There is a knitting geometry paper which uses Catmull Rom curves, mathematical optimization, then conversion to Nurbs.

Does Moi do any Catmull Rom Curves?
Are the "obsolete" ?

I've located 200 line javascript programs which do Uniform, Chordal, or Centripetal Catmull Rom 3d curves, so a script might be possible?
Not sure if it is worth spending any time on this?

Moi interp curves, or control point curves can be done instead...
