How can I associate these projected points on the surface to the points of the structural mesh (same surface) to generate continuous surface columns?

Hi guys, how are you?

I just got into grasshopper in a few days and I am trying to modeling a structural mesh with column surface (as for example Centre Pompidou Metz).

I had projected the points into the surface but I am not finding a way to accomplish the points of this mesh to the column points that was projected into the surface. Do you guys would have any tips for me? I would really appreciate that.

I am really trying but i got blocked at this part. P.S: I defined the grid of these points but it seems that the number 36 is a pattern number for the grid. Is that true or I can figure out another number? I would like to have just 2 or 3 columns! Thankyou so much for the help guys. Really! Best wishes, Pedro.
