Orca3D 3.1.7 For Rhinoceros 7.38-8.26

Orca3D

Orca3D is the premier naval architecture plugin for Rhinoceros (Rhino), seamlessly integrating professional marine design and analysis capabilities into the world’s most versatile 3D modeling environment. Developed by naval architects for naval architects, Orca3D transforms Rhino into a complete naval architecture workstation—enabling designers to create, analyze, and optimize vessel designs without leaving the familiar Rhino interface. Version 3.1.7 extends this capability with full compatibility across Rhino 7.38 through 8.26, ensuring that marine designers can leverage the latest Rhino advancements while maintaining access to Orca3D’s comprehensive toolset. From initial hull form development to final stability calculations, from intact stability to damaged stability analysis, from speed/power predictions to weight tracking, Orca3D delivers the precision and efficiency that professional marine design demands.
