class ifcopenshell.api.material.remove_profile.Usecase(file, profile=None)#

Removes a profile item from a profile set

Note that it is invalid to have zero items in a set, so you should leave at least one profile to ensure a valid IFC dataset.


profile (ifcopenshell.entity_instance.entity_instance) – The IfcMaterialProfile entity you want to remove
