Gianluca,
See this Tutorial, a method using using SketchUp only:
http://forums.sketchucation.com/viewtopic.php?f=18&t=9652
........
This Tutorial uses the SoapSkinBubble Ruby Script (Excellent) but you could also use:
TIGs Extrude Tools or
Fredo's Curviloft Tool (currently in development)
Both are also excellent
.........
Hope this helps

Thanks Howard Leslie!
