Thanks for the help, also to Bernard.

To illustrate what I am looking for please see povray.binaries.images,
"Antennas & missing cable".

The routine you posted gave me some ideas, but I still don't get it.

What I need is a cable connecting the two bright red cable ends already
shown in the picture. The vectors of these points are known, but as you can
see they are neither in origin nor in the same plane.
The cable should go from the vertical part still somewhat lower, then gently
curve upward until horizontal and join the other end. Later on a second
similiar cable is to be added to the other side.

My guess is I need something like a 3/4 circle, slightly bent out of a
plane. Something like a small part of a spiral. Now I know how to make
spirals (I think), but how do I tell it which two points to join in what
direction?

Thanks,
Ekki
