I am creating a new cable using the SW routing feature (first time trying it).  When I edit the spline sketch the cable looks fine (see first image below).  When I exit the sketch, however, the cable profile becomes distorted (see 2nd, 3rd, and 4th images below).  I've tried varying the spline trajectories but that hasn't solved the problem.  Anyone have an idea why this is behaving like it is?
