Hi Boatstalker, no I'm sorry in MoI there is no easy way to take just a big bunch of curves like that and produce the model from it.

I can imagine that some software focused on marine architecture might be able to do something with that, but it would require a pretty specialized curve analysis and surface fitting type mechanism which MoI does not have.

To create this in MoI you would need to have more regularly shaped stations (without protrusions, you would add those later after building the base surface) to go through.

You can also divide up these curves into smaller pieces by using Edit / Trim to cut them with each other and then focus on surfacing each small area. It will be hard to make the final result totally smooth though, you will tend to have creases between each of the small patches.

In areas where the gridding is pretty regular you can also use Network surface to fill that in, like this:


But that needs a clear 2D intersection between the curves, you can't have pieces that don't cross all the other ones for Network, so it won't work to do everything all at once, just sections that have a proper layout.

Network will automatically trim off the excess parts of curves that hang off the ends, so you can actually use it to fill in several strips of this hull like this:



You can repeat that to fill in all the areas that have 4-sided boundaries pretty quickly. But then it will take a lot more time to work on the areas that don't have just 4 sides to them.
