> It's actually not "insanely complicated"

Hi, your first link talks about NURBS curves, not NURBS surfaces. Cutting a surface in half is significantly more complicated than cutting a curve in half.

And your second link is to a commercial result, an entire book. Presumably because the topic is complicated enough that people are willing to pay $69 to $78 to understand the challenge well enough.

If your DDG search for "splitting a NURBS surface in half" are successful, I'd love to see the results.

No, it's actually the Exact same thing. Just applied independently to each of the curves in one direction.

But none of that is really important. 15 years ago it would be trivial to learn how to do it with a Google search. Today not so.

Also, a book result is still better for me than the commercial tool links which contain no math or theory what so ever.

I can easily imagine situations where I would not be happy with that result.

If that works for you, that's great.

Searching Google for "NURBS Book", "NURBS Course", "NURBS filetype:pdf" all work great for me.

At a guess, most of the people who use Google are using tools, not making them. Yes, Google favors results that make the majority happy. I see that as a feature. If I'm in the minority, yes, I do need to become a more sophisticated searcher.
