    I'm not disagreeing that NURBS make this easier but, It's not strictly a requirement. The curves workshop in FreeCAD does use actually employ NURBS so, it fits the bill anyway. One can get closer to an accurate hull from tracing a set of body lines or importing a table of offsets in FreeCAD because the curves workbench's tools will create splines that actually pass through those points and you can then use a Gordon surface to "loft" those splines together into a fair hull shape. Delftship on the other hand interprets your coordinates as "control points" and the curves will almost never pass through them : (

    um... FreeCad : P The curves work bench does the math for you and converting the resulting surfaces into an STL file, which is a polygon format, is fast at reasonable resolutions. The hull above has been printed in sections to make a 4 foot long physical model. Well 2 of them so far and a 3rd one in progress.

    So back to FreeCAD, it is a very powerful set of tools. It's a little different but once you get used to the concept of workbenches, you won't go back. The curves workbench is fantastic for turning 2D Body Plan lines into graceful 3D shapes. There are excellent tutorials out there. MangoJelly's, in particular, were extremely helpful to get me to the point where I can loft nice looking hulls with complicated curves. https://www.youtube.com/@MangoJellySolutions

    @Jaager Which volume of the CDs would have that information?

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 “Advance Ship Modeling Through Research”. We provide support to our members in their efforts to raise the quality of their model ships.

The Nautical Research Guild has published our world-renowned quarterly magazine, The Nautical Research Journal, since 1955. The pages of the Journal are full of articles by accomplished ship modelers who show you how they create those exquisite details on their models, and by maritime historians who show you the correct details to build. The Journal is available in both print and digital editions. Go to the NRG web site (www.thenrg.org) to download a complimentary digital copy of the Journal. The NRG also publishes plan sets, books and compilations of back issues of the Journal and the former Ships in Scale and Model Ship Builder magazines.
