As far as I see it is not possible to have closed curve railings. Overlapping start and end points can be a fake ‘closed curve’ as a workaround but open corner is not proper in terms of detail. Any comments about it?
Yep, I haven’t found a proper solution yet.
It is not possible yet to create railings from closed curves.
