Since you are looping through each primitive inside the foreach I don't see why you need a separate ID attribute.
For the randomness you could just use the iteration number: rand(stamp(“..”,“FORVALUE”,0)).

Nurbs patches are square by nature. Trying to fit a surface between 6 edges (3 are the circles, the other 3 their connections to each other) requires more careful planning on how to build them. I don't know how Rhino solves this but you should try to take a look at the wireframe to see how the patches flow.
To still create this effect on a more conceptual level, you should create 1 patch between 2 different curves (or 4 when you need more control, the patch will still be square) and then use some kind of trim to carve out the desired shape. When you have this reference surface you can build new curves on top of it to create patches with a proper topology.

Thanks for your response.
I do not have any experience with CHOPS so I have a few questions regarding your solution.
- Do you apply a cluster before the point SOP or was that just a different solution?
- What is the output of the chop nodes called? In the expression chop I need to make the output of the slope absolute but how would the expression for that look like?
- Sort of related to the previous question, when importing the values to the channelSOP how would that look like, and what does the cluster here mean?
4. The partition node only gives me the option to group by color or alpha, not atribute. What am I missing here?
Your solution looks like what I need but I'm not fully understanding it yet.

I have projected a curve down on a deformed grid with a ray node and given the points a distance attribute. I grouped the points by expression ($DIST == 0) to give me the non deformed points. I need to seperate each series of points so I can perform other operations on it. How do I get separate groups for the red circles I drew in the attachment?
Thanks in advance.
Thanks in advance.
