Fill Spline based curves efficently As you can see on the image below, I got a lot of vertices after converting the splines to a mesh. The splines a drawn manualy from an old map.

I already started with the filling process. Selecting two edges and fill them with Fwas not a solution, since it causes weird looking artifacts.So my second attempt is to select &quot;nearest&quot; vertices manualy and fill a edge between. This seems a bit tedious and a lot of work.
Does anybody have a good approach to this?
I have a silly Idea in mind: Using a clothing simulation to fall down on my splines and use the fianl result as my shape. Does this sounds like a good Idea?
You can select 2 vertices and create an edge as shown on your screenshot.
Then active edge selection mode (2), and spam F which creates faces until the end of the spline is reached. Select the whole spline by pressing L (Select Linked), then remove all faces (X, Only Faces)
