Stair rendering issue

[naomihansen]

Hi,

I'm stumped by this problem and am hoping to find some leads here... 

We have a project we've been working on since 2017, which means the file has been migrated several time to new versions of Archicad. The stairs that used to render just fine are now defaulting to zero thickness and default (brick) material. I tried changing the parameters, and the preview in the stair settings look fine, but then the model will not change. I even copy/pasted a stair from another project which was started much later and even that stair lost it's data. Anybody have a clue why this might be happening in this file? 
Attached is a screenshot of the problem file (with project stair in the foreground and the second stair, pasted from another project behind) and a screenshot of the other stair as it should look (hint: not paper-thin brick).

Check your Model View Option settings for the stair options

You might find it is set to schematic.

The same applies for railings in the railing section.

Yes! Thank you, this is exactly what the issue was! Since only the stairs were affected, I did not think about checking this. 

Thanks again!
