I am a beginner and I have problem in reaching toolpaths for an open pocket. I follow a step by step exercise in a mastercam v9 workbook by R. Cozzens and somewhere I guess I'm making a mistake. After inputting all pocket parameters just like the book says to do. I click OK and wait for the toolpath to appear but all that happens is -> Mastercam window says: processing, please wait. It's a simple operation and I'm really confused why there is no response from the program. Can You please tell me what can be causing this "halt" ?
