How to create Space frame?

I'm looking to make a space frame from a rhino surface. So far, it has been possible to generate a single layer dia-grid. I'm looking to extract center grid from surface points then move in the normal direction of that center grid.

I have been looking into "evaluating surface" method from the tutorial (http://www.pxleyes.com/video-tutorial/rhino/8688/Create-a-Space-Fra... ) however when I connect 'Explode (Brep Components).F (Surface)' into 'Eval (Evaluate Surface.S (Surface)' I'm not getting the desired effect.

I've attached screenshots for further illustrations.

Any suggestion would be much appreciated. Thank you.

Hi!Did you manage to solve your problem with diagrid? I'm trying to do an irregular surface division and having multiple issues, but it works just fine when I divide it regularly. First of all I'm facing an issue with surface normals, it gives me more than one.
