Name, Number
Enabled: The name or number from the respective room is transferred to the corresponding space. The variables and can be combined. If you enter the name MEP_ and the number (), for example, the MEP rooms will be named MEP_Living Room (3).
By using curly brackets, you can apply any text parameters from the associated rooms (rooms or lfcSpaces, for example) in the room names and room numbers of the spaces. The exact names of the parameters must first be determined in the Revit Properties or in an IFC viewer using sample rooms.
This method can be helpful, for example, if the linked architectural model does not use the standard name and number parameters. Examples of this from actual practice include IFC architectures in which room names are stored in the LongNameOverride parameter and the room numbers in IfcName. In such cases, the syntax should also be applied as shown in the following image.
