How would you build the top rail for a handrail of a spiral stairs

Hi Scott,

I just got back from my morning golf at Encinitas Ranch.

Here's my 360 degree spiral using an arc 3D Molding Pline. It is segmented but only 7.5 degrees per segment - it just the way the arc is converted to line segments by Chief. I'm not sure if there's a way to smooth it further but it's pretty good and ray traces well.
