So far, we've used the logical workspace to create topologies. The physical workspace makes your logical topology more realistic by giving it a physical dimension. The physical workspace has four environments: Intercity, City, Building, and Wiring closet.
Intercity: This is the largest environment consisting of cities. Cities, buildings, and wiring closets can be created in this layer using the controls on the toolbar.
Cities: This layer contains buildings and wiring closets. The default city is named Home City. Cities can be dragged and placed anywhere on the intercity map.
Buildings: This layer contains wiring closets. The default building is named Corporate Office.
Wiring closet: This is the final layer that contains devices placed in the logical topology. Its default name is Main Wiring Closet and it doesn't have any specified area.
