Someone asked this question today.
How do I get the dwg setup menu and display manager/viewport scale menus to display at the bottom of the AutoCAD Architecture or Architectural Desktop interface?
Apparently, these items had disappeared from someone's profile - see image below:
These interface components are part of the main customization file...when these items disappear, the chances are real good that the main cui file is no longer an ADT or ACA file. I suggested reloading the profile.
