Viewpoints can be imported into Autodesk Navisworks via an XML file, enabling you to bring viewpoints into the current scene from another model file. For example, if you are working on different versions of the same model, you can save viewpoints in one version of the file, export them and then import them into the other version. See Save Viewpoints for more information on saving viewpoints, and Export Viewpoints Files for more information on exporting viewpoints to an XML file.
