At least when it comes to boat hulls, the term used is "lofting"... There are You tube videos on doing it with Inventor and Solidworks. http://www.youtube.com/watch?v=6ZD-As77jhA I think that Violin tops are very much like boat hulls in this respect. There was (or is?) quite a nice violin shop at the park in historic Williamsburg, VA.
