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

"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? "

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.

Oh yea --- but did blue Peter or Carson ???? Build it ????
Well Cyber-Boat was a bunch of acturly _build boats_ and a lot of
hands-on experience happily shared, where this seem to be a fantasy
piece of software with _no_ build experience documentation "did you
build it" suddenly make sense right ????

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.

I was thinnking if you had the sections you could enter them into
Greg Carlson's program one or two at a time just to draw the panels. Never
tried it myself.

I have the old DOS version. I've not figured out the curvature numbers
that will give flat panels (hard chines). I'm sure it's possible. You also
have to go and set the parameters (eg units of measure) before starting to
key in offsets on that version. You have to put in some things like bow
and transom rake before you can put in offsets too. I had offsets from the
Carlson program I wanted to key into the Blue Peter(BP) program. BP starts
with a simple hull and you add lines and sections. It worked best if I
kept inserting sections between exsisting sections until the hull was
filled out, instead of trying to start at bow or stern and key in sections
sequentially. I used BP because it calculated more hydrostatics numbers
than the Carlson program. It was just an exercise in designing a hull. I
didn't build the boat.

How do you expect it to be possible to show the build boats and the
accurate plans , even for lapstrake hulls that is not the useal smooth
surface CAD models of boats, no Cyber-Boat did bring it a step further
these jokers just didn't wanted that, and made usenet their evil
playground.
Still you proberly shuld look closer into the thing I promote instead
of this simple unfolding thing, acturly there are something much more
important than the shivering unfolded panels ,what they acturly are
placed on ,the framework you place any paneling ontop and that is much
more important than the unfolded surfaces ; that is the real challance
,realy unfolding are way overexposed it is nothing and the programming
are trivial , ---- think about it whatever you think you need it for
,it never brought what it promised and why -- becaurse it is as
important to have a structure undreneath the panels othervise they are
impossible to assemble into that shape being unfolded.

Anyway I gave up the proud boatsbuilding crafts ,the inviroment was
simply to poison and there was no bread in bringing beautifull boats
made with at those day's technology ,the homey's rather wanted Elegant
Elefants than nice boats and splendid design ,but true I still have the
software I didn't use for years but as I said, maby you shuld consider
if the computer unfolding realy are the important issue. Whatever you
need it for.
The Cyber-Boat guy don't exist like that anymore I had it with the
plesant gentlemen here and realy it is years since any nice
craftmanship been on display in this group ,if it was it would first
meet the slick guy's then the pretitors --- it proberly be the same guy
with just a fake usenet identity..

Who said anything about "free"? What I asked was for a program that
would allow me to enter sections, fair the shape and create panels.

Frankly, I really don't care about all of that nonsense. I wasn't part
of it (I don't even know when it happened) and I'm not going to get into
it now. I also have no interest in your ranting, as it's not solving my
problem. If there is software available that will do what I need, please
tell me where and how to get it. If not, please don't waste my time
telling me about a product that isn't available.

As far as I can tell, it will only accept a limited number of sections.

The current version allows you to input basic shape parameters (curved
or hard chine, freeboard, etc.) and the number of sections at the
beginning. I'll need to move and modify the sections, but at least it'a
a place to start. I've taken the sections off a skin-on-frame boat I
built, so the design is tested, and I want to duplicate it in
stitch-and-glue.

Thanks Bill. I guess I'll just play with the demo version for a while
and if I can generate the panels I need, I'll buy the full-function version.

Hi

Brian you are welcome to email me . I will ansver your call as I see
you mean this serious.
P.C.
 >> Stay informed about: Generating plywood panels from hull sections 

But Brian please understand, that offcaurse the exact software you ask
; realy would you think it wasn't the idea to share both designs and
old for me old fasion applications , boatsbuilding was over with my
Cyber-Boat experience ,and as it seem ,and even I now mean that silli
unfolding are not the issue ,then offcaurse the software _and_ the
designs I build just to document the method ,shuld realy both be public
avaible. ---- My sad exchouse why I lost the reson to do it ,and
acturly found it irelevant to build further on a dead end building
method ; now I just say that nomatter how exact you cut thin metal
sheet then without something to place the panels on or lock together ,
realy unfolding are quite trivial the real issue is what to put the
unfolded panels on to , -- if you have the framework you could even do
the lofting the old boatsbuilder way on site on a framework that's
nothing.
Guess why I sort of lost the drive even I maneaged to upload all the
most important Cyber-Boat drawings into the Yahoo groups, realy it was
the idea to also publish the applications and, even they are old and
dusty, they seem to do exactly what still is expected , but give me
just one reson why even bother .
I think I once placed all the software on a floppy --- you load a new
AutoCAD menu where the various design tools are listed with a screen
menu. But realy ; why even bother ; if so I shuld publish the Lisp
applications ,the code that make up each application , well why not.

You see the method are difficult and unless there are a planned
structure ,it is a mess nomatter how accurate the sheets are cut, so I
guess I don't "lose" anything, publishing software that was relevant
for me as boatsbuilder 20 years ago )
