Your mesh's points were already very nicely ordered.  Just decompose the mesh and feed its vertices into a surface from points component...then just tell it you have 11 points in the U direction, and you're done!

Thank you both...

Now we are close to the solution...

I have done some tests.

Can you look at the example? The first definition work quite but I don't like that tessellation, I need a smooth surface (like rhino analysis). 

The second one is smooth but have some problems but I can't figure out where... 

The thirst one is rhino analisis (like what I need in GH).

Can you help me? 

Thank

I dont get what the problem is?

The problem is that I can't get a smooth color surface like the one that I can create with rhino analysis curvature tool.

Hi.. 

This is what I get at the end... quite close to what I want... 

I have the last few questions.

How can I remove that kind of tessellation? 

How can I remove the reflection?

Can made a jpg of that directly?

Thank you

Hi 

I have solve some of my problems, but now I have to find curvature on free-form surface.. 

I tried this way (see attachment) but it does't work.. 

Do you have any suggestions?

Thank you
