Style-based content in AutoCAD Architecture 2022 toolset is classified under one of three general groups. 
-  Architectural Objects: Traditional architectural object geometry. 
 
-  Documentation Objects: Any style-based object that is specifically and uniquely used for annotation and documentation purposes. 
 
-  Multi-Purpose Objects: Any style-based object that could be used to help define either a documentation object style or an architectural object style. 
 
Many styles can be used to create style-based tools on a palette. Others are used as nested styles or substyles. All styles and definitions can be edited in the Style Manager and stored in a central style library drawing. 
Tip: You can assign a pre-defined keynote from your keynote database to any style that you create on the General tab of the style definition.
