Generating plywood panels from hull sections
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? |
Generating plywood panels from hull sections
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 ;)) |

From my limited experience with the program you could put in the offsets for the whole hull or for one section at a time. |

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. http://groups.yahoo.com/group/Cyber-Boat/ P.C. http://groups.yahoo.com/group/Cyber-Boat/ |

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. |

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. 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. 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... 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 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. |

" 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 ???? |

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. 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. 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. 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. |

--It was this ****ing contest mentality that made me stop
reading rec.boats.building. Seems to me the bottom line is this cyber-boat crap is inadequate to the task of designing anything other than a limited variety of hull types. For those who are heading down other roads there *must* be some other software packages available. Assuming you don't want free/limited but don't want to pay a couple of grand either, what *is* available? --As for me I've decided to do it the "old fashioned" way; i.e. make a model, do some tank tests and make sure it "feels" right B4 scaling up. -- "Steamboat Ed" Haas : Nihil curo de ista tua Hacking the Trailing Edge! : stulta superstitione... http://www.nmpproducts.com/intro.htm ---Decks a-wash in a sea of words--- |

Hi
"--It was this ****ing contest mentality that made me stop reading rec.boats.building. Seems to me the bottom line is this cyber-boat crap is inadequate to the task of designing anything other than a limited variety of hull types" No you are wrong --- it was those crap flatbottom fanatics that would not allow things like Cyber-Boat ; if they hadn't won all the Cyber-Boat software would have been avaible and the most beautifull amature boats could have been build but no. Beside The cyber-Boat concept let you design just any shape you want, the ones quite a lot btw. at download can even just be scaled up or down if you know just a tiny bit about CAD, --- No What Cyber-Boat could have brought you, was exactly what you expect computers to bring, and the new framework system acturly could have build any Elegant Bolger Elefant way easier --- and belive it 4 times strionger. No the Cyber-Boat thing was just another "we **** on him and then we say he stink, ---then we steal the bread from his mouth !!!" |
Generating plywood panels from hull sections
The Cyber-Boat guy was just a happy idealist who wanted to share nome
nice designs and the plans to build them --- such like this Cyber-Boat; http://home20.inet.tele.dk/h-3d/Lofot-1.jpg But na no one shall think he is anyone right ; first we **** on him then we say he stink then we steal the bread from his mouth , how great "we" are"??? Sadass usenet fanatics poison belly. |
Generating plywood panels from hull sections
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.. |

Hi
Brian you are welcome to email me . I will ansver your call as I see you mean this serious. P.C. |
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 ;)) |

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? You can do it using Hullform 8 or 9, plate enanced version. You can start creating one hull with the correct section and chine numbers, afther that you can edit the section (edit sections, then text edit) entering the new numbers... You can also use free!ship http://www.freeship.org/ that can make the same thing in a similar way. I speak about free software because I am a non professional, then I use only free or demo software... Paolo |
