  1. Fusion 360

    I also can't comment on Onshape. However, I have been learning Fusion 360 for the last few months, after using Microstation since it started.The tutorials by Lars and others are excellent, as is the program.
  2. Hi Ben, i am currently learning F 360, crossing over from Bentley microstation. My immediate issues are importing 2D and 3D drawings to F360 from BMS, and creating a hull surface. The results are variable, to say the least. Tutorials are helpful, but if you have any insights I would be pleased to hear them. Best regards.

    Thanks to all for your helpful responses!
  4. Heller Drakkar 'Osberg'

    I recently found a complete Heller Drakkar "Osberg" plastic model kit at a vide grenier. It's the version with the lighter yellow Heller panel on the top left of the box, so from about 1971! 5€ seems like a bargain. As was standard, glue and rigging and paint are not part of the kit. l have three questions:- 1.) What glue, other than that currently sold by Heller online is appropriate for this kit? 2.) The notes say use Number 16 thread for the rigging. The inevitable Google search identifies how complex thread description can be. The only ‘16’ I can find is a weight of 16, the equivalent of Tex of 105, denier 950, cotton count of 5 and a metric number 9. Is there a more suitable alternative ? 3.) The major pieces look very shiny. Is there any prep required before painting, other than a light sanding ? 4.) What paint is appropriate for a plastic model of this sort ? Many thanks in advance for your help.
  5. Just found a nearly new copy of 'Les Bisquines' for €15.0 at a vide grenier. ( A jumble sale) Wonderful technical and social information on these working boats of the north of France. im always on the lookout for books of this sort.
  6. Fusion 360

    I have similar questions, and am currently evaluating F360 from the link kindly provided by Nirvana. Handling Bézier curves,thickening surfaces, defining volumes and transition to G code for CNC work are all important for me. I also need to understand minimum hardware spec requirements, as I am up for a new system. Watch this space.

    Thanks Nirvana. Working on it and looking for a min hardware spec.
  8. Thanks Roger. Just got my copy of Jean Le Bot's book, complete with drawings! Excellent! Thanks again for the suggestion.Williamo
  9. Hi . I have used Bentley Microstation and Autocad professionally for the last 25 years. Now I'm not working on contract anymore, I don't have access to those programs, so I am looking at less expensive options for lofting. Can an experienced Fusion 360 user let me know if F360 handles Béziers curves adequately, and is it necessary to save your work after each session, or is there an auto save facility? As I need to update my computer, any minimum spec info would also be helpful.Thanks Williamo
  10. I am an artist and designer, so I am a great enthusiast of eccentricity. It often leads to innovation! Sometimes not, but always challenging and interesting. I have done a lot of work in the area of cutting planks to shape, both in plan and variable edge profiling, as well as complete frame and hull fairing, using CNC. I have also looked at adapting these processes for full size yachts etc. I just need to find someone who makes 90 mm thick marine ply economically! I have also looked at profiling the inner surface of planks, (and the edges and ends,) then planking the hull and fairing the whole thing. I think this is the approach you are describing. Don't worry about traditional methods.They have their place, but once were innovative and poorly regarded. Pioneers are by definition out in front, and should be aware that opposition and missiles will usually come from behind, not in front!
  11. Hello Hjx , thanks for the reference. Im not sure I follow your proposed technique here. Would you machine the external profile of the strake while it was flat on the bed of the CNC? Then plank the hull? That's innovative but you must be confident the frames are accurate first!
  12. Yes. The critical thing is to have the workpiece very accurately and rigidly fixed before starting any cutting, or even a trial cut in foam first! I just have a thing about fairing hulls well.
  13. My point was that they had made a very thorough analysis of all available documentation, and may have a view on how it was built, regardless of how it ended up.
  14. It might be useful to contact the builders of the Endeavour replica, which rests at the Australian National Maritime Museum in Sydney Harbour, to see how they resolved this. Just a thought.
  15. I am currently exploring the possibilities of bevelling frame edges once frames and keel are assembled, and the hull inverted, using a CNC. Planking fairing may be done in this way too. I don't suppose this is a particularly original idea, but it would be interesting to speak to anyone who has attempted it.

About the NRG

If you enjoy building ship models that are historically accurate as well as beautiful, then The Nautical Research Guild (NRG) is just right for you.

The Guild is a non-profit educational organization whose mission is to provide support to our members in their efforts to raise the quality of their model shipcraft.

The Nautical Research Guild puts on ship modeling seminars, yearly conferences, and juried competitions. We publish books on ship modeling techniques as well as our world-renowned quarterly magazine, The Nautical Research Journal, whose pages are full of articles by master ship modelers who show you how they build those exquisite details on their models, and by maritime historians who show you what details to build.
