Edits the attributes of an IfcRelSequence

For more information about the attributes and data types of an IfcRelSequence, consult the IFC documentation.

Parameters:

• rel_sequence (ifcopenshell.entity_instance) – The IfcRelSequence entity you want to edit

• attributes (dict, optional) – a dictionary of attribute names and values.

Returns:

None

Return type:

None

Example:

# Let's imagine we are creating a construction schedule. All tasks
# need to be part of a work schedule.
schedule = ifcopenshell.api.run("sequence.add_work_schedule", model, name="Construction Schedule A")

# Let's imagine a root construction task
construction = ifcopenshell.api.run("sequence.add_task", model,
    work_schedule=schedule, name="Construction", identification="C")

# Let's imagine we're building 2 zones, one after another.
zone1 = ifcopenshell.api.run("sequence.add_task", model,
    parent_task=construction, name="Zone 1", identification="C.1")
zone2 = ifcopenshell.api.run("sequence.add_task", model,
    parent_task=construction, name="Zone 2", identification="C.2")

# Zone 1 finishes, then zone 2 starts.
sequence = ifcopenshell.api.run("sequence.assign_sequence", model,
    relating_process=zone1, related_process=zone2)

# What if they both started at the same time?
ifcopenshell.api.run("sequence.edit_sequence", model,
    rel_sequence=sequence, attributes={"SequenceType": "START_START"})
