A zone template is a structure definition for zones with multiple hierarchical levels. You define the zone template as a hierarchy with certain properties, and use it to create the zone structure in the drawing.
Zones according to DIN277
You use a zone template only to insert a zone structure. Later changes to the zone template are not copied to existing zones based on this template.
Similarly, when you change a zone structure that is based on a zone template, those changes do not affect the template.
You can create zone templates for structures you need frequently, and make them available through AutoCAD Architecture 2022 toolset style drawings.
Note: Area group templates from legacy drawings are automatically converted to zone templates when the drawings are opened in with the current version of the software. Area name definitions that were attached to an area group template will be disconnected from the zone template, as name definitions are now attached to the space style or the zone style rather than the zone template.
