2D Frame Analysis

Hi all,

I am a student completing a research assignment into ideal stiffness allocation between the exoskeleton and the core. I thought grasshopper and karamba would be a good way to do this. I am having some problems I am hoping someone can assist me with. When I shatter the members so as they intersect with horizontals only the external columns come through into the structural analysis, not the internals as well, even though i can see from the shattered output that they have been shattered correctly. The way the parametric sliders are set up currently there should be 2 internal columns, but none are appearing in the analysis just the external ones. Anyone have any idea why?

Any help would be greatly appreciated,

Thanks, Felicity.
