Orca3D Version 3 is compatible with Rhino 7 and 8.

If you currently use Orca3D Version 1 or 2, [upgrade to Orca3D Version 3](https://orca3d.com/pages/upgrades) to be compatible with Rhino 8.

Orca3D’s packaging has changed in Version 3. In prior versions of Orca3D, you could purchase Level 1 and Level 2, with Level 2 adding to the Level 1 functionality. In Version 3, instead, four modules are available and may be purchased in any combination.

- **Design:** This includes the Hull Design and fairing and Basic Hydrostatics and stability features. It is equivalent to the previous Level 1.
- **Analysis:** This includes the Speed/Power feature, the CFD interface, and the Weight & Cost feature. It is equivalent to the previous Level 2, except that it does not include the Level 1 functionality. The Analysis module may be purchased without the Design module.
- **Advanced Stability:** Includes compartmentation and tank modeling, fluid and solid loads, unlimited load cases, free surface effects, intact and damaged stability with stability criteria evaluation, and tank tables. This is a major new module.
- **Orca3D Marine CFD:** Requires the Analysis module as a prerequisite.
