One option
Autocad has "2" spaces, Model and Paper it might be that your client is not looking at the Layout but the model view. This refers to the "Save layout" option on AC's publish settings.
It is the same answer you would give someone using AC, you ask them if they are in layout view. If not export from AC using the "Model" option.
The mistake might be that you are assuming that "they" know how to used Autocad…
