|
|
A cost item represents a single line item in a cost schedule. Cost items
|
|
may then be broken down into cost subitems.
|
|

|
Either `cost_schedule` or `cost_item` must be provided.

:param cost_schedule: If the cost item is to be added as a root or top
|
|
level cost item to a cost schedule, the IfcCostSchedule may be
|
|
specified. This is mutually exlclusive to the cost_item parameter.
|
|
:param cost_item: If the cost item is to be added as a subitem to an
|
|
existing cost item, the parent IfcCostItem may be specified. This is
|
|
mutually exclusive to the cost_schedule parameter.
