I would like to select multiple zones which have the same Name (Attribute). I am faced with a challenge in wanting to find and select zones with the same Name (Attribute) because the IFC Properties option is "greyed out." Please help...
What you can add as criteria is dependent on element type. Not sure why IFC Properties can't be added for zones. However, you can start with it set to all types, add IFC name attribute and then set the type to zone.
I am not sure if I understand what you are trying here. You want to select multiple Zones with some kind of the same IFC tag? I have been told all IFC entities are created upon set Archicad Element Properties, which are through Archicad Classifications v 2.0 translated into correct IFC pSet entities. All IFC designations are for correct data exchange between disciplines. This is how I use Archicad. I don't set any IFC attributes manually.
The Name (Attribute) field gets populated with the same value you set for the Zone Number. Maybe you should try find&select for a Zone Number.

For some particular reason (lack of mapping implementation?) there is no option to map new custom values to IfcZone rooted attributes. The only way is what @Miha_M suggested you, meaning using the predefined mapping within Archicad, the same way there is a predefined mapping also for Type and Type Name (IFC Type Product). But the difference with the last one is that you are able to map custom values to any IfcBuildingElement subtype.
Yes, for a Zone Element Created in AC the Name Attribute is mapped to Zone Number so given that Name is unedited for the elements then you can search for Zone Number instead.
But what if it is edited or you want to search based on some other IFC property?
It is rather strange that IFC attributes/properties can't be added as criteria if the element type is set to Zone. Especially as it can be forced by adding the IFC attribute/property first (with element type set to all) and then change it to Zone.
Indeed. IfcZone is a subtype of IfcGroup and IfcSystem, and its main purpose is grouping IfcSpace (AC Zones or Revit Room or Revit MEP Zone, etc...etc...).
But that should not be a problem for mapping the Attribute name. Since all of them come from IfcRoot, they inherit the Name Attribute, therefore.... why should not be able to map a custom value to them? The same way we are doing to any occurrence of IfcBuildingElement or IfcDistributionElement.
