# ifc-systems
Distribution systems as borrowed views over `ifc-model`: systems and zones,
ports and their attachment to elements, the port connection graph with
cycle-safe traversal, flow roles and direction, and the buildings and
facilities a system serves, plus authoring for systems, ports and their
relationships.
```bash
cargo add ifc-systems
```
The [`openbim-ifc`](https://crates.io/crates/openbim-ifc) facade also provides it behind its
`systems` feature.
