I have a set of 20 hull sections that I would like to input into a
design program, then generate panels for S&G construction. Any
suggestions for software that will allow me to do that?

Sorry I have no suggestion but I tell you how I solved that problem 15
years ago ; I wrote my own software. See most CAD can do polygon
meshes but AutoCAD only offer a limited way -- rulesurf ,edgesurf are
very limited and will not produce a complex shape but that is not the
real problem, the real problem is , what to use it for .
If you want this it must be to be able to unfold the panels from the 3
D model right ?
Then Rhino maby can solve your problem have you tried that ?
3DMax offer a way to pick one defination line after the other just like
you expect, but can that be used for anything else than rendering the
hull form ?

As I said I wrote my own software that show no limits, I can pick as
many 3D polylines as I want untill the shape are right --- even my
experience are that the fewer lines the more smooth a hull, but I also
had to make my own software to unfold the polygon mesh into panels or
planks, ---- in these years I tried the other software that claim to do
the trick and none of it realy offered something that could be used ;
usealy to rough and way to little faces in the meshes to make anything
but very clumpsy designs. But Rhino shuld be able to unfold meshes made
in Rhino. --- the only one I did not test, except it do not unfold
meshes made in AutoCAD and imported into Rhino.

Hope this was an advise )

www.carlsondesign.com has a free hull program for plywood hulls that will
do that. people who follow this newsgroup have used it. From my limited
experience with the program you could put in the offsets for the whole hull
or for one section at a time.

I've played with Carlson Hulls somewhat and it appears that you can only
input 4 or 5 sections, which isn't nearly enough for my needs. If it can
in fact accept the 20 sections that I need to input, perhaps someone can
clue me in on how it's done.

Do a google on Blue Peter Marine, software from a chap downunder, has a
functional free version and a more capable Pro demo that can unfold and
develop - he calls it plates - but can't save the output in demo I think,
but maybe its worth a try and if it does what you want and maybe it's not
too expensive...

Hi

So we are back again to where it allway's end when questions like this
are made.

Every time the conclution are, that the free download are way to
restricted and acturly produce clumpsy designs. Then everyone fall back
to the brave oldfasion lofting and forget about that there are plenty
examples that this can be done and is in fact simple.
Na no fancy new building methods and 3D-H framework , we stay with 20
year old free download software right ?
You can all go to Cyber-Boat and see how exactly what Brian want, have
produced a number of nice designs ------- yes solved that problem none
of you seem to maneage, still at the same time you see this you can't
cope with the idea that there are a new way to produce the framework ;
as soon as I say that someone who can't even maneage Brians problem
burst out to make sure that no one "think he is something" , the same
old group bullying start with the same question from someone who can't
even solve Brians problem ----- guess why Cyber-Boat unfolding and
design tools are not free download.

Now I'm really confused. I joined the group and did some searching
around and I haven't found links to any Cyber-Boat software. Searching
the web for "Cyber-Boat" produces links to the Yahoo group and a few
other designs, but that's it. Correct me if I'm wrong, but I get the
impression that what's on the group are designs that must be
viewed/modified using AutoCad. Can anyone clear this up for me?

I had the 8S version and I've downloaded the 9S and "plate enhanced"
demo version. It appears that it can do what I want, but it's going to
take some time to figure out how.

No you shuldn't expect Cyber-Boat to offer the free download software,
-- now this been an issue in this group before ,as when you check the
free-download designs and full-scale drawings in the Cyber-Boat groups,
then any amature builder with a small CAD proram ofcaurse would love to
have the simple applications that make this possible.

But due to the group bullying and promoting of specific flatbottom
designs ,vaste material boatsbuilding replacing real boats building and
desktop designers promoting grandfathers designs , Cyber-Boat stopped
at just that point where you all could have profited by it's software
--- software that can do exactly what you asked and _much_ more such as
3D morphing between two 3D designs that then can produce both unfolded
panels and framework ; but no, --- you just check back and see the
bullying and harasment that came as soon as Cyber-Boat treadened the
flatbottom vaste materials "designs" .

Hi

Just to make things clear, Cyber-Boat was taken to a Yahoo site and
_all_ designs was offered as free download ready to post to a print
shop to get full-scale drawings. It was then the plan to also offer the
various software used to produce the designs but a new method and the
sad response in this group made that not happen --- why offer splendid
software to such rigid fools , fools with no respect for an old craft
,fools that obviously was a bunch of sadass usenet fanatics who had
just one pleasure in life ; to harras others and promote their own
"designers" , --- vaste material designers.
