Hi Tonino,

Hi Tonino,

There are several ways to do that, some automatic some not. Usually I prefer to recreate the curves manually, because imported DXF curves have too many vertices, and it gives very complicated models. I prefer to model with few vertices, then if needed, complexify automatically with a subsurf modifier. But in either cases, what you would do is more or less this:

  • copy 2 curves above the existing ones (so you still have your original curves below)
  • create 2 lines that join the endpoints of the two copied curves. So you form a closed contour
  • select one point of that contour, then Ctrl+L to select all the others
  • Alt+F to fill the contour
  • do the same with every 2 curves, then put everything back into position, then Mesh -> Remove doubles

Hope it helps!
