This is what I am using to model string. It's essentially a twisted 4 sided shape. I probably should have done it using 6 sides instead. I put two of these back to back with the grey pattern matching up, then replicated to get the length needed. LMK (...) (23 years ago, 10-Apr-02, to lugnet.cad.dat.parts)
