I would like to ask which CAD program you are using. I have Autocad 14 at work, with a 36" plotter. I am having trouble getting lofted curves into Autocad, and was wondering if maybe the program isn't suitable. Perhaps I should be using something like Mechanical Desktop? I'd be pleased to hear your suggestions. Thanks.
