Chris Ostlind Previous Member   For what it's worth, I concur with Herron's use of Hulls as his sketch pad for doodling ideas and then porting them to a higher plane of software.
In Freeship I sometimes feel that I can't control the lines of my designs as much as I would like. I hope this makes sense because I would really like to know whether a (cheap) package with such features exists.

When making potentially dangerous or financial decisions, always employ and consult appropriate professionals. I have already built one hull like this and want to design another hull of similar shape but different dimensions. Location: Cathlamet, WA It looks to me like freeship will do this but only if you import coordinates of the sheer, chine and fairbody. Location: Cathlamet, WA I will try to explain what I meant in the previous post. My results from trying to arrive at a developed surface using the SURFACE features of freeship have not been successful. I have found that if I type up a text file as described in the manual that lists the coordinates of the points for the fairbody, chine and sheer at each station from stern to bow it appears that freeship will do just what you are wanting to do.
After you have your text file, start freeship and click on the FILE menu, click on IMPORT, click on CHINES, and then select your text file. There is a dialogue box where you can input where you want the stations, waterlines and buttocks drawn.
Form the (very) limited amount of playing Ive done with it, it looks pretty cool, I especially like the updating SAcuve and basic hydros as you modify the design.

I create surfaces for the new curve set and end up with a very clean, very fair hull that is ready to be analyzed hydrostatically by RhinoMarine. I use Rhino to develp the rest of the structure to complete form as well as render the design for presentation graphics. The images attached are for a solo tripping canoe that was designed and rendered in less than two hours complete with full hydrostatics from two independent, confirmation sources.

Simple still gives you everything you indigence to design a hull trump of completely its FREE.
The panel rib stringer feature is the only structure that matter in ships building, with a honeycomb structure you get exactly the same thing just everywhere and so much stronger than focus on the single frame .
Realy building a boat or a ship isn't that structuraly, to panel a box structure to get the strongest structure compared materials, that case why fiddle and focus on 20 different beams and screws when everything can be cut flat need no bending.
Location: Edinburgh Just found a new program which looks impressive and is totally free! Location: Edinburgh Just checked out the latest version of FreeShip - it now has full hydrostatics, plate development and more!!!
Are there any Alibre users who can pass an opinion on the value of getting the unlimited licence? Another thing about multisurf is if you do buy it, They are based in Maine and do quite a few seminars in the area. Please do not hesitate to ask any question you need and to propose improvements to the program. The second step is to include calculations of ISO 12215-6, longitudinal strength, keel, knuckles, etc..

Location: Spain ISO disregards the resin to be used, probably because it assumes that adds no strength to the assembly. ISO does have in mind, however, and strongly influences the final composition of the panel, molded type and level of evaluation. Location: Philippines The choice of resin can and influence a lot on the resulting laminate strength. I have programmed the LR composite calculations several years ago but with the advances in composites, with a wider choice of fiber and resin combinations, I am making a more versatile program. Not primarily intended for boat use (but can be adopted) for a more precise prediction of ply properties. And I'm again expressing my opinion: I think the ISO simplifies some calculations that make them to detail would be beyond the reach of many of the technicians who seek support for their projects through a regulation officially recognized.
It is just my work covers advanced composite designs and when sales people talks about this and that resin or that extra sophisticated fiber increases strength tremendously, I started to find the answers why.
In conjunction with the standard, this application tool assists scantlings calculation for boats in design categories A ? C up to 12 m and category D boats up to 24 m and for materials GRP, steel and aluminium. An initial study of the scope of application of the software (see tutorials) and the system requirements is recommended prior to working with the spreadsheet.
Location: Spain This program allows you to view a series of videos that describe the first steps with SCT. I can run all of the modules developed by ICOMIA for the ISO 12215-5, except the Module 1, for GRP motor boat calculations. I am in same situation as Ernesto, Windows 7, Office 2010, 64 bits (it has to do with this?). Location: Iowa Best way that I have found is to make sure it is a separate layer to start.

