Nihar, this is a lot of highly involved technical questions and not really much time to get into detail. I suggest you just research as much as possible to understand approaches and make a proposal to the best of your understanding. That said, I’m not sure any of this is answerable without knowing what specific user feature you are aiming for. “NURBS Editing” can mean many many things, you have to define a set of objectives.

It’s not clear to me at all what problem you’re addressing or what NURBS editing operation this relates with. The paper you refer is about trimming a subdivision surface. We already utilize a trimmed NURBS surface boundary representation and evaluate those trims in a variety of ways. > 2.

Normally, I’d say this is exactly what you are supposed to research yourself. But this is a crazy complex topic and even more complex code, so I’ll save you some time. None are provided. Most are desirable. I have a feeling you’re way overthinking algorithmic approaches before even running BRL-CAD. We need very basic editing support. Grab a corner of a box and move it. Grab an edge and move it. Grab some point on a surface and move it. Do any of those without destroying the integrity and continuity of the neighboring edges/surfaces. Not easy. Cheers!
