I just installed Revit 2010 and Navisworks 2010 (in that order) on my machine, and I'm having no luck finding the Navisworks exporter tool within Revit. In previous versions, I would go to Tools>External Tools>Navisworks, but in Revit 2010, there doesn't seem to be a Tools menu, or any way to switch back to classic interface so I could access the Tools menu.
Any ideas? Anybody else having this problem?
