I wanted to draw a simple hydrofoil design (in 2d to begin and then if the profile is correct make a better 3d version) from coordinates to export it to ansys a cfd software. As expected something went wrong, it says that the foil override itself and can't be drawn, even if i adjudt the points so if anyone knows how to do it thank you very much ! ( I still managed to draw the foil but in two pieces so it's not very practical ) here are the coordinates : http://airfoiltools.com/airfoil/details?airfoil=n63412-il
