Well if you could the surface definition as opposed tot he curves fromthe originating system you could just mesh it and be on your way. You would need to use the curve and build of the new surface definition as it is. I would just make a bunch of 3D sketchs (convert curves to sketch entities so you cna loft he hull as appropriate. Life would be a lot more efficient if "select tangency" was support on these curves. The highl lighting sort of suck as well so hard to just use the curves to make the loft. Good luck but it looks like a bit of work to make it into a sensible number of feature. I would not advise usinghte surface fill and just fill up every patch witha surface. That would lead to a big feature tree. Good luck.
Like Bill, I would not use Fill for most of the surfaces. The Boundary Surface would be the better choice, although sometimes the Loft Surface is preferred. The default for most folks now is Boundary. Fill is very useful when you have an odd shape, such as a triangular patch or a round patch, that is hard to make with the other surfaces.
I Agree with Bill and Jerry, there are no quick ways about this one. (Unless your hull-design program can export iges surfaces and not just the curves.)
Some other tips:
Try to think in "half a hull", which will reduce your building time. Once you have completed the one side, it is an easy matter to use mirror for the other side.
For a start, it seems like the individual curves can be used for loft or boundary surfs. Tested some, and with patience it can be done. Had to use a 3d sketch > convert entities at some places.
I deleted the curves on one side, to make things neater. Seems like you can not box-select several curves, they have to be picked one by one. Tip: Make use of the Enter key to repeat last command, that way you can pick-enter-pick-enter after the initial deletion.
