I used “Convert to: Curve from Mesh/Text” to convert some consecutive edges (a polyline with perpendicular corners) and use this with an array to create a banister for a balcony.
But, in the corners the banister curve and doesn’t go perpendicular the curve…
Why dont you just throw a couple corner posts in and use straight runs? Separate it into 3 runs. Also, that long of a run without posts in teh middle is against code…lol
