Hull Modeling using parametric planar surface

You can use a method to generate a hull shape by creating a parametric planar surface and then manipulating the control points to achieve the desired hull form. This approach can simplify the initial hull design process. Here's a step-by-step guide to creating a hull using this method:

1. Define Hull Parameters:
Begin by defining the key parameters of your hull, such as length, beam, draft, and other relevant dimensions. These parameters will be used to control the shape of your planar surface.

2. Create a Parametric Planar Surface:
In your 3D modeling software, start by creating a planar surface (often a rectangular or polygonal shape).
Utilize parametric features or constraints to link the dimensions of the planar surface to your defined parameters. This will make the planar surface adjustable based on your design parameters.

3. Transform the Planar Surface into Hull Shape:
Begin by positioning the planar surface in the 3D space to align with the desired longitudinal and transverse profiles of your hull.
Use control points or other modeling tools to deform the planar surface, pushing and pulling its vertices to create the initial shape of the hull. This is where you start shaping it according to the specific design requirements and hydrodynamic considerations.

4. Perform Fairing:
After transforming the planar surface into a basic hull shape, you can perform fairing to refine the hull's curves and surfaces.
Fairing involves adjusting the control points or curves to smooth out any irregularities and create a more hydrodynamically efficient shape.

This approach allows you to create a parametric hull model by starting with a planar surface and then manipulating its control points to gradually transform it into the desired hull shape. It can be a more flexible and efficient way to explore various hull designs while maintaining control over key design parameters.
