Tabs on Louvers...Again!

I am not looking at new files you posted in this thread, I am referring to the file I posted in the original thread: Parametric

Here it is again, slightly easier to read: [see version Parametric in next post]

If you understand that file completely, you won’t get lost when your “louvers” are oriented differently.

One thing that experience tells you (among many others!) is the benefit of using a base plane that all subsequent geometry is built on. You didn’t do that and I didn’t do it for you, which makes the task a little more difficult - but still far from impossible! This is a rather simple model.
