Coax Cable in Creo Cabling

Does anyone have any guides/tips on how to set up coaxial cable in Creo Cabling? I know there's a way to set up multi-conductor and ribbon cables, but was wondering if anyone has done coax-style cable.

In a second, somewhat related question, I was wondering if anyone had ideas on how they would model the cable as pictured below. I was able to model it, but I used a lot of curves, sweeps, and a helical sweep in order to do the coiled area.  It was a mess and I feel it should have been a simpler process. This model just represents a coax cable between two offset connectors with a service loop.
