Spline Control Tips

I'm often finding that my flexible tube routing componentsappear to lack a "natural" look. Instead of smooth flowing 3Dpaths, they appear more abrupt and poorly directed.

Are there any good tricks or methods that you guys use to get your3D tubing paths to flow in a more natural way. Tangentrelationships to connection points still look like crap and takeforever to get semi-realistic.

Number of control points, min radii etc all have an effect I'msure, but I just can't get these things to look right. Hardly ashow stopper as far as production concerned, but would beinterested in hearing ideas anyway.SolidworksRouting
