This is another interesting idea, but it's unfortunately quite difficult to implement well with the structure of NURBS surfaces - that type of surface tends to be easier to calculate on a set of triangular meshed nodes and the method of solving it I think typically uses an iteration approach that slightly repositions the triangle vertices during the calculation process.

The way NURBS surfaces work is fairly different to that particular kind of process and so it would be quite difficult to make a NURBS type version of a minimal surface construction I think.

There is no built in support for minimal surface creation in the geometry kernel that MoI uses for a lot of NURBS calculations, so it would require a considerable amount of specialized development to even try it.

In the future I do want to work on a type of surfacing method called an "n-sided patch" which is a surface fitting technique that has a few similar elements to it though.
