Sailboat hull

thingiverse

The original DXF file was imported into Scad using a scad macro that wires frames/bulkheads through a sailboat hull. This macro generates the hull shape from the sections, making it worth taking a closer look even though it needs further work. The original file exported from Carlson Design Corp's Hulls program (highly recommended at http://www.carlsondesign.com/hulls.zip) has each section on its own layer. The longitudinal sections are used for both the stem and stern because the sail boat is double-ended. As the hull curves inward toward the keel, it builds up in layers. At the beginning of this Scad file, you'll find the parameters with units set to inches! In Version 2 of this code, importing DXF sections gave way to using a table of offsets to plank the hull. With millimetre units, the method now makes it possible to implement a simple spline and smooth the hull between bulkheads in the next step. Version 3 further adds a spline that can be used to interpolate frames, giving a smoother finish on the hull when new frames are added. It's suggested you zoom way out while viewing this full-sized hull due to its size. Scad has turned into more work than expected, so it might be time to look for another program. Any ideas would be welcome!
