I don't know what the problem is with my algorithm

[배수현]

I am the person who said yesterday that I wanted to practice a structure similar to the image in question.

I’m working on it somehow, but is there a problem with my algorithm? Is it right to proceed like this?

Now I don’t know what to do to move on to the next step.

My polygon looks like this now…

And after installing Paneling Tools, my Rhino became very slow. Why is this?
