While some of the new BIM360 and Navisworks integrations are welcome, there are certain pieces that are still missing. It would still be useful to be able to Glue an individual model to a Glue host in Navisworks 2016, rather than having to sync with a Merged Project and interact with the Glue host in only that way.
There could simply be an additional button in the Glue addin ribbon to Glue the current model, no matter what that is: an individual NWC, DWF or NWD, or some other model type.
