Move selected Surface's CV along UV!!

[Lucius Santo]

Hello Everyone,
is the first time i write and i am a beginner in programming! And i apologize for my English
Now, please, i would understand how to move the CV of a existing surface ... and in particular I would understand how to move them along a direction (U or V) so that in a view (so in projection) is aligned to a curve (not only a straight line).
First of all, I can not even figure out how to identify a single point of this surface!

Thank you so much for your professional help!





Thank you so much for your professional help!

Lucius,
here is an example from the helpfile of how to access the controllpoints:
http://www.rhino3d.com/5/ironpython/...facepoints.htm
It is probably easier to recreate a new surface from the points after you modified them instead of trying to move around an existing control point.

If you want to learn more about programming in rhinopython in general I would recommend this pdf:

Many thanks Goswin ! But I thought it was possible to directly manipulate the CV of a surface (each CV callable) ...
But I realized that perhaps it is too difficult for me to try to use some functions ... such as lists without confusion.
And I also tried to read the book but I have to perform the operations that are unfortunately too complex (for me I think). Maybe I'm missing practice to develop routines and is logic ...

Many thanks!!!
But I'll try!

Lucius,
I think you can use Object Grips too to move Controlpoints of a surface around, for example:

Thanks Goswin, I try now, You're a friend!
And then I'll tell you ...

Hi All ^_^,
I tried to build a surface from his CV.

The surface should be simple:
U = 6 CV degree 5
V = 6 CV degree 5

I thought about using the command "AddSrfControlPtGrid."
I provide 36 CV as input but I have several errors, probably mistake the syntax ... Can you help me? Thank you so much!

Here's the listing:
