Stairs - Curved Structure

Lingwisyer

Hi all,

Regarding AC21+ stairs, you can modify the shape of treads and risers, but how do you go about getting the structure to match?

I am trying to make some stairs where the edges curve out to create a wider stair at the bottom, and each tread curves forward, much like you might see at the bottom of a grand staircase, but I have only been able to curve the sides of the structure within the originally defined stair length. The start and end nodes of the structure appear to be locked to this length...

Stair boundaries can be curved but the start and end nodes will always be at the bottom and top tread (stair extent).
The stair treads will always be perpendicular to the stair baseline.

You can curve each tread and riser but the underlying structure will not curve.
Normally I guess with treads and risers active, you wouldn't have an underlying monolithic structure.

So if you want curved treads on a monolithic stair with no tread or riser finishes - I don't see a way to do it.
Maybe I am missing something?

Is there some way to lock the riser to the tread? Curving the front and back of every tread, then doing every riser is rather time consuming... This also makes most of the riser settings useless... And is there a way to have the Tread Edge always follow the Stair Edge curve?

Not that I am aware of.

Once you have amended a tread shape it will no longer follow the stair boundary.
As far as I know you will now have to edit each tread again individually.

I can't even see any way to 'reset' a tread to match the boundary again.
If anyone knows a way please say how.
