Rhino meshes for hull design

Hi all

Although this my first post, I’ve been following your discussions for a long, long time. Now I wonder if someone could give some tips.

I’m trying to model a ship’s hull in rhino. At the end I managed to get something, but not as good as it should be.

Next step is processing the hull in a software to get some enclosed volumes. Here comes the problem. Seems like hull patches boundaries are not good enough to form an enclosed volume. Patches were built trying to keep tangency continuity between surface edges.

Some time ago, a person with some experience in these topics, told me about using the mesh tools of rhino, to rebuild meshes limits, and get an smooth and continuous surface afterwards.

Welding meshes, boolean union? I did the try but it seems to be a complex matter. Does some have some help materials?

Thanks in advance

Hope this conversation helps someone else.

Hello - it looks to me like you have a reasonable patch layout - maybe more complex than necessary but workable; the problem I see is that the surfaces themselves are vastly over complex and are not paying attention to one another at all in terms of point distribution and direction. This will make it very hard to get a clean hull, which I would go after before worrying about a closed one.

It might not be a bad idea to look at the level 2 training material on surface topology, and contiunuity -

You are going to want to handle this with a single lofted surface https://www.youtube.com/watch?v=3XkdIsleAqY. Then you’ll need specialized software to generate the ribs and developable surface plating. https://www.youtube.com/watch?v=l1C34Y_QDXY

Thanks for your reply. But if this is a matter of doing some spam, then I’ve to say that FORAN is my shepherd, there’s nothing I lack.

Thank you so much for your reply, Pascal. I really appreciate it. I’ll have a look at the materials, hope this helps me so I can spread the rhino word around.

Best regards,
