The IFC Project Manager (File > Interoperability > IFC) provides a hierarchical overview of the current project’s IFC model database. Each model element is listed with its IFC attributes and properties.
Most of these are inherited from import/export IFC standards set elsewhere (e.g. Type Mapping and Property Mapping presets of the project’s IFC Preview Translator.) However, you can edit values in IFC Project Manager for any specific element, and/or create custom IFC properties or Property sets as needed.
