    There is a spiral function in SW under insert\curve\helix, not sure if
    it fits your equation.

    Or I have a macro that plots an equation as a spline.

    go to Macro Library link.

    Hi! Sir

    Thank your support very much .

    When I run macro " eqcurve - input an equation (quadratic or periodic
    functions) and SW creates a spline curve (Matt Lombard) ", It interrupt by
    this " Set selmgr = Model.SelectionManager() ". Could you give me a hand ?
    Please tell me how to troubleshooting.


    My PC SW's version is solidworks 2004.

    Thanks
