Re: Pros and cons of steel sailboats

I have found when one does some of the 3d work, or when an architect does a bit more on the plans than a basic line drawing or two or three, one is able to many times see the project better up front. Some folks have no way to picture things like this in their brains from a 2d paper plan.

Then one can also from a 3d rendering, figure out empty places with in the plan that can be better utilized etc too.

Granted I am coming at this from a landscape plan as I have been a contractor for 30 some years, and do have a design degree. BUT, one can see more from a Architect that does 20-30 pages of plans views etc vs a 1-3 page simple plan as I typically did. Probably because I prefered to be getting my hands dirty in the soil, cutting the concrete wall blocks or pavers, etc to spending my day at a desk drwaing the plans.

Re: Pros and cons of steel sailboats

Cas,

Your dads research boat is more of the look "most" folks that live int he islands have for a commuter boat, but usually in the 18-25' range.

Casio - I was actually an early supporter of Brent's...here and elsewhere. My increasingly biting posts were in direct response to his increasingly insulting posts - toward me and others - as well as the blatant inaccuracies in those posts. It always starts somewhere, dude.

I've never been one to just be diplomatic while some dude goes off the rails. Brent goes off the rails...very aggressively.

Re: Pros and cons of steel sailboats

I think many boats have an 'awkward' angle of view.. ie some aspect that looks off, an angle or a line that doesn't please the eye, but move up/down/over a few feet and it's gone. (with our boat it's from dead astern)

The ability to render in 3D before the finalized build plans must make it possible to recognize and perhaps address such an issue before its too late.

That's what I thought.
I've been lost at sea on one of Bob's boats for years....

Glad to see you are surviving the ordeal of owning one of my boats.

A note on 3D renderings:
Paulo is correct. Most designers have someone working with them who takes care of the 3D work. The 3D work takes shape from my 2D drawings that I produce in the normal design sequence....

But 3D work is not about just producing pretty pictures. We can take our 3D files an send the to a CNC shop where they can carve molds or plugs out of foam full sixe. These
tools" will be used to produce the hull, keel, rudder and deck for the boat down to the last detail. This puts a huge burden on the design today to produce design documents that take the place of many hours of hand lofting on the shop floor in order to produce full size patterns and templates for the boat. But it also unsures that a good designer today can exersize far more control over the finished product.
....
Bob, I did not said that NA or Architects, for that matter don't work in 3D programs and that those are not useful even if it is possible to get very good work working only in 2D if the one doing that has a capacity to see in the brain those designs in 3D, a kind of a lost science for new Architects that have been trained working directly in 3D. I think you call that : having a good eye

I was talking about nice renderings and for the ones that don't know much about CAD, it is the designs with the water, colors, land, kind of photorealistic images.

Architects that work in 3D use that kind of wire frames you are talking about and if needed, just to get a better feeling they use a very simple rendering to give a better idea of the shapes. Of course you know this, I am just trying to make it clear to all.

What I was saying is that those nice photo-realistic effects (with a landscape) are normally not made by architects but by specialists and serve mainly to have a feedback from the client or to promote the work, not for design purposes.

Regards

Paulo

Re: Pros and cons of steel sailboats

Bob,

Those are some beautiful designs, but may I make a suggestion?

You were talking about casting some of the fittings on the boat by printing 3d molds. I would really recommend against this. Casting is great where strength and porosity aren't concerns, but in structural applications it is a little questionable.

When I was working for a titanium fabrication company we did a lot of custom work with 3d printed molds, but instead of casting we used a process called sintering. It is similar to casting in that a mold is made then material is poured in, but unlike casting it uses powdered metal which is then heated and held under high pressure. The heat/pressure causes the powder to fuse into a solid mass, but without the voids typical of a cast part.

Basically you get the formability of a cast part with the strength of a machined part. Once you make the decision to make custom parts, the cost between the two is pretty minimal. Sintered parts are more expensive, but not terribly so.
