IFC properties can be custom, that is, you can define your own name and value for them, or follow a preset schema defined by the IFC standard. These properties are defined in Property sets and are usually made available for the most common IFC types. For example, the Pset_BeamCommon property set is made to be attached to beams. Predefined property sets usually contains usual properties that the IFC schema has defined for a particular type. For example, the Pset_WallCommon, that should be attached to walls, contains properties that define if the wall is load-bearing or is exterior or interior.
