stairs problem - how to solve it?

Hi, 

Is there a way to solve the situation o the image?

The only real solution I have found is to model the flights and winders separately.

If all one stair, the underside will become curved.

If modelled as separate stairs, the flights will have a flat base and you can edit the winders to have a flat base as well if you want.

Thank you Barry

If you use Barry's method, some landings may become very thick. In that case, you can even model the desired bottom surface with a Morph and subtract it from the Landing to achieve the exact desired bottom surface in all landings instead of the automatically generated bottom surface.
