Hull Design & Fairing
The design of a vessel in Orca3D begins with the hull model. Hull design is a unique combination of artistic expression and engineering analysis, combining to form a creative process to meet the aesthetic and performance requirements of the vessel.
The software that you use to transform the hull from an idea to a 3D computer model should enrich the creative process, with guidance provided by precise and detailed analyses. With Orca3D, you have complete freedom to create any type of hull, beginning with a concept and carrying through to final fairing, while ensuring that the hull meets your target hydrostatic properties.
In Orca3D, the hull is created as a NURBS surface. While Rhino provides many important surface creation and editing tools, Orca3D adds capabilities that are specific to hull design, such as:
- Hull Assistants, for instantly creating hulls according to a range of input dimensional and shape parameters
- Easy definition of the sections to be displayed on your hull surface; stations, buttocks, waterlines, and other planar curves. The user may specify the color of these sections, together with the layers upon which they should be placed.
- Real-time update of the sections as the hull surface is modified
- Real-time update of the hydrostatics as the hull surface is modified
- Control over the shape of the forefoot of the hull, ensuring a curvature-continuous transition from the stem to the bottom
- Easy positioning of the surface’s control vertices, either interactively, or via Orca3D’s vertex control dialog
Any type of hull and hull feature may be modeled. Hulls may be created as a single surface, or when appropriate, multiple surfaces. Tools like blending, trimming, and filleting provide tremendous capability and flexibility.
