Display Representations
Display representations represent the first level of display control. Display representations define how an
object appears in a drawing.
You can also preview display representations by clicking (Floating Viewer) in the Display Manager. The
Floating Viewer displays how a specific object appears in different display representations and view directions.

Architecture Help.
