How to design Horn shapes in Blender, using tractrix formula, and exponentials

Agreed, I am trying to learn from you… those who can do what I cannot. This system is modular but a language in itself. One that I am just now discovering, but this is pretty awesome and I’m in it for the long hall.

I was asked to “apply scales” I’m like… what scales… I downloaded the thing you shared. I brought it into Blender I see

but have no idea what to do with it. If I tried using it to replace the module that looked similar from what Dan2 contributed and it made the Squircle in 2d form after some tweaked, but nothing extruded. Obviously nothing you did wrong, I just don’t know what I am doing.
