hi all. just to give you a quick background. i just got a new laptop, and upgraded to the ultimate design package. i have been through all the tutorials that i can find. i have a couple issues. 1st with this installation, for some reason the add-in for exporting to navisworks is not loaded in revit like it was in my old versions. 2nd i tried opening the building that i completed in Revit with Navisworks. for some reason the only part of the Revit file that appears in the Navisworks view are the grids. and the Structural model that was done with Autocad will also show up in Navis. i'm completely lost on this topic. any help would be greatly appreciated.
