algorithmic modeling for Rhino

Dear All,

I have to make a space frame, around a cylinder surface. I have a problem with lines between centers and edge points. I need to have pyramids, through centers of one surface to edges of another. It's a basic question probably. Anyone knows how to solve it?

Thank you

Because you build your two surfaces differently (one through a loft, the other with a surface offset) your domains don't match between the two (if you bake your geometry into rhino you'll quickly see that the seams are opposite to one another); this is why the centers of the interior surfaces don't correspond to the edges of the exterior surfaces.  If you construct your surfaces using the same technique you should be okay.  I've made a couple of quick adjustments to yours and am constructing the surfaces by extruding circles of different radius...this ensures that the seams match up.
