  1. Greetings, With any good 2D or 3D software there are offset features to move a line one way or another. So, with a couple of clicks you can move the spline the exact thickness of your planking. Generally, I decide how many layers of planking will be used and I estimate 30% of each layer will be sanded off when faring a model. This gives me my offset dimension. Actually, very few of the models I make are for museums. Most are for racing sailboats and the dimensions need to be quite accurate to conform with class rules. Generally, also, the lines for these models are quite spartan and one has to be creative to get a nice shape. With about 45 years of experience racing sailboats I have a good eye for what will be fast. It's all good fun! Regards, Rick
  2. Hello Moxis, I think there is another way to look at this problem, which expands on the post above, that will be much easier for you and more accurate. From your .pdf scan, you can take PRT SC of the various views you have and simply insert these in your favorite 2D or 3D program. You can then set the dimensions you want for the part and use the spline features to simply trace out the lines. This will give you much better accuracy than any scanning of the lines themselves. You do not count on the dubious algorithms of the scanning programs; you make your own decisions. Also, remember the originals are based on the outside lines of a ship and don't compensate for an offset that you will need since you are making the bulkheads and then planking over those. You really need to plan for that or your end product will be bigger than the scale you are considering. Plus, you will need to design a keel into the structure. The lines you have end in the original keel width. One way or another you need to cut a new keel into the bulkheads while keeping in mind the offset for the planking as well as the thickness of the wood you will use. Having done close to a hundred of these projects, I can tell you it's easier to forget about scanning technology and just go for it on your own. FANCY IMPROVEMENT: If you want to go crazy with these projects, you can start with 3D software and use surfacing techniques to increase the number of bulkheads. You simply make up the few bulkheads that are included in your lines and then simply loft a surface between the bulkheads. From there you can easily cut the surface and create intermediate bulkheads. For the sake of keeping things square, you can create waterline parts that run all the way along your ship, setting absolutely everything square. This helps a lot if you are making a really big model. Have fun! Rick
  3. Ahh, OK, I see. Indeed, there are two versions of the Spline tool in Solidworks (your spelling is excellent, by the way) for 2D drawing, and one of them probably has the algorithm you noted above. However, I would just not worry about that. Since I am an older fellow, I do remember some interesting algorithms from my days in Electrical Engineering in the '80s, when Computer Engineering was the new kid on the block. Yes, I actually do know how Google finds things. I would say forget about all that. Just use whatever feature kind-of works and practice, practice, practice, until you beat it into submission. The power of current computers is so far above anything we actually see that thinking about how it is working will just slow you down. You should look at learning one of the CAD programs more like playing a musical instrument than learning a computer program. As with music, expect it to take 10,000 hours of conscious practice to learn. And I say this as an EE who spent years really tinkering with algorithms and programming. They are quite useless to me now. Now, I need to create content; get that creativity out from where it's been stifled for the last forty years. Regards, Rick
  4. Hi, OK, as a professional user of Solidworks, and a daily user of splines, with all their features, what is a Bezier?
  5. Greetings. To those who have been waiting breathlessly for me to get back to working on this model, I wanted to let you know that I have a new pair of glasses on the way. Perhaps I will be able to see the thing. In the meantime, I am currently working on a 1/10 scale stagecoach kit from Amati. Since it has nothing to do with ships, I won't be posting it here but it sure is a nice kit. Cheers, Rick
  6. As a daily user of Solidworks, I would like to encourage you to go back and give the splines a second chance. It takes a while to figure out how they work but, once you get a handle on them, you will be much happier than using arcs. Rick
  7. Ha. Well, you did mention "plastic airplanes" in your post. I thought you had actually gone that far. I'm sure I'll be back at my Pickle eventually but it is kind of nice to see things advance easily. Also, I really think my eyes are getting worse. The large scales are fun to deal with and my hands tell me that the larger surfaces are clean and smooth. R
  8. Hi Spyglass, Have patience. On the other, my Pickle has not moved in a couple of years and I did, indeed, switch to "non-thinking" models for a while. I built a wonderful four-stroke engine, easily replacing plastic bits with steel. It was great fun and not frustrating in the least. I am now working on a 1/4 scale motorcycle kit. Again, there is little thinking and it's moving along slowly but surely. Don't throw out Pickle just yet but do take a break with a couple of $25 models. And get better. Best Regards, Rick
  9. Wow, what a nice model. Well done! Happy New Year. Rick
  10. Hi Don, It's nice to see this build moving along. Sorry I've been away from "real" modelling for a while now. I'm heavily into 3D building these days, specifically designing some parts for a "major manufacturer" for a new kit they're building. With my eyesight not very good, I have a great time with 3D building as I can zoom in as much as I like. I'll be continuing to follow this build as you move along. ...and, yes, I will eventually get through the Pickle model... Cheers, Rick

    Pocher 1/8 Scale 1932 Rolls Royce - by Moonbug

    I've built more than twenty of these puppies over the years and still enjoy building them. My favorite, and the one that rates "OK to have in the dining room" is the Fiat.
  12. This is a masterpiece. C'est un chef-d'oeuvre. Merci.

    3D-printing for modellers?

    Hi, Are you using your own printer or just Shapeways? I want to get my own and I've narrowed the search to the Formlabs 2. It seems like the right technology for organic surfaces like ships' decorations. I guess my question should have been Z-brush, Mudbox, or Maya? I already have software for manufactured items. I'm looking for software for carved and sculpted items now. Thanks, Rick

    3D-printing for modellers?

    This topic is going to be at the top of everyone's list soon. For those people who are already making their own parts, what is your favorite software? I am considering downloading Z-Brush, as it looks like it can do the organic stuff for figureheads, etc, but there may be others. Thanks. Rick

    The future of ship modelling ?

    The future of ship modelling is what I call the "Virtual Factory". I just noticed someone starting a new Euromodel Royal William kit. I thought to myself, "How many of these large kits actually get finished?" In fact, one has to wonder what percentage of models actually get beyond the hull stage. My Pickle is a perfect example. The hull is almost completed and I'm looking at the rigging as an insurmountable task. My Pocher models sure seem simple compared to that. I think businesses should think in terms of selling parts of kits, instead of whole kits. A company could focus on making absolutely perfect frame sets. Another company could focus on making planking sets, another on decorations, another on blocks, and so on. Obviously one company could do everything but imagine how much cheaper, and better, a kit could be if each expert could be allowed to improve his part with little regard to the others in the chain. Imagine if someone decided to remake all the pathetic hand-made frames that exist in some current kits, for example, and make them in good laser-cut replacements. That would be such a help to the manufacturers and model-builders. Imagine, also, if someone went to the trouble of redesigning all the decorations on certain period ships, and using laser-sintering additive manufacturing to build the decorations. People need to get together and help each other out this way. Without this kind of thinking, the industry is going to disappear sooner rather than later. Complete kits are simply too costly to develop. My two cents'.
