well I got the geometry from the the sailmaker where I want to let them manufacture this sail. then I flattened and spring with ExactFlat (geometrically precise unfolding, no Rhino Smash) but it occured that the delivered DXF files for each panel where not 100% congruent with the flattend one for one strange reason, so as you might understand from the previous threads on this project, I had to find a way to fit the flatted textured into the original DXFs… I wanted to invest 1-2 days, and it took almost 1,5 weeks
