To Exchange to a Reference by Using a Key-in

Do one of the following:

In the active model, enter the key-in, REFERENCE EXCHANGE <file_name, model_name>
Enter the key-in: XD=<file_name, model_name>

Note: Where the file is referenced once only, the model name is not required. If the file is referenced multiple times and the model name is omitted, the first instance of the reference is assumed.
