Default Sets are collections of Saved Defaults that allow you to quickly switch the Active Defaults for all of the following text-based objects at once, as well as the Layer Set and Current CAD Layer: Dimensions, Rich Text, Text, Revision Clouds, Callouts, Markers, Notes, and Arrows.

Saved Plan Views are preconfigured collections of the following settings, allowing you to quickly change them all at once as you create a variety of construction drawings: Default Set, Layer Set, Reference Display properties, and general plan view-specific settings.
