I have a question concerning the spatial decomposition with IFC. In the schema it is stated: “an element can only be contained within a single spatial structure element”.
How do I handle Building separation wall in multi-family houses / terraced houses? They belong somehow to 2 different IfcBuilding/ IfcBuildingStorey.
Any idea how to adress that issue? Is there a correct solution? At the moment I’m thinking of 2 options:
- I can not decompose my 2 houses in 2 different IfcBuilding. I need to have only one.
- I have to choose where the wall belongs to and one IfcBuilding will have a missing wallelement.
I would be happy if anyone knows a correct solution here or if I am missing something in the schema.
