How to create Twisted wires

Geoff,

Are you trying to do this within Cabling automatically, or do you want a general modeling method? I don't remember this being an automatic feature when I last looked at the Cabling module a few years back, I may be wrong. Anyway, it can be done quite easily with a Datum Curve at the centerline of your cable and two (or more) Variable Section Sweeps twisting around the Curve for the individual wires.

When you create the VSS, you sketch a circle on an angled centerline going through the start point, then you vary the angle dimension using a Relation in Sketcher. For example, if you wanted 10 twists as in the above illustration, your relation would be something like sd4=trajpar*360*10.

If this method interests you, but you are unfamiliar with "trajpar" and relations like the one above, I can give you more details.
