- Parameters
task (ifcopenshell.entity_instance.entity_instance) – The task to add time data to.
is_recurring (bool) – Whether or not the time should recur.
- Returns
The newly created IfcTaskTime.
- Return type
Example:
# Let's imagine we are creating a construction schedule. schedule = ifcopenshell.api.run("sequence.add_work_schedule", model, name="Construction Schedule A") # Create a portion of a work breakdown structure. construction = ifcopenshell.api.run("sequence.add_task", model, work_schedule=schedule, name="Construction", identification="C") superstructure = ifcopenshell.api.run("sequence.add_task", model, parent_task=construction, name="Superstructure", identification="C3") task = ifcopenshell.api.run("sequence.add_task", model, parent_task=superstructure, name="Ground Floor FRP", identification="C3.1") # Add time data. Note that time data is blank by default. time = ifcopenshell.api.run("sequence.add_task_time", model, task=task) # Let's say our task starts on the first of January when everybody # is still drunk from the new years celebration, and lasts for 2 # days. Note we don't need to specify the end date, as that is # derived from the start plus the duration. In this simple example, # no calendar has been specified, so we are working 24/7. Yikes! ifcopenshell.api.run("sequence.edit_task_time", model, task_time=time, attributes={"ScheduleStart": "2000-01-01", "ScheduleDuration": "P2D"})
