Winder stair in 3D - bug?

[Anonymous]

Hi,

Surely this is a bug. I have used the stair tool to create a stair with a winder at the top and bottom. It looks perfectly fine in plan. But in 3D it somehow skews the underside.

Anyway I can fix this? I'm on ARCHICAD 20.

Thanks,
Ben

Thanks Alemanda.

Does anyone know if this is a confirmed bug up to ARCHICAD 20?
