|summary||enable multiple mapped items as a shape representation of regular patterns|
Elements having pattern like arrangement of components, such as a bolt / nail group, a group of reinforcement bars, etc. are best defined in terms of their geometry as multiple mapped items referring to the same representation map.
This implementer agreement makes a preference to export such multiple mapped items and requires the correct import of multiple mapped items. In addition it provides a guideline to implement it.
The following figure shows how multiple mapped items shall be implemented as the 'Body' shape representation of such elements, as e.g. an IfcFastener.
