[QUOTE="Nena, post: 270748, member: 7861"] Working a few day's with this problem gives also a headache :D but if im thinking about the upper drawing it could be well perfect. Becouse it is a symmetric shape that is being done on a index. So one of the lines need to be exact from one side to the other side, also by the given degrees. But if i think about that, a drawing that does not have exact symmetric, the light ist breaking at the good spot. Mmmzz it logic but... If you measure in gemcad, you need to measure at the meetpoint and the tip of the pavilion. It says: 0,20372558 but you need to divide it by 2! Then you get 0,10186279 thats 0.102 ;) Greets [/QUOTE]
