# ifc-properties
Property sets, quantities, templates and unit resolution as borrowed views
over `ifc-model`, with a permissive API for inspection and an exact,
release-bound API for rule engines. It never computes a shape measurement: an
authored quantity can be compared against a value the caller computed
elsewhere.
```bash
cargo add ifc-properties
```
The [`openbim-ifc`](https://crates.io/crates/openbim-ifc) facade also provides it behind its
`properties` feature.
