Display by Elevation (DbE) was introduced in AutoCAD MEP 2009 for Ducts & Duct Fittings. This feature has been enhanced to now support Pipe & Pipe Fittings, Conduit & Conduit Fitting, and Cable Tray & Cable Tray Fittings. You can use DbE to accurately represent items in your construction documents without creating new layers to control color, linetype, etc. For example, chilled water piping routed underground can be shown dashed or hidden while piping above grade can be shown as continuous, all on the same layer.
When enabling DbE the existing display components are replaced by four elevation dependent display components; Below, Low, High and Above. These display components can be turned on/off individually or configured to use different layer, line type, color, etc. The Above and Below Display Ranges and Cut Height in the Cut Plane dialog box are used to determine
which of the four elevation dependent display component to use for an object. These values can be defined on different levels in the display system:
‐ Global: Setting for all objects in the drawing
‐ System: Override for all objects using a specific system definition
‐ Object: Override for individual objects

Rise\Drop Display controls: In addition to the checkbox to drop tees/takeoffs, you now have the ability to show Rise symbols under MvParts and Endcaps for Ducts, Pipes, Conduits and Cabletrays. Each discipline is controlled separately, allowing for the better creation of construction documents.
