Create surfaces among a set of points

I have a lot of points and lines and I’m trying to turn the this array of points and lines into a sold. To do so, I want to select these points and lines creating surfaces between every set of 3 points. any ideas?

Well, if you have just points, you could run MeshPatch on the points to make a mesh. That will just triangulate your points, which is how I read your above request.

Then if you need surfaces as you say, you can run MeshToNurb on the mesh you just created. Before you do this however, make sure you really need surfaces in this case, as it’s not all that useful for the most part.
