About Workflow for Displaying Objects Based on Elevation

Review the steps   View more information
Enable the Display by Elevation feature.   Select Enable Display by Elevation to differentiate objects that are placed above or below the cut plane in the layout. See Enabling the Elevation-Based Display Components.
Set the criteria that determines how objects display in the drawing area based on elevation.   For each display configuration that uses 1-Line or Plan display representations in Top (plan) view, enter a cut height as well as height ranges for above and below the display range. See Setting the Cut Plane and Display Range for a Display Configuration.
Configure display components for each elevation-based object in the drawing.   In the 1-Line and Plan display representations, configure settings for display components. For example, specify linetype or line color values to differentiate objects based on elevation. See Configuring Elevation-Based Display Components.
Allow for exceptions to the display configuration.   Configure overrides for cut plane and display range values. See Applying Cut Plane Overrides.
