To include UniqueId in Glue viewer, you will need to specify it in the Navisworks exporter options. (Make sure you install the latest version of 2015 exporter and above.) But it may not be so obvious as UniqueId is not included by default when importing/exporting to a Navisworks file.

With the enhancement with Navisworks exporter, it is possible to include it and view in Glue properties dialog. “ How can I access Revit UniqueId in Glue?” is one of questions I get occasionally. For example, to realize a round trip between Revit model and an analysis program, you may use UniqueId to identify the existing elements. ( Jeremy Tammik describes this topic in detail on his blog.)īeing able to identify each element by UniqueId is important for many API users in order to link external information to a specific element. But as stated above, they differ from UniqueId. Other properties, for example, Element ID, is not guarantied to be unique. It was added for API users in order to uniquely identify each element. But it actually has additional eight (8) characters at the end. As the name suggests, it’s an unique identifier of an element in Revit. Every Revit element has a property called UniqueId.
