Orca3D Offset Table Now Available as a Separate, Free Plug-in

The offset table function in Orca3D was developed as a separate plug-in, and it required that Orca3D be installed in order to run properly. Now it is capable of running entirely without Orca3D, and is available as a free download. If you own Orca3D, you do not need to download the plug-in; it's already installed on your system.

If you don't own Orca3D, but would like to be able to create offset tables that open in Excel, download the Orca3DOffsetTable.rhp plug-in. Start Rhino, then drag and drop the rhp file onto the Rhino window to load it (or user pluginmanager). Type the command OrcaOffsetTable, and follow the prompts. Note that in the absence of Orca3D, it assumes that X is the longitudinal direction, Y is transverse, and Z is vertical. Curves that lie in a constant X plane are treated as stations, those in a constant Y plane are buttocks, and waterlines lie in constant Z plane.

RhinoMarine to Orca3D Translator

If you have previously used RhinoMarine, your models may have data that is specific to RhinoMarine, such as sections, weight/cost items, points of interest, and other settings such as non-length units, fluid type and density, company name, logo file location, and project description. With the cooperation of the RhinoMarine developers, we have created a standalone program to convert this information into a format that is compatible with Orca3D.

The program can convert multiple 3dm files at once, and creates new files as output, so your original files are not changed.

The translator is free; there is a link to download it on the RhinoMarine transition page.

Orca3D Update available; Version 1.1.0

We’re pleased to announce the latest update to Orca3D, which incorporates many of the suggestions and comments that we’ve received from our customers and beta testers. Thank you to all who have given us feedback!

Version 1.1.0 is now posted on our website. This is a free update for licensed users; if you have evaluated but not purchased Orca3D, your 15 day evaluation period may have expired. Instructions to request an extension are given at the end of this message.

A link to download the update is given below. Please read through the following information before you download.

Licensing: You will need to uninstall your existing version of Orca3D through Control Panel > Add/Remove Programs. You will not need to make any changes to your license.

Running in Windows Vista or Windows 7: If this is a new installation on a computer running Windows Vista or Windows 7, after installing Orca3D, you must run Rhino once using the Windows “Run as administrator” option in order to install and start the Orca3D License Service. This is most easily accomplished by right-clicking on the Rhino desktop icon and selecting "Run as administrator." This is only required once; thereafter you may start Rhino in the usual fashion. If you do not perform the steps above, you may receive an Orca3D License Service error. You can then transfer your license from your previous computer (instructions are given in the Orca3D Help file).

Rhino Version: This version requires that you are running Rhino V4, Service Release 6 or later. If you don’t have SR6 or later, please download it here:

What’s New: The update adds new features, improves existing features, and fixes a few bugs. A complete list of the changes is available at
http://www.orca3d.com/download/service_release.htm, and just a few of the highlights are summarized below. Short videos demonstrating some of these features are available at http://www.orca3d.com/support/NewRelease_videos.htm.
  • Custom loading conditions for hydrostatics and stability calculations
  • Full T-Splines compatibility
  • Hull Assistant settings may now be saved to a library
  • Foil Assistant
  • User may now specify the longitudinal, transverse, and vertical coordinate directions
  • Improved management of Weight/Cost items
  • Simplified settings for mesh density for hydrostatic calculations (default mesh is also finer)
  • User-defined list of hydrostatic properties (up to 4) displayed in real-time and Hull Assistant hydrostatics
  • Sailboat Hull Assistant now has separate controls for flare and deadrise
  • Ship Hull Assistant has been vastly improved, allowing much better control of the shape
  • Export of csv file with hydrostatics and stability results; easy to import into CE-Pro
As always, we encourage feedback.

Read this blog, post in the forum, send an email to support@orca3d.com, or call us!

Go to http://www.orca3d.com/download/download.htm to download the update. If you have downloaded in the past, send an email to support@orca3d.com to receive the download link.

Need an extension of your evaluation period?

1. Install this release of Orca3D as described above.

2. Start Rhino; you will see a message stating that Orca3D does not have a valid license, and asking if you'd like to activate or extend your evaluation. Click Yes.

3. The Orca3D License Manager utility will appear (it may be behind Rhino on your desktop). Select "Phone/Email License".

4. Send the Installation ID to support@orca3d.com, with a note requesting an extension of your evaluation period. We will email the Unlocking Key to you. In the meantime, you may continue to use Rhino.

T-Splines: A Technology for Marine Design with Minimal Control Points

T-splines are a very interesting class of surfaces that eliminate some of the shortcomings of NURBS, and they have been implemented in a Rhino plug-in. They look to be very useful for modeling hulls with local features such as skegs, bulbs, and fading chines, and also extremely useful for more complex surfaces such as sculpted superstructures. The next release of Orca3D will fully support T-spline surfaces; real-time sections, hydrostatics, weight & cost properties, etc. all work with a T-spline surface just as they do with a Rhino NURBS surface. You can read more about this interesting technology at http://www.tsplines.com/. Also, a paper was presented at the recent Chesapeake Powerboat Symposium by Matt Sederberg on T-splines, and there is a link to download it on our website.
