How to convert a 3D curve to a surface
As the title suggests, I need to turn a curve into a surface. It needs to be a solid object, but I'm unsure in which order to do things. I've read plenty of other questions in the forum that may be describing a similar problem, but couldn't find a solution.
This is the curve that I have, apologies if it's not very clear. Ultimately I wish to turn the following into a solid object:
But nothing seems to be working. I tried the, 'Surfaces from Edges' function, but I can't get that to work at all. Any help would be appreciated, thank you.
P.S. Attached is the co-ordinates file too.
