UE5 - Spline Railing with Geometry Script and C++ (Part I)

I built this cool rounded railing using some trial-and-error, math, and fancy Unreal Engine 5.1 geometry script tools. I decided to record this tutorial after I had some success programmatically modifying the spline from C++ (which happens in Part II). It makes the railing shape simple to edit (just a single spline) while still boasting its nice rounded shape.
I'd be interested in seeing a Blueprint-only version of this, if anyone knows a simpler way to create the nice rounded corners! I'm sure the way I built this isn't necessarily the best, let alone the only, way.

Yo! This one is pretty usefull and there are not a lot of usefull geometry script videos on you tube. So thanks.
