Exceptions
Exception Condition
ArgumentException The server referenced by the ExternalResourceReference does not exist or does not implement IExternalResourceServer. -or- The server referenced by the ExternalResourceReference cannot support Revit links. -or- The ExternalResourceReference (resourceReference) is not in a format that is supported by its server.
ArgumentNullException A non-optional argument was null
FileAccessException The model cannot be accessed due to lack of access privileges.
ForbiddenForDynamicUpdateException The function is not permitted during dynamic update.
InvalidOperationException This RevitLinkType is not a top-level link. -or- The link "this RevitLinkType" is loaded into multiple documents and cannot be reloaded. -or- The element "this RevitLinkType" is in a closed workset. -or- There is a transaction phase left open (such as a transaction, sub-transaction of transaction group) at the time of invoking this method. -or- The document is read-only. It cannot be modified. -or- The document is in an edit mode or is in family mode. -or- Revit cannot customize worksets for this model.
Remarks

If the link is currently loaded, Revit must unload the link before reloading it. Any changes made in-memory to the link's shared coordinates will be discarded.

Revit does not try to validate that the input represents the "same" document. You can load a completely different document, which may invalidate references to linked elements.

This function regenerates the document.

The document's Undo history will be cleared by this command. As a result, this command and others executed before it cannot be undone. All transaction phases (e.g. transactions transaction groups and sub-transaction) that were explicitly started must be finished prior to calling this method.
