AC21 Stair and Railing Tools

I am trying to model an open tread stair with a glass balustrade that is just glass panels, no posts or rails, clamped in to the steel stringer. I can make the stringers but cannot find an option to remove the risers in edit or main options.
A second question - how to make the solid balustrades as seen in the current AC21 signature image ?
Grateful for any help,
Peter

Try Stair > Finish > Tread option (for Tread, Riser, Tread and Riser).

Thanks David

But I don't get the same image as you in the stair options window

I also notice that I don't have the Stringers-Flight option under Structure

OK I'm getting there - I have removed risers by setting thickness to 0 mm in the edit mode but it feels like cheating to me. And I have a twin crémaillère (beam) type construction in place of stringers.

Now for my glass panel railing …
