You can set content restrictions for zones based on the zone style. Content restrictions can help you to ensure that only valid zone structures are built.
- Click
. 
- Click Architectural Objects Zone Styles.
- Select the zone style that you want to change.
- Click the Design Rules tab.
- For Exclusivity, select either or both of the following options:
- Space Exclusive: Define that spaces can be attached only to one zone of the style. This would be useful for zones that represent real-world space compounds, like for example a zone style for apartments. In that case, you need to prevent that individual spaces can be attached to multiple zones of that style and be calculated more than once.
If you attach a space to a second zone of the same style, it is disconnected from the first zone.
- Zone Exclusive: Define that zones of the style can only be attached to other zones of the same style. This would be useful for Building Systems applications where you want to generate HVAC and Lighting zones and want to ensure that an HVAC zone only can get attached to another HVAC zone, and a Lighting zone only to another Lighting zone.
If you try to attach a zone of the style to a zone with another style the connection is not created, and an error message is displayed on the command line.
Note: Zone content restrictions are observed in external references.
