Multiple catenary gradually changing direction, like pointing to a plane

Hi guys,

Say that I need to create catenaries between points that instead of having a single direction vector, they actually point towards a middle plane, so that the upper one has a direction and the lower one has the opposite direction.

Any suggestion?

You could define a vector for each catenary? Two examples attached do so, the second one remaps the length values by vector length a bit so it's more even (if you look at a cross section through the centre you can see that the first option gives a strange kink).

Alternative option for the 3 point, although I don't think it's right option for this, would use a 3 point arc and scale the middle geometry. This is not to be confused with a catenary though.
