Intuitively, if looking at a surface as a plane. I assumed: u == x (horizontal) v == y (vertical) w == z (normal)
However when using:
>>>print(rs.SurfacePointCount(objID)) [(V,U)]
That seems counter intuitive. Why does the index increase along V direction???
Hello - U and V and X and Y are not in any way related in 3d - just by chance, so to speak, sometimes. But, I don’t understand the question - indices are counted in U rows is that what you mean? - I suppose it is just a convention… dunno really.

Yes, I know.
I don’t know how to explain it. I assume the matrix of points: [[u0,v0,w0], [u0,v1,w1],… [u1,v1,w1],…, [u2,v2,w2],…]
so if the list of control points indices is inx = [0,1,2,3,4,5,6,7,8,9]
I expect inx[2] to have u = 2, v=0 instead it has v=2 and u = 0.
Hell, when I tried to explained what I mean to you I figured out why is it the way it is.
