I would not use the DBCA to do this task because it cannot be used to duplicate anything. Instead, use the Oracle export utility. The following will duplicate the structure without data:

exp file=my_db.dmp full=y rows=n

The ROWS=N parameter will not export any data (no rows). The structure will be in the dump file though. Oracle's import utility can then be used to import the structure into another database. Please refer to your version's Utilities Guide for more information on these two utilities.
