merging building storey level and IFC relationships -Federating Models

[Alikhuder]

Hello,
I'm trying to federate multiple IFC files into one model using IfcOpenShell. I've reached the project hierarchy up to the building storey level following the discussion in [1]. However, I want to merge building storey level and IFC relationships. Can you further advice on this or provide me with an idea? Thanks in advance.

[1] #237

I'm using :
Python 3.7.6
Anaconda
Pycharm
ifcopenshell-v0.6.0

@Alikhuder you can modify the IfcPatch recipe in that script in #237 to look for things like IfcSpatialElement with the same name or GlobalId, or whatever rule you use to merge to, and try that?

Also, happy bug number 1,000!

@Moult thank you for the quick reply and happy bug number 1,000 :)
I'll try that and see if it works. Thank you

Hi again, @aothms @Moult I know my question might be simple, but I'm new to the ifcopenshell. Is there any way that I can merge two IFC files based on the relationship entities such as IfcRelAggregates and IfcRelContainedInSpatialStructure? For instance, if I extract the IfcRelContainedInSpatialStructure entity and then compare it to the same entity that exists in the other file based on the GUID and then keeps only one and saves it into another file. if yes, can you provide me with a simple example or link for similar ideas? Thank you in advance.
