Only the layout shows the deleted wall. I copied the walls on the 5th floor to the 6th to 35th floors using "edit element by story". After that, I deleted the wall on the 6th to 35th floors. I selected it from the elevation and deleted it. After that, I can only see the deleted walls in the layout. And I drew three walls on the 10th floor for the test. But this time, if you place a floor plan on the layout, all of these walls will appear on the 10th floor or more.
However, if you erase the walls on the fifth floor, the walls on the upper floor disappear. In the layout... And if you draw a wall on the other floor, you'll see it all up there. In the layout. All walls are 3D, invisible from the floor plan. You can only see it when it's placed in the layout.
I want to attach this file, but I can't. It's more than 5MB.
Thank you very much for the question and I am very sorry for the issue!
Same as Rajesh, I checked the given zip file and it turned out that the zip file is corrupted. Thus, upon extracting, Archicad can no longer read the file. Could you please try to reshare the PLN again? If it is still not successful, I will share a special link with which you can upload the file to us.
