Create smooth patch surface from points

[Lim_Ker_Yu]

Trying to create a smooth surface from a set of points, but can only get to this point (with a little crude culling of points as well; is there a more efficient way?) as attached. How can I make my workflow more efficient and properly generate the smooth surface I need?

I think the second round of culling the points at the top end of the curves might not be needed as well?

How can I make my workflow more efficient

Just because you asked, the patch can be sped up quite a bit with a simple workaround (I noticed your sections and ‘rail’ don’t intersect consistently, so curve | curve proximity helps:

Thank you so much!
