- class ifcopenshell.api.sequence.unassign_sequence.Usecase(file, relating_process=None, related_process=None)#
Removes a sequence relationship between tasks
- Parameters
relating_process (ifcopenshell.entity_instance.entity_instance) – The previous / predecessor task.
related_process (ifcopenshell.entity_instance.entity_instance) – The next / successor task.
- 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. ifcopenshell.api.run("sequence.assign_sequence", model, relating_process=zone1, related_process=zone2) # Let's make them unrelated ifcopenshell.api.run("sequence.unassign_sequence", model, relating_process=zone1, related_process=zone2)
