<p>Hi Chris, </p>
<p>I am also working with a similar issue. I have a list of points (in text format), and i'd like to make a surface with them, ensuring that i can change the z value as needed. I'm looking at your gh file at the moment and I am confused by the image sampler and its role in the script. Basically, I'd just like to do what I've stated above. With this script is it possible to change it so that each point can be assigned different values in the z direction? Seems simple, but…</p>

<p>Sure, it would be easier if you could upload a file you are working with - just because I'm not sure exactly how you are generating your points.</p>
<p></p>
<p>In general it's just list management. You can do this a few different ways (using series + list items, sublists, path mappers...)</p>

<p>Could you please tell me how to make a NURBS curve through each row of a grid of points? or through a list of points?</p>

<p>Chris T has described the solution you are looking for. </p>
<p>Here is a very minor variation on that theme, using the good old image sampler. Attached are the example files with some notes on what is going on. </p>
<p>if you want, you can read through the notes. They are intended to explain a few things, as well as pose a question or two!</p>

You could interpolate a curve through each row of your grid of points and then loft the curves. The surface would then update as the points move.

<p>That worked, but now I have a flat plane. I would like my plane to conform to the grid points as they are set after I moved them. This is why "flattening" does not achieve the final product I'm looking for. I would like the surface to curve... How else can I manipulate the points of a nurbs surface?</p>
<p></p>
<p>thank you! </p>
