    Modeling a strand - Twisting a sweep along a helical path - Help please!

    Matt Hoffman

      Hi all -

       

      I've had a very frustrating problem the last few days that I can't get figured out. I need to model a 3 x 7 strand. The 3 means there are 3 wires twisted together into a strand - like this:

      1X3 Strand.JPG

      And then 7 of these "3 wire" strands are then wound together, with 6 fitting snuggly around the edge of the middle 1 (like a hexagon with something in the middle)

       

      So, I'm starting with the above image, then going into something like this:

      Sweeping along a helical path, which I would then pattern 6 times around the central one.

       

      BUT, if you can see the problem... the outer strand won't "twist" like the central one! When I try to "twist along path" for the sweep, it says "sweep operation failed to complete. Smooth path is needed for sweep with twist"

       

      Please help! I can't figure out what this means or what the problem is. Is there another way to accomplish this without "sweeping with a twist"? Any help is much appreciated.
