Otherwise it’s rather useless. Linked files retain the reference to the external files and will update when the Revit model is reopened or the linked file is reloaded. Imported files become a part of the Revit model and lose any connection to the source.
The decision to import or link a file to a Revit project affects what you can do with the xref information:
- If you import the file, you can explode the nested xrefs to Revit elements. …
- If you link the file, Revit automatically updates the geometry to reflect changes to the xref files.
