"""Links an object to a product via IfcRelAssignsToProduct

Typically used to associate a physical building element with a structural
|
||
|
|
analysis member (IfcStructuralSurfaceMember, IfcStructuralCurveMember) so
|
||
|
|
that analysis results can be traced back to the physical model.

|
|
:param relating_product: The IfcProduct that the object is assigned to,
|
||
|
|
typically an IfcStructuralMember.
|

|
|
:param related_object: The IfcObjectDefinition being assigned, typically
|
||
|
|
a physical building element such as an IfcWall or IfcSlab.

:return: The IfcRelAssignsToProduct relationship.
