ifc-cost

Cost semantics as a borrowed view over the IFC model: cost schedules and items, cost values, quantities, nesting and roll-up, plus transaction-staged IFC4 cost authoring; quantities are authored in the model's declared release. The crate owns no data, so a file with cost data round-trips identically with or without it.

cargo add ifc-cost

The openbim-ifc facade also provides it behind its cost feature.
