"""Assigns an actor to an object
|
|
|
|
An actor may be assigned to objects which implies that the actor is
|
|
responsible for. This is most commonly used in facility management for
|
|
indicating the manufacturers, suppliers, and warrantors for product
|
|
types.
|
|
|
|
Here are a list of objects you may assign an actor to:
|
|
|
|
* IfcControl: Indicates project directives issued by the actor.
|
|
* IfcGroup: Indicates groups for which the actor is responsible.
|
|
* IfcProduct: Indicates products for which the actor is responsible.
|
|
* IfcProcess: Indicates processes for which the actor is responsible.
|
|
* IfcResource: Indicates resources for which the actor is responsible to
|
|
allocate, manage, or delegate. This is not the actor actually using
|
|
the resource or performing the work. For that type of actor, see
|
|
ifcopenshell.api.resource.assign_resource.
|
|
|
|
:param relating_actor: The IfcActor who is responsible for the object.
|
|
:param related_object: The object the actor is responsible for.
|
|
:return: The newly created IfcRelAssignsToActor relationship.
|
|
|
|
Example:
|
|
|
|
.. code:: python
|
|
|
|
# We need to procure and install 2 of this particular pump type in our facility.
|
|
pump_type = ifcopenshell.api.root.create_entity(model, ifc_class="IfcPumpType")

|
|
|
# Define who the manufacturer is
|
|

|
|
identification="PWP", name="Pumps With Power")
|
|
ifcopenshell.api.owner.add_role(model, assigned_object=manufacturer, role="MANUFACTURER")
|
|
|
|
# To help our facility manager, it's nice to provide contact details
|
|
# of the manufacturer so they know how to call when the pump breaks.
|
|
telecom = ifcopenshell.api.owner.add_address(model,
|
|
assigned_object=organisation, ifc_class="IfcTelecomAddress")

"ElectronicMailAddresses": ["contact@example.com"],
