I use CamWorks & SolidWorks and found Calypso to be a pretty intense program to learn in four days . I like it although we do have problems with it , most of which went away with the new update . I greatly appreciate your attempt to help me . I'm just a broke hot rodder like most of us and I'd like to try to make something really cool . I'd pay for the files I just can't afford the $400 or whatever to join SEMA (although I'd like to).
