Hello everyone, I’m trying to create a surface from points but it keeps showing error messages. First, it was due to the null values from my list, but I’ve already solved this. However, it compromises the U value, which now is different from the previous list. Do anyone know how to solve it? I’m sending the file below. Thanks!!

Surface from Points expects an orderly grid of points. That’s why it also wants an explicit U count, so it knows how to order them.
It looks like you’re generating your points from a trimmed surface though. If you untrim the source surface, you will get the full grid of points. Process those points, make the new surface and then copy the source trim to the new surface.
If the points really are just floating in space, then a Patch will work, but it won’t pick up the boundary lines
Hi, thanks for your response. Could you please explain the step-by-step with the components? I’m not so experienced, sorry 
The main issue I saw was that your SrfGrid (Surface From Points) input needed to be flattened. I also used Untrim as @Tom_Newsom suggested, then projected the boundary curve onto the SrfGrid output and used it to split that surface.
it worked, thank you so much!!
