A display configuration is a collection of display sets that controls the representation of objects viewed from different directions in a drawing. You apply a display configuration to the viewport in which you want the objects to appear. You can also select a display configuration to use as the default for model space and new viewports.
Drawings based on templates provided with AutoCAD Architecture toolset contain display configurations for common tasks and drawing types. You can modify them and their display sets and display representations to meet your needs. You can also copy these elements of the display system to use as the basis for custom display configurations.
