As noted here, there are some guidelines in terms of how to get help efficiently. How to get help on the Dynamo forums
Two of your posts in a row came across as “do my work for me” (see #7) rather than “help me learn”.
In the topic of 'help me learn", there is Python which Alien posted a link to above. From there you will have lines. Those lines can be used to build a TSpline surface using the TSplineSurface.BuildPipes node. There are 13 inputs into that node and only one of them is clear from what you have (the curves list).
Many of us provide full solutions when we have time. Sadly we all have our own deadlines and workload so it’s on the individually to build up the base solution. Short of what you got from chat GPT I haven’t seen any of that. While I am able to spare enough time to say “you can get around the issue you noted above by outputting lines and using this tool you might not have known about” I can’t build a solution for you today.
