I know it's based on underlaying an image but you can adapt it to a 2D plan of the stairs too...

The soffit part is explained in the end section of my stair tutorial skp - copy the treads down select edges move 'up' with alt for auto-folding etc

Its work, but soffit has a few faces. Must wait for Curviloft from Fredo (amazing thing). Its what i need

If you make the top and bottom 'tread' lines into 'curves' with ' weld.rb' [divide the 1 edge into 2 or more pieces first], and also make 'curves' from the two side 'stringers', then you can use my ExtrudeEdgesByRails [part of the Extrusion Toolset] - then you'd pick the bottom 'tread' as the 'profile', then the stringers as the two 'rails' and finally the the top 'tread' as the 'melding-profile'... It should form a mesh face to suit... Here's a quick example...
