I immediately thought that it would be quite a task to make this stair with Revit's stair and railing tools. Ironic that such a stair is "under their nose" and certainly should serve as inspiration for any future improvements that are made.
On the same subject, while working in Houston in a Philip Johnson/John Burgee building originally called the Transco Tower and now called William's Tower I encountered a stair in an emergency exit stair shaft that has what I think is a very nice railing detail.
This is the stair/railing from one angle
This is another angle
I imagine you could make separate railings that use custom start and end balusters to replicate the transition from run to run but it would take a bit of work. The connection of each stringer to a flat plate just isn't possible with the current tools. I like the fact that you can walk down the stairs and leave your hand on the railing without ever coming into contact with a support, very clean.
If you are curious here is a picture I took of the tower itself. I took it from next to a parking garage nearby.
This is a view from the 62nd floor meeting room we used for training, looking East toward downtown Houston.
The top row of glazing in the immediate view to the right is the parapet of the floor/roof below us. On the roof hidden from view are the anchors and outriggers for the window cleaning rigging equipment. Sorry, no picture...didn't think of it till now, too late!
If you have a stair or observe one that Revit ought to let you build at or all, or at least more easily, consider taking a snapshot of it and/or providing the design drawings you prepared to Revit support so they can properly define the scope of any future improvements to the stair/ramp/railing tools.
