Stair 'draining' display in plan

[Paul King]

I am trying to show stair gutters in plan views.

They show fine in 3D, but in 2D views there is no clue as to their existence. 

There is an (annoyingly) closed topic already on this issue, which appears to be a known bug, that appears to give false or at least superseded workaround information as the 'marked solution'.

The marked solution refers to ensuring the stair has a finish (even in tiny thickness), and adjusting Model View Options (Detail Level of Stair and Railing Symbols=>Structure - Monolithic) setting to show 'Visible and Hidden Parts'.

However doing both these things has no impact at all.

What solutions work in ArchiCAD 29?

Yep, I found the pens, thanks.

The 'built-in' objects are just there so the stair (and railings and other objects) will work if no libraries are loaded.

It uses a 'built-in' library that you can't un-load that basically just store default parameters.

But not all parameters as we have discovered.

Barry.
