Getting Curves from Polysurface

I have a polysurface that was lofted. I would like divide this surface every 6" or so and get the outline of the surface, so I can then use the Rod function. I tried extracting isocurves from the surface, but it will not do the entire outline, just one surface.

Yeah, you’ll have to jump through some hoops - Make a vertical plane through one side- just a little bigger than you need. ArrayCrv the plane around an elliptical edge curve from the object. Then, IntersectTwoSets to get the curves.
LIke so -
