Publish IFC using IfcSpatialZone class instance

Hello,

I wonder why the class IfcSpatialZone appears in the IFC Schema when setting up the Property Mapping in IFC Translator, if you cannot generate any geometry and map it to that class using the Type Mapping setting.

https://standards.buildingsmart.org/IFC/RELEASE/IFC4/ADD1/HTML/schema/ifcproductextension/lexical/ifcspatialzone.htm

On the other hand, you can export any geometry to IfcSite using the Type Mapping, and this class is a subtype of the IfcSpatialStructure, sibling of IfcSpatialZone sharing the same SuperType IfcSpatialElement.

The advantage of using this Class IfcSpatialZone is that you can attach a geometry into an independent spatial structure, not following the hierarchy of IfcSite>IfcBuilding>IfcBuildingStorey. We have several situations in which we have to inform about such those spatial structures, i.e. safety volumes, urban planning constraints, etc...

As we know, IfcZone is just an assignment, therefore a group of IfcSpaces, but there is a lack of own geometry, just the addition of Archicad Zones geometry.

So, my wish is to be able to instantiate IfcSpatialZone when publishing using the MVD IFC4 Reference View from Graphisoft Archicad.

Kind regards,

David

Hello, Minh

I am currently also participating in the IfcSpatialZone Working Group of buildingSMART International, moderated by Gianluca Genova.

Probably someone from the WG already contacted Graphisoft in regards to this topic. Anyway, let us know which is the current state of this implementation from the GS side.

Kind regards,

David
