Remember when I said, I was busy with a new way of handling a bspline surface, away from the vertex level. Well after developing and testing those features against some STL parent hulls from Freeship, I can conclude it works very well to my expectations. A special AEIS bspline surface feature was created to read special AEIS bspline curves. The hull was created based on AEIS curves created from sections positioned/planned carefully across the STL ship hull. All AEIS curves was created directly from those sectioning process. Each curve consist of 16 control points.A ship hull can be created with just 6 up to 7 AEIS curves.

An AEIS curve can be a master curve or slave curve that depends on 2 other AEIS master curves.

As you might notice, the ship hull can have the following forms:
1. flat region
2. blend region
3. curved region
4. knuckle region with certain distance

Before "tracing" the STL ship hull, one needs to identify the surface characters/form of model then based on that think a strategy on how to implement those AEIS curves.

You can also create a blank new hull with those curves.

They need further fine tunning like adding some modifiers to make working much more easier.

To my knowledge, I never hear or saw those features in Dassault Catia or Siemens NX.
