generative modeling for Rhino
I was wondering, if your offset is in the right direction?
And which curves do you want to use for which surface? :-)
Maybe I misunderstood what you need. Do you want to "map" some Voronoi cells to a surface and then you want to get outside these cells surface/s (that's what I understood you tried by planar/loft)? Am I right? Was the previous post useful?
