I used it in my long search for cam programs. I found that this is what i would recommend for use along with mach wizards as a comparable to the 1+k software cam systems. It is really easy to use I downloaded the software and literally within 5 minuets I had my first g code milling on the machine from a imported soildworks stl. The one drawback is the possible necessity for scaling a generated stl file and the lack of specification for choosing a custom type of stock. In the end I ended up going with Mastercam due my ability to get my hands on it.
