Connecting Curving Columns to Surface Edges

Hi! I am still just learning grasshopper and would like to add a couple curving columns along the edge of my tower (and if possible on the edges of the middle gap). I want it on the edge of the merged-shape tower. Any help appreciated!

I’ve attached my file, the non-grouped part is what I am working on.

It’s better if you draw and show what you mean

yes that’s what I hoped for, possibly less in number but exactly that! Would you mind please posting the script?

Control the number with divide count
