Hi August...
Creo Cabling doesn't have a feature for this. You can automatically route the wires and give them densities such that they can mimic real-world twisted pairs. However, there is no inherent feature within the software to give you a nice twisted wire image.
The cabling package is more concerned with the connections being made between connectors and components. It's not necessarily trying to give you a true-to-life picture of cables/wires with real-world physics. That's asking a whole heck of a lot. I'm sure it could be done but the performance hit you'd take would make it useless. Give computers another 10 years and then maybe we'll have the processing power for that kind of on-the-fly geometry. Right now I think it's a bit out of reach.
However, you can certainly use the techniques Antonius linked (above) to help you model a small chunk of wires that appear twisted. Then you can use those as a symbol or graphic on the field of your drawing. In your cabling model, perhaps you'd just bundle everything together. This will eliminate the need to see individual twisting wires. The symbol/graphic you've created will provide a sample of what the wires will look like "in real life" while the bundled version will show up in your model for best performance.
Am I making sense here? Let me know if I'm talking in circles.
Thanks!
