Rhino插件 船艇设计软件 Orca3D 1.3.0 英文版 32+64位版

Orca3D

Developed and supported by the same team that created another Rhino marine plug-in, Orca3D represents the latest thinking in marine plug-ins for Rhino. Orca3D is a totally new program written using the latest development tools, and comes with first rate technical support. Development is active and on-going, and support and incremental updates are free.

Building on Rhino's powerful 3D modeling capabilities, Orca3D provides marine-specific tools for hull design and fairing, hydrostatics and intact stability, resistance and power prediction, and weight/cost tracking. With the Orca3D plug-in, you can conceptualize, model, and analyze your design in a single environment, without the tedious and error-prone task of transferring your design from one program to another, or the need to learn a new user-interface.

Begin with your own surface model, or instantly create a hull using one of the Hull Assistants. Easily define station, buttock, and waterline locations in your hull, and watch them change in real-time as you modify the hull surface. Three-view lines plans and offset tables can be automatically generated from your model. With the OrcaMove command, control points can easily be placed at exact locations, and sections and hydrostatics update in real-time as you modify the hull surface.

Hydrostatics and stability are computed using the surface mesh, or can be computed for a mesh object. The model need not be entirely sealed, nor perfectly joined. Complete curves of form and righting arm curves can be generated, or specific flotation conditions can be analyzed, by specifying a weight and center of gravity, or a flotation plane height and either LCG or trim angle, and either TCG or heel angle. A complete report, including plots, is generated and may  be printed or exported to Microsoft Excel or Adobe Acrobat. Orca3D will insert a planar surface into your model representing the equilibrium flotation plane, including markers to denote the centers of buoyancy and flotation, or it can transform the model so that the Z=0 plane in Rhino's world coordinates corresponds to the flotation plane. Both of these options make it very easy to visualize the equilibrium condition of your vessel, for example with a given displacement and center of gravity for a loading condition, or at a specific heel angle.

A "Design Condition" can be specified while designing a hull, so that you can compute hydrostatics and stability with a single button click.

Orca3D includes a tree control for viewing Rhino's layers, but also displaying the objects on those layers. This control simplifies the process of managing your model, making it easy to drag and drop an object from one layer to another, and intuitively control which layers are visible.

Orca3D predicts the speed/power characteristics of planing and displacement hulls (Savitsky and Holtrop methods), using the built-in HydroComp drag prediction library.

Weight, center of gravity, and cost properties of your model are easily monitored with Orca3D. A library of stock materials can be created, with weight density (e.g. kg/m^2 for a surface) and cost "density" for materials and labor. As the objects in the model are modified, Orca3D updates the total weight, center of gravity, and cost of your design. Objects that are not modeled are represented with point objects
