We have several seats of NCSimul and we have been using it to simulate complex 5 axis trimming since 2010. Before making the purchase we evaluated several of the ‘popular’ products (VeriCut, ICAM) and NCSimul was the best product for us. Spring Tech is new on the NA market and they have a relatively small team in the US, but they offer first class sales and tech support. I highly suggest you try/demo ICAM, VeriCut and NCSimul before making a purchase. After evaluation the decision was an easy one for us. Alex
