ifcopenshell.util.schema.get_fallback_schema(version: str) → str¶: fallback to the schema version we do have docs and mapping for, needed to support IFC versions like 4X3_RC1, 4X1 etc

ifcopenshell.util.schema.get_subtypes(entity)¶

ifcopenshell.util.schema.is_a(entity: ifcopenshell.entity_instance, ifc_class: str) → bool¶

ifcopenshell.util.schema.reassign_class(ifc_file: ifcopenshell.file, element: ifcopenshell.entity_instance, new_class: str) → ifcopenshell.entity_instance¶

Attempts to change the class (entity name) of element to new_class by removing element and recreating a similar instance of type new_class with the same id.

In certain cases it may affect the structure of inversely related instances: - Multiple occurrences of reassigned instance within the same aggregate

(such as start and end-point of polyline)

Occurrences of reassigned instance within an ordered aggregate (such as IfcRelNests)

It’s unlikely that this affects real-world usage of this function.
