CATIA for boat design

[signum]

I am trying to work first time with Catia V5 r14 version. I wish to know how can I move the work plane where I need, in Rhino for examples you can change very easy the work plane, rotate it and move it wherever you need. How can I do same thing in Catia ? Should I generate maybe another plane than the original one?

You should be able to offset from your reference plan using reference geometry tools.

I find it very hard working in planes (considering that most parts of a boat are non-planar. I work in world co-ordinates, I find it is easier to plan what I'm doing.

I trust you have a good instruction manual, but if you have access to Rhino, Catia seems a little redundant. Check out the IGES exports from Rhino, one is a Catia format.

Hi Tim.

It seems you have experience with Rhino and Catia too. Why do you consider CATIA redundant ? Rhino is a very good modeler and I like it very much, it's easy working with but I found even here on boat design at the software chapter CATIA is clasified with four stars among the best software for marine design. It's more complex than Rhino.
Can you give me more information from your experience ?
Since I posted my question here I did no progress with Catia cause I hadn't time. I wish but I was busy.
Thanks.

Hi Signum,

If you are using the regular Catia version with no hull design plug ins then I can recommend you to use any hull design software to model your hull and then export to catia to create your hull structure, Catia works in principle similar to other MCAD systems, Solidworks or PTC seems to be so far the one more used, catia is a higher program but not so friendly modeling hulls the same as it is in other MCAD software's, Catia has some plug ins or modules for hull design and even hydrostatics, but if you don't have these modules then try to create your hull in other software like Rhino or Prosurf or Maxsurf there is multiple choices and once you have your model then export to catia, and do the rest there, the same for the superstructure.

And about Catia to be as one of the best software's for marine design if you don't have the modules for that, then IMO is as good as almost any MCAD software, solidworks, PTC, Solid Edge etc...

I wish I can help more with Catia but I think you should try the way I mentioned here, or buy the modules for marine design.


Cheers!

I don't have a lot of first-hand experience with Catia, but I have seen it used, and I know people who use it. Rhino, on the other hand, I'm very familiar with. Generally, if you get down to actually manipulating the surface directly, Rhino, it seems, is very good. Catia seemed more cryptic to get into (and a lot more expensive).

If you are after Hydrostatics systems, myself and Nico are writing routines. My routine takes the NURBS surface definition directly, whereas Nico's requires a raw triangle mesh first. Neither routine is ready for release yet. But (hopefully) will be in the next few months. Both routines can be used with most systems (if you can get the input data out).

Catia's redundency comes from the fact that Rhino (especially version 3) is really an advanced CAD package as well as a solid modeller. The only serious drawback with Rhino (at the moment) is that the 2D draughting tools (Line colours and styles) are rather poor. For this I use a program on another machine.

Although Rhino is a very good modeller for the price , beware that the surface quality that you can achive from Rhino is not very good, dont expect to be able to transfer the surfaces to a CAM application and get good results first time.

[Tim B]

Rhino's Surfaces are accurate, if you're having CAM trouble, that's either from over-simplifying the export of geometry, or the CAM system not importing the geometry well.

The surfaces in Rhino are among the most precise of any free-form modeller- with the right settings, a tolerance of 0.001 mm is possible. With due care in the CAM import, you can easily get a milling file that is closer to the actual surface than the tolerance of the CNC mill itself. It's a matter of being careful with formats and tolerances.

Hello !!
I want to ask ,what is the name of the plugins for the CATIA hydrostatic and hull design?? And to for the which version?
greets

Here is the link of a company that has some tools for catia including basic hydrostatics and surfacing, beyond this there is the shipbuilding solution form catia wich is a PLM for full production but only for the production side (structural, arrangements and management of the project)

I haven't seen a "true" hull modeling (Hull surfacing) package or add on for catia similar to Surfaceworks ("add on" to solidworks).

cheers

What, a standard as in a whole lot of people using it?

CATIA is an excellent CAD system, but I have yet to see any evidence of it being widely adopted by the yachting industry.

[CDC_Catia]

I am not claiming that everyone is using CATIA in the yacht industry, however, CATIA is most definitely becoming a first choice amongst some of the biggest names in the industry, Customers include market leaders such as Beneteau, Jeanneau, Cranchi, Hallberg-Rassy and Elan Marine in the small yacht space. In the large yacht market, shipyards like Heesen Yachts and CMN, while in engineering and design, customers include, Berret-Racoupeau Yacht Design, Vaton Design, LNM, Rivoyre Ingénierie and Humphreys Yacht Design
In the CIMdata press release below it explains what I mean by standard.

Hi Tim,
Rhino 4 has a large set of new drafting tools that you may find useful; line types, line weights, hatches, page layouts, and improved printing.

Thanks,
