Navisworks is pretty amazing at handling a huge set of properties across a large amount of elements. However, sometimes it can be hard to diagnose why a particular parameter, such as a Shared Parameter, is not displaying or grouping in a way that you might expect.
Now, when you use the Properties palette you will see additional information in brackets, which essentially amounts to the Navisworks ‘internal parameter name’ for a given piece of data. Pretty cool!
