Balusters on curved staircases is a bit challenging, I'm not going to lie. My algorithm(s) are mostly working, and I think, as I suggested in my previous postings, I will need to add in some additional (curved stair specific) parameters. At this point I really hate to add more parameters to these already substantially bloated menus. Too many settings and options tend to overwhelm the casual or new user, but at the same time we need enough controls or knobs to fully adjust these assemblies, its a bit of a trade off I guess. As the Japanese say "Shikata ga nai" (仕方がない).
This screenshot is of a "circular" curved staircase with 1/2" square balusters and baluster shoes. As you can see the baluster spacing is not quite right for either side (inner and outer handrails). To get exactly 2, 3 or 4 balusters per tread one will need to carefully and probably iteratively adjust the spacing. Since these arc lengths won't be nice even numbers the exact spacing number will be some fractional value. I've got some ideas on this to make things a bit easier for the user to compute these exact spacings but I need to experiment with it further.
Its funny how when I start down one of these rabbit holes I don't usually don't know the full solution to the problem or even fully understand the problem itself. But as I slowly unravel and work my way through one of these problems it ultimately becomes clear and then along the way I seem to always find better ways to address the problems that I encounter.
