System of measurement
To toggle the system of measurement used in the client, select Tools>Preferences>General and set Client Settings to display floor dimensions in meters or feet.
All floor dimensions on the Data Center Operation client will display in meters or feet according to this setting (metric/imperial).
If you want to see some rooms in metric and others in imperial, you can use different clients or toggle the setting before opening the various rooms.
Default wall type
To predefine the wall type of any wall added to the room layouts, select Tools>Preferences>General and set Default Wall Settings to enable a specific wall type, such as standard mesh.
Alternatively, in Genomes, right-click a wall type and select Set As Default to apply the properties of this wall type to any new walls created.
A green check mark icon on the selected wall in Genomes illustrates the active default setting.
This setting applies to you. Other users in the system can have a different default wall type.
