Need Assistance in Retrieving Parent GUIDs for IfcSpatialElement Entities in IFC4 File Parsing Script

[ashi7upt]

I am working on a script to assign parent GroupIDs to various IFC entities within an IFC4 file. I have made progress in assigning GroupIDs to the "IfcProject" subclass. However, I'm encountering difficulties when trying to obtain the parent GUIDs for "IfcSpatialElement" entities.

Here's a simplified version of my current code:

def build_ifc_relationship_map(ifc_file):
rel_map = {}
for rel in ifc_file.by_type("IfcRelationship"):
if hasattr(rel, "RelatedObjects") and hasattr(rel, "RelatingObject"):
parent = rel.RelatingObject
children = rel.RelatedObjects
for child in children:
rel_map[child] = parent
return rel_map
My question is: How can I modify this code to successfully retrieve the parent GUIDs for "IfcSpatialElement" entities? I've been able to obtain the parent GroupID for the "IfcProject" subclass, but I'm unsure about the approach to retrieve the parent GUIDs for "IfcSpatialElement" entities. Any guidance or suggestions on how to achieve this would be greatly appreciated.

Thank you in advance for your assistance!

for element in ifc_file.by_type("IfcSpatialElement"):
    parent = ifcopenshell.util.element.get_aggregate(element)
    print(parent.GlobalId)

Thank you but this code gives you the Groupid till IFCspace I also need parent Groupids for wall and windows

Do you mean you want to know the GlobalId of the spatial element that an object (e.g. a wall/ window) is in?

for element in ifc_file.by_type("IfcWall"):
    parent = ifcopenshell.util.element.get_container(element)
    print(parent.GlobalId)

[ashi7upt]

yes, I want to know these but they are not coming.

[Moult]

I just gave you the code that does what you're after (the get_container function).

thank you
