New WIP Release (1.4 2017-09-15)

We’re pleased to announce the release of a new Work-in-Progress (WIP) version of Orca3D (1.4 WIP 2017-09-15).

Please note that this release no longer supports Rhinoceros version 4. This and future Orca3D WIP releases require Rhinoceros version 5.

Enhanced Features:

  • Modified Orca3D Simerics Marine Simulation meshing options to allow the user to choose “coarse”, “normal”, or “fine” Simerics meshing.
  • Extended the Orca3D Simerics Marine Simulation command so that keyboard input is supported during interactive definition of propeller geometry.

 Bug Fixes:

  • Fixed a bug in the Orca3D Simerics Marine Simulation analysis command related to defining custom propeller Kt/Kq values.
  • Fixed a bug in the display of Orca3D Simerics Marine Simulation face attributes which caused it to be very slow for large meshes.
  • Modified network installation to target “All Users”


As a WIP, there will certainly be feature additions, changes, or removals before the final release, but this is your chance to give us feedback and suggestions. A few important notes to be aware of:

  • This version of the 1.4 WIP will function only with Rhino 5, and not with Rhino 4. You should have Service Release 12 or later.
  • Only one version of Orca3D may be installed at a time. Therefore, you must uninstall Orca3D from your computer before installing this WIP.
  • No change to your License is required. The new version of Orca3D will find your existing License.
  • Portions of the Help file may not be entirely up to date.

If you have questions as you install and use the new release, remember that you can:

  • send an email to
  • read through the Help file which is available from the Orca3D menu in Rhino, and on our web site here
