The information in this article applies to:
I am creating a small room below my stairs. It will have a number of fixtures and furnishings in it, and I would like to be able to see these in plan view through the stairs.
How can I make the stairs transparent so that I can see the items that will be located below them in floor plan view?
To make objects placed below stairs visible in floor plan view, change the line style of stairs in floor plan view.
