After you create a metatopic, you can rebuild its structure by copying topic items from other topics. Once the topic items are in place, you can view the data model solely at the metatopic level, excluding the original topics in favor of a single metatopic or multiple unjoined metatopics.
To copy items from other topics to a metatopic, select the item that you want to add from an existing topic and drag it to the metatopic.
To select and drag multiple topic items from the same topic, press and hold down the modifier key Alt for Windows, [Option] for MAC or Ctrl+Alt for Motif while using the mouse.
