    Do you mean something like this?

    I used a curve driven by a cylindrical equation and a swept blend. There are other ways... for instance you could use the trajpar variable to perform a variable section sweep while rotating the hex shape.

    In fact, I like that second way better (it's more flexible and robust)... but no one ever uses a Swept Blend so I figured I'd dust it off for this example. I've attached a file to play with (Creo 2 format).

    Thanks..

    PS: Edit the curve equation. By changing the value in red in the line that says: theta = t * 360 * 1 you can add more turns. For example, change the line to theta = t * 360 *5 to add 5 turns.

    Hi,

    I guess you have to generate the hexagonal trajectory outside of Creo into so called IBL file. Then you will be able to create a curve in Creo using this IBL file.

    Inside attached TXT file you will find a link to web page containing info about IBL.

    I would not go with an IBL, this entire thing can be done in Creo. John's suggestion is good. Amy of Vladimir Palffy's work with trajpar and variable section sweeps is also applicable. I'm on the road at the moment but I will link to some pertinent threads when I get to my computer.

    Thanks,

    Ah... like I said... go to Vladimir Palffy's blog. You can pretty much make anything into a spring using his technique. It's a bit of what John Pryal suggested with the addition of a straight curve. The technique uses a variable section sweep and the trajpar variable to create a complex curve...

    All the credit goes to Vladimir... he's quite the Creo genius.

    Thanks...
