This package provides functionality for encoding and decoding data in ISO 10303-21 (STEP file) format. It is likely only useful as a base for higher-level packages that support particular STEP-based file formats such as IFC and the various STEP application protocols.
Please open a new issue if you run into a bug, if any documentation is missing/incorrect/confusing, or if there's a new feature that you would find useful. For general questions about using this package, feel free to send me (@ianmackenzie) a message on the Elm Slack.
