4.8.1.10 Mapped Geometry

Elements may have a 'Mapped Geometry' representation that reuses the concept Product Type Shape at the corresponding product type, as defined by the concept Object Typing.

The representation identifier of the mapped geometry representation is any of the other valid geometric representation identifiers, such as 'Body', 'FootPrint', or 'Axis'.

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.
