We have been using the program for a year and are very satisfied. SmartWOP is easy to learn. Design with Sketchup or Spirit, create construction and machine programs for BHX 055 to 95% with Smartwop. No programming errors, programs fit, lists of materials are clear. The program is constantly being developed, suggestions are accepted and implemented. T elephone support is excellent, friendly and competent, the carpenter's language is spoken. I'm excited, keep it up!
