in serbia u sell weding rings per gram. like 1gr is 30eur so ppl mostly buy bout 6gr for 2 weding rings so i need to make small radius to get that weight but artcam has only big radius for rich ppl so i was wondering is there a way to make my own radius that i need .....
