# 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!