By implementing the very latest technologies for real-time 3D visualisation, it is able to simulate a wide range of mission variables: from changing currents and visibility, to electronics and gear failures.
My biggest concern with using software to design this boat is that the sheets will be somewhat convex due to warping the bottom. If I understand your reply correctly, freeship will convert the hull shape drawing into flat sheet dimensions, but may or may not compensate for the convex sheets. Now I understand that the subdivision surfaces used in Fee!SHIP can only be approximated by NURBS but has anyone successfully been able to get an IGES nurb model out of it, and if so what are the tricks? Hulls has a very simple hydrostatic analysis function, but it really only serves to get you in the ballpark and the data it reveals is not as in-depth as you will find in FreeShip.
Once the panels are nested, the design will be ready to take to a CNC shop for cutting and construction. I didn't give you the file with the interior so I was trying to explain what I had in mind. I noticed that the DWL was very high, and I assumed this was done simply to play with the flowlines.
You will have to fiddle with the draft to return to your proper displacement each time you change the heel angle. Few things can be more than cheering than buiding your own Few thingsm that is take out designing it too. Instead you "press the button, and as it's a CAD model it is easy to calculate a simple assembly framework , each frame just cut sheet metal not 20 different beams stringers, hangers nuts and bolts ,one material cut with a laser or water cutter . So when it comes to panel thickness or reinforcement, or weight, does not take into account the resin. Although the resin hides under the shadow of the fiber, the strain to failure of the resin is relevant to the strain of the fiber. I am attaching a snapshot of what I am working on which solves the limitations of LR, BV, DNV.
So I gather, and this is the only time I thought of myself, that does not account for all the resin and, I gather, it's because no influence on the ultimate strength.
A professional with your experience and knowledge can bring many positive things to my program.

Compared with commercial software the application has to be understood as a basic boatbuilding calculator. And I read the user guide for the 12215 software, and that looks really interesting, I want to use it. Then you need extend the top up so it lands above the waterline (issues with hydrostatics). As lewisboat said the only way to have it as a part of the hull itself is to use the points on the bottom centerline and then create one. Will these software packages compensate for that and still provide correct cutting dimensions for flat sheets? The resultant curves have way too many control points, so I delete about two thirds of them and then fair the curves as closely as possible to their original shape. Freeship has become a truly unique and wonderful addition to the workflow in my shop design environment. The cockpit is self draining so if the cabin entryway is sealed properly it should drain itself if and when you get it back upright. It was only after I read your post that I saw you had posted in the Plyboats thread and had thus probably seen the interior and cockpit layout.
And so, I correct my opinion: ISO probably not worth taking into account the contribution that the resin makes the total resistance. I repeat that this is only my personal opinion, not based on any study, only in reading and understanding (I guess) of ISO 12215. You could import the keel and then create points and lines by lewisboat's method, using the imported keel as a model. Lo que puedes hacer es mirar a la lista de los tipos de archivos y comparar los de freeship con los que puedes importar en rhino.
Nope I don't speak Portuguese, only a (VERY) little Spanish, French and Italian but it is pretty easy to decipher. I have never used any boat design software, so I do not understand the capabilities of any of the software packages.
A reverse chine is kind of hard to explain but it is a long thin (almost flat) section of the bottom sheets at the chine.
But check out multisurf, 4 or 5 years ago, I was drawing hulls with my input in a matter of hours, lost interest for a while but I have the bug again. From there, without deviating an inch from the norm, I wanted to create a tool to carry out the calculation she asks, in a fast and user-friendly way. I use Virtualbox to run windows, so when it gets infected every few minutes, I can throw the VM away and go back to something clean. I mainly appreciate the fact that I can draw through 4 view ports with multiple construction planes with minimal effort.
The reason I ask these questions is that I don't want to spend a bunch of time trying to learn the software, when in my case I may be better off to spend that time building a scale model of the boat and take the flat sheet dimensions from the model. Robert Livingston’s Free kayak design software is worthy for designing strip built modest craft hulls.
I haven't done much with the program yet but the interface looks good and the buttons work so have another shot at it. The only way I have ever been able to do that is to move the centerline of the hull bottom into a keel shape then extrude the edge down, shape it and then either bend the lines back to the CL or extrude back to the CL.
Outboard of each of the bottom sheets is a 6" wide sheet at the chine that is almost flat (angled downward several degrees on the outside edge).
I establish this site http projects freeship I played around with for ampere little turn looks interesting.
This makes the keel out of the hull itself but really messes with laying out panels if you are trying to get it out of ply. This long skinny almost flat reverse chine sheet runs the full length of the chine, about 6" wide at the stern, narrowing down to a point at the bow.
