Twisting Louvre Roof with Grasshopper in Rhino 8

I’m a beginner with Grasshopper and I found a file in this group and I’m working on it to create a twising louvre. The problem is that it doesn’t match the project idea. I want the twising louvre inside the circle to be closed and the outside open, but I haven’t been able to do it. Can anyone help? Please I’m using Rhino 8. Thanks.
