With the Autodesk Exchange Store for AutoCAD Civil 3D 2013 we (and the users of our apps) can download and quickly use several apps! Nice! But you may notice that the ‘Add-ins’ tab is appearing duplicated, like below.
To fix it, run CUI command, (1) select ‘C3D.cuix’, then (2) select ‘Civil 3D Default’ and finally (3) click on ‘Customize Workspace’. See below.
Now (4) expand the ‘Ribbon’ list and select ‘Civil 3D Add-ins’ and finally (5) click ‘Done’. Click OK to confirm the changes.
That should do it.
If still having problems, it may be required uninstall the apps and install again to force AutoCAD Civil 3D to rebuild the CUIx.
