Answer:
To add your Menu Bar first you will set the command MENUBAR to 1. Then you will navigate to the CUI editor by using the CUI command to add entries to the menubar across the top.
-From here you will then navigate to the “Transfer” tab
-On the left side you will see your Main CUI loaded and “New File” listed on the right side
-On the right side you will click on “New” pull down and select “Open” to navigate and select “acad.cuix”
-This will then display the Main on the left and the acad.cuix on the right for transfer
-Transfer the menubars (or a selection) from the acad (right side) to the main cui “menubar” section
-This will then add in all menubars you are looking for from the core ACAD software as used in previous release of the software (creating a classic view).
