4.6.2.5 Property Sets for Profiles

The concept template Property Sets for Profiles describes how a material can be related to a single or multiple property sets. A property set contains a single or multiple properties. The data type of an individual property can be one of single, enumerated, value, table, reference or list value, and combination of property occurrences.

NOTE: An IfcProfileDef is not an IfcObject. For legacy reasons, this concept is listed under Object Definition. In future versions of the standard the various property set association mechanisms will likely be unified.

Property Sets applicable to this template will carry the IfcPropertySetTemplateTypeEnum "PSET_PROFILEDRIVEN".

The following diagram shows the generic classes and relationships used when applying this concept. In addition, concepts may have particular importance to common or standardised industry practices and scenarios. For these specific usage scenarios, the tables below shows a recommended list of general usage patterns that users may adopt.
