All my walls are gone

[Cosmin]

Hello,

The problem I'm facing is that all my walls disappeared after I dragged and dropped the ground floor to an A3.

It looks like this:

If I want to draw a wall, I get the message : 

Than if I go to the Floor I get the same message if I want to draw a wall.

I went to "Document, layers , show all layers" but it still doesn't look the same as it should 

I don't have just one house drawn in this project; all the walls are gone.

If you could help me, it would be appreciated.

Thank you,
Cosmin

That error normally appears when the layer set in your tool (in this case the Wall tool) is hidden in your current view’s layer combination (LC) when you are modeling. Best to edit and Update your modeling view’s LC, then make sure your saved view has that same updated LC assigned in the View Setting. This helps to ensure whenever you re-open or want to restore that view, you have the expected results. (If it’s a cloned plan set view group as you are showing, select the top line of the group to assign and it will cascade to all the floors under it.)
With that, then check the drawing layout source view (if different) to ensure it has the appropriate LC in its View Settings. Then, Update the drawing to show the results of the updated LC (with the layer you were missing).

Another thing to check is the home story assigned to the element and the Floor Plan setting.  It easy in some situations to have an element appear to be on the current story, but in fact, be on another.
