Problem when using Boolean intersection for a model of the Eiffel Tower

Rhino
1

Hi

I am currently working on a simple model of the Eiffel Tower, using this tutorial as a reference:

Rhino基礎-03 交集應用 (Eiffel Tower 艾菲爾鐵塔)

I remember the process working at first, but it’s not working on this second attempt. Could someone review my model and see what’s wrong with using the Boolean intersection?

This is pretty easy using trim and join.
I would be surprised if booleans worked.

Thanks, after seeing your answer, I decided to try this method to see if I could achieve the same result and it worked.
