Share 'splitting a polysurface'

hi,I'm wondering how the easiest way to split a referenced polysurface? The goal of the definition is to split the referenced geometry (a polysurface), and lay out both curves and geometry for each layer, for milling purposes.I could take the bottom and top curve from each 'layer' and loft them, but then I wouldn't get the exact curvature of the surface.Is it possible to split a polysurface in to…
