The Drawlist window lists the names of items displayed in the 3D View. Adding an item to the 3D View (by dragging from the Model Explorer) automatically adds the item to the Drawlist. Individual elements can be added, or an entire Zone or Site.

To display the Drawlist, on the 3D View tab, in the Contents group, click Draw List to display the Drawlist window.

Refer to Drawlist for further information.
