Edits the attributes of an IfcLagTime
For more information about the attributes and data types of an IfcLagTime, consult the IFC documentation.
- Parameters:
lag_time (ifcopenshell.entity_instance) – The IfcLagTime 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 doing a typically formwork, reinforcement, # pour sequence. Let's start with the formwork. It'll take us 2 # days. formwork = ifcopenshell.api.run("sequence.add_task", model, parent_task=construction, name="Formwork", identification="C.1") time = ifcopenshell.api.run("sequence.add_task_time", model, task=formwork) ifcopenshell.api.run("sequence.edit_task_time", model, task_time=time, attributes={"ScheduleStart": "2000-01-01", "ScheduleDuration": "P2D"}) # Now let's do the reinforcement. It'll take us another 2 days. reinforcement = ifcopenshell.api.run("sequence.add_task", model, parent_task=construction, name="Reinforcement", identification="C.2") time = ifcopenshell.api.run("sequence.add_task_time", model, task=reinforcement) ifcopenshell.api.run("sequence.edit_task_time", model, task_time=time, attributes={"ScheduleStart": "2000-01-01", "ScheduleDuration": "P2D"}) # Now let's say the formwork must finish before the reinforcement # can start. This is a typical finish to start relationship (FS). sequence = ifcopenshell.api.run("sequence.assign_sequence", model, relating_process=formwork, related_process=reinforcement) # Now typically there would be no lag time between formwork and # reinforcement, but let's pretend that we had to allow 1 day gap # for whatever reason. lag = ifcopenshell.api.run("sequence.assign_lag_time", model, rel_sequence=sequence, lag_value="P1D") # Or, let's make it 2 days instead. ifcopenshell.api.run("sequence.edit_lag_time", model, lag_time=lag, attributes={"LagValue": "P2D"})
