OK Gang! Because no matter how 'perfectly' I set up a wing ( elliptical again) I never get either stitching or a proper extruded airfoil ( 150 points/ lines per foil) to 'land' on Z Zero, so I figured I'd try to play surfaces. Once I got my surfaces collected the best I could, I tried a surface intersect with an infinite plane(s). CArash! here's the result. I can setup a small file, but it's going to take about 4 hours to return to my last save point!- Yes, things were going smoothly, and I purposely did not save before the intersects!
More if needed!
