Columns to Roof pattern

Hello!

I am very new to grasshopper and following some tutorial to achieve the result that I want but failed. I am trying to connect this curved roof with the columns to create structure. Columns currently are just these circles marking the place they should be, and the top circles are just the edges where they should meet the roof.

Hopefully this image explains the column in the file.

This is how I want the roof to meet the column.

I followed this video to connect both in this “wood” structure pattern.
