I have created a simple model with walls and windows and assigned them to IfcWall and IfcWindow respectively. The IFC file which I get on Export, doesn’t have any relationship between the IFCWALL and the IFCWINDOW, i.e, the wall should have an association to an opening void and a relationship established that a window fills the void. The things(properties) I wanna see in my IFC file, that are not currently present, are IFCMAPPEDITEM, IFCMAPPEDREPRESENTATION, IFCRELVOIDSELEMENT, IFCRELFILLSELEMENT, IFCWINDOWSTYLE etc.
So, when I view my IFC file in a tree view, there should be a hierarchy where the IfcWall has IfcWindow as a sub-node (like a parent-child relationship).
Also, to make the IFC file shorter, multiple walls should be consistent and be ordered as a group of the same product and the IfcWindowStyle should be associated to windows with common definitions.
I am using the default IFC2X3.xsd as my classification.
Has someone cracked a way to achieve this with Sketchup Export? Thanks.
