Problem with invalid mesh

Hi everyone; i have this big problem with this mesh in Grasshopper, which is a ground model created from several contour lines. I can’t bake it bacause it’s an invalid mesh, but I don’t know why. Can someone help me??

Hi Davide
Your pt parameter has duplicate points

what I have to do? If I delete it the mesh disappears.

Delete duplicate points.,such as: Cull DuplicatesQQ%E6%88%AA%E5%9B%BE20190214224959

Now i get this, it doesn’t work. What I have to do?

Your output geometries from Explode’s “s” output are not points. They are curve segments from your curves. Use “v”(Vertices) output instead.
And make sure to “Flatten” your Point(Pt)parameter.
