Orca3D Update Available: Version 1.0.14

A new version of Orca3D, Version 1.0.14, has now been posted to our website. Please visit www.orca3d.com/download/download.htm. This is a free update for licensed users.

This new version adds features, improves existing features, and fixes a few bugs, most notably issues with European keyboard settings. These are summarized below; as always, we encourage feedback. Please visit the forum at www.orca3d.com/forum, or send an email to support@orca3d.com.

Release 1.0.14 (November 7, 2008)

New Features:

· OrcaInsertChine: A new command was added to allow a user to insert a chine (i.e. slope discontinuity) into a surface along an iso-parameter. The command allows the user to choose the parametric direction, u or v.

Enhanced Features:
· OrcaAssignWeightCost: The form for assigning weight/cost to a Rhino geometry object has been modified to allow the user to create new materials by selecting “Add New Material(s)…” from the dropdown list.

· OrcaAssignWeightCost: The command now allows selection of more than one object at a time for assigning weight/cost properties. A “Clear” button was added to the form for assigning weight/cost properties to allow a user to remove weight/cost properties from selected objects.

· OrcaReportWeightAndCost: Added a progress bar during weight/cost report generation since calculations can be time consuming.

· OrcaCreatePlaningHull: The Planing Hull Assistant has been modified so that the resulting hull surface is degree 3 in both parametric directions. It had been degree 2 in one direction.

· OrcaPlaningAnalysis, OrcaHoltropAnalysis: The resistance analysis commands have been modified to allow the user to export the calculation to HydroComp NavCad and SwiftCraft files.

· OrcaWrapCorner: Added a check to see if the selected surface is trimmed. If so the user is notified that the command will remove trimming information and given the option to proceed or quit.

· OrcaHydrostatics: The OrcaHydrostatics command is now scriptable.

Bug Fixes:

· Internationalization: Made numerous changes to facilitate using Orca3D with international keyboard settings. In order to be consistent with Rhino, Orca3D requires all input using “.” as the decimal separator and “,” as the list separator.

· Hydrostatics: Fixed a unit conversion error in output of righting moment in lb-ft units.

· OrcaCreateLinesDrawing: Fixed a bug in display of block and prismatic coefficients when length and volume units are not consistent. Fixed a bug in display of wetted surface area value.

· OrcaReportWeightAndCost: Fixed a bug in which cost item output was sometimes denoted as having been set directly when it was computed from the associated geometry properties.

Orca3D Discounts during November

The response to the initial release of the Orca3D marine plug-in for Rhino has been fantastic. If you haven’t already taken advantage of the competitive upgrade pricing that we’re offering, now is the time to act. Through the end of November, we are offering a discount of up to 50% to current users of specific competing software.

For more information:

For technical questions:

Remember, the discount will not be available after November 30th, so don’t wait; purchase now.

Design Hydrostatics: What is the Design Condition for?

Simply put, Design Hydrostatics is a subset of the complete Hydrostatics & Stability calculation. The idea is to make it possible to compute hydrostatics with a single button click.

Without Design Hydrostatics, the usual steps to compute hydrostatics are:

1. Select the surface(s) and/or mesh(es) to be included in the calculations
2. Start the Orca3D Hydrostatics & Stability command (Orca3D->Stability->Compute Hydrostatics & Stability)
3. Define the flotation condition (weight/cg or flotation plane, etc.)
4. Set the options (Mirror about Centerplane, etc.)
5. Click Calculate

While this gives you a lot of flexibility and options, many times while you're shaping the hull you just want the hydrostatics at a particular flotation plane or weight/cg, and you don't want to have go through each of these steps every time. The Design Hydrostatics allows you to define a special condition (the "Design Condition") once, and then while you're working with the hull you only need to click the Compute Design Hydrostatics icon to get hydrostatics computed in that condition.

To define the Design Condition, go to Orca3D->Stability->Define Design Condition. Select the surface(s) and/or mesh(es) to be included, define the flotation plane, and check any options (such as Mirror about Centerplane). The Design Condition is now defined, and to get hydrostatics quickly just click on the Compute Design Hydrostatics button.

Keep in mind that if you delete one of the surfaces or meshes that were included in your Design Condition, you will need to redefine the Design Condition. Also, the surfaces or meshes that you select for a standard Hydrostatics & Stability calculation will now become the surfaces and meshes for the Design Condition, unless you redefine it.
