Yet another tower… 
I can see from your recent code in the duplicate thread that you missed some important points so I created one of the tall towers, then used ArrPolar (Polar Array, white group) to get four copies.

This is by no means the only way to do this.
Again, please do not internalize the geometry created by this model. The GH file size is quite small.
P.S. Here is a very simple variation where the angle and scale of the middle section can be controlled independently instead of being half of the top section values, as in version ‘a’ above.
