You can use this file to simply generate a NACA 4 digits airfoil, you can generate an extruded airfoil (win section) or an array of points that you can use in Openscad or another software

USE

syntax:

Module  to generate an extruded airfoil   

GenNACA() : Generate an airfoil NACA0012 with Chord = 10 and Wingspan = 0.1
GenNACA(name="NACAXXXX") : Generate an airfoil NACAXXXX with Chord = 10 and Wingspan = 0.1
GenNACA(name="NACAXXXX",Cuerda=X) : Generate an airfoil NACAXXXX with Chord = X and Wingspan = 0.1
GenNACA(name="NACAXXXX",Cuerda=X,Extrucion=Y) : Generate an airfoil NACA0012 with Chord = X and Wingspan = Y

Function to generate an array with the airfoil points

NACA() : return the cordinates of airfoil NACA0012 in the array [[0,0][x,-y]....[1,-y][0.9,y]....[x,y][0,0]]
NACA(name="NACAXXXX") : return the cordinates of airfoil NACAXXXX in the array [[0,0][x,-y]....[1,-y][0.9,y]....[x,y][0,0]]

Enjoy
