The Add Tab Only option displays the ribbon tab as its own tab, while the
Merge Tab Only option merges the ribbon tab with a ribbon tab in the main
CUIx file that is assigned the same alias. The Merge or Add Tab option attempts
to merge the ribbon tab before a new ribbon tab is created on the ribbon.
NOTE You might need to use the CUILOAD command to reload a partial CUIx
file in order for the ribbon tabs to be properly added to all existing workspaces.
Reloading a partial CUIx file will affect the display of all its ribbon tabs.
The Plug-ins ribbon tab found in the acad.cuix utilizes the concept of merging
multiple ribbon tabs from all the currently loaded CUIx files into a single
ribbon tab. If you create custom applications, you can merge a ribbon tab that
contains your commands on it with the Plug-ins tab.
If you want to merge your ribbon tab with the Plug-ins tab, change the
following properties of your ribbon tab to:
■ Default Display: Add to workspaces
■ Workspace Behavior: Merge or add tab
■ Aliases: ID_ADDINSTAB
NOTE You can merge any number of ribbon tabs together as long as the aliases
are the same.
