I want to display the wall below the slab as a hidden line.

This is the roof layer.
1. I want to display the wall below the slab as a hidden line.
2. I also want to show the wall under the beam as a hidden line.

As shown in the picture below, when the slab covers the beam, it becomes a hidden line, but the wall is still visible as a solid line.
Since the wall is below the beam, I want it to be displayed as a thin hidden line.

I don't think it's the right way to do this because it seems like you have to create it for each layer.

What I am thinking is that I want to show the walls below the current floor as hidden lines.

All you need to do is use one of the parameters or properties of the Wall for this. Here is an example, where I set the Element ID of the Wall to "Hidden" and created a Graphic Override that overrides the Line Type and Fill of Walls the Element ID of which is "Hidden".

You can also use a newly created Property for it, which may be a better choice if you want to use the Element ID for IDing purposes.

I think the correct answer is that the wall below the current floor must be hidden.
The ID you mentioned is downstairs now, but on the lower floor it becomes a single-sided wall. In other words, I think there are problems that require creating settings for each floor.

What I think I need is that I want the condition below the current story.

I wish you could recommend something other than id.
This is because the id must contain the wall name.

[Laszlo Nagy]

You could also create a Property and override the graphics of the Wall based on the value of the property. That way you would not have to use the ID for this purpose.

Thank you for the reply.
In your answer, I heard that there are cases where the wall has more than two floors, so I tested it.
So, I found out that there is no problem in the case of cross section, but there is a problem in the wall that becomes the elevation.
ArchiCAD always keeps me on my toes. ^^

The wall elevation line does not appear at the end of the wall.(right)                                                                         

This is just a test.
There is no problem if the wall is built on the upper floor.

The new problem here is
display order
slab, beam = 7
wall = 8 .
There is no problem on the drawing. Because it's black.
But I guess it's just my personality that doesn't like being eaten by those below me.^^

display order
slab, beam = 7
wall = 8 .

                                                display order
                                                           slab, beam = 7
                                                                      wall = 7 .

I also found out that even though the column is connected to the wall in cross section, it is not connected to the wall in elevation.
ArchiCAD always lets me know that what's over isn't over. ^^
