An IfcProduct can be placed relative to a positioning element such as IfcAlignment, IfcGrid or IfcReferent.

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.
