Hello,

I have created an airfoil from a 2d set of points and a 3d set of points and then lofted them to make the surface.  The problem is at the trailing edge of the airfoil the loft seems to have cris-crossed the final few points (second to last point on one side goes tot he last point on the other and vice versa).  Can anybody explain how i fix this.  I have included a zip with the files.
