I am wondering if participating in the newsgroup would be an appropriate avenue for pursuing my problem. First I should say that I do not have mathematica and have never used the program. I am considering purchasing it if I can be assured it will do what I need. I need to create a part in a solid modeling CAD program that I using to design a machine. The shape of this part needs to be constructed from a helical spiral curve path with a variable pitch. While constructing such a path is beyond the scope of the CAD programit can generate such path from an imported excel spread sheet data file. My hope is that the spiral could be produced in mathematica and saved as a .csv file which Mathematica tech support has told me can be opened in excel and then saved an an excel file. It would be good to try exporting in .dxf as well. For me it would be prudent to test this theory before purchasing mathematica for this single purpose and so I am wondering if in joining the newsgroup I might be able to solicit someone to produce a test curve and file for me that I could try in my CAD program. The attached file illustrates the spiral shape. [Contact the author to obtain the file - moderator] If you could give me aopinion as far as joining the newsgroup to further this research I would appreciate it.
