Just an FYI from one of our gurus:
We...had a user that was unable to see the Autodesk Point Layout menu when in Navisworks. It appeared in Revit as its own tab and the contextual tab was appearing in AutoCAD as well.
For Navisworks, to get the APL plugin installed and viewable, you need to have the Navisworks service pack installed.
With this service pack installed, the APL link appeared in the ADD-ins menu in Navisworks.
