After installing Orca3D and starting Rhino, a toolbar with two buttons will be shown:

Clicking on either of these buttons will bring up the three standard Orca3D toolbars, either with or without text. While the text versions takes up more space, they can be helpful in learning the icons, especially when you're new to Orca3D.
Orca3D's toolbars are stored in the following directories:
| • | Windows XP: C:\Documents and Settings\All Users\Application Data\DRSC3ATC\Orca3D |
| • | Windows Vista and 7: C:\ProgramData\DRSC3ATC\Orca3D |
You must have write permissions in this directory for your toolbar settings to be maintained.
You can also decide which toolbars to display using Rhino's toolbar layout function (Tools->Toolbar Layout):

The Level 1 toolbars include functions for Hull Design & Fairing and Hydrostatics & Intact Stability, as well as miscellaneous functions such as Orca3D Properties, the Orca3D Tree, and Help.

The Rhino Functions toolbars contain standard Rhino functions that are not exposed on the standard Rhino toolbar layout, but can be very useful in marine design. Each of these functions is covered in the Rhino Help file.
