"""Add a new distribution system
|
|
|
|
A distribution system is a group of distribution elements, like ducts,
|
|
pipes, pumps, filters, fans, and so on that distribute a medium (air,
|
|
liquid, or electricity) throughout a facility. Systems may be
|
|
hierarchical, with larger systems composed of smaller subsystems.
|
|
|
|
:param ifc_class: The type of system, chosen from IfcDistributionSystem
|
|
for mechanical, electrical, communications, plumbing, fire, or
|
|
security systems. Alternatively you may choose IfcBuildingSystem for
|
|
specialised building facade systems or similar. For IFC2X3, choose
|
|
IfcSystem.
|
|
:return: The newly created IfcSystem.
|
|
|
|
Example:
|
|
|
|
.. code:: python
|
|
|
|
# A completely empty distribution system
|
|
system = ifcopenshell.api.system.add_system(model)
