Anyone for Ship/Boat Design?

[Fredo]

Hi All!
And let us have a Good 2018!!!

Trying to use the ship WB did not lead me to any result, unfortunately. And searching the Forum did not add much ...

But years ago I did program an Application for Ship/Boat Hull design. It is written in Microsoft Visual Basic 4, thus most probably it will have to be translated to some more practical programming language.

It is fully based on NURBS, with the detail that you can shape your hull by pulling on Wire Cage Nodes or on corresponding Surface Nodes.

To start a new vessel it requests overall dimensions and number of longitudinal nodes. It automatically builds an initial model with 3 longitudinal splines, and the requested transversal ones. But new nodes, longitudinal or transversal, can be inserted at will.

For fairing purposes it displays the typical Curvature Vector along the selected Spline (longitudinal or transversal.

The calculation module is a bit primitive: only Displacement and Center of Bouyancy are calculated.

If you think that this could be useful for the FC - Ship Design WB, just contact me and I´ll send all the modules of this project for evaluation. And, of course, I would stand by as far as possible to help with the implementation. I WILL use it if it becomes available!

Copyright is "CC by-nc", so there will be no problems for FC to use it as is or modified.

Any interest will be appreciated!

Greetings,
Fredo Vollmer

Hi Fredo, we had contact via PM and it is no problem to show your private contact data in a PM. But you better remove it from the public post, due to spammers watching the forum, you can edit the existing post.
As I told you, the following members might be interested, among others.

Hi,
I have a strong interest in all that is around nurbs curves and surfaces.
But I don't have enough free time, nor enough knowledge to make a ship WB.
But if someone starts such a project, I will be happy to help if I can.

this is already great to do ship design with it, I wish I had time my self. sounds interesting.

..there are also trials to test shipshulls in a CFD-environment under FreeCAD.

A serious constructionWB for aero- and hydrodynamic bodyshapes would be appreciated
and have some followers.

Boat design is a strange thing that freecad has support for since its a CAD software and boats software are probably very specialized.

Free Software allows you to create copyrighted products, because... it's free.

That freedom ends if you modify it and distribute it, some licenses (GPL for example) doesn't allow you to distribute it if you don't provide the sourcecode and the same license.

About this workbench, I miss a tutorial because I am very lost, I have never done something.

Hi,
I do like improve my skill in this workbench but need some help. event ought here is an example model that has a maximum deviation tessellation of 0.01%

Have you tried looking in the wiki?
