# 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.
```bash
cargo add ifc-cost
```
The [`openbim-ifc`](https://crates.io/crates/openbim-ifc) facade also provides it behind its
`cost` feature.
