Definition of the IAI: This schema defines the representation of shape and topology as important definitional properties for products defined within the IFC Object Model. The representations characterize certain properties of a product, and any product can be defined by zero, one, or many of those properties. The schema defines two ways to represent definitional properties of products:

The geometric shape representation allows for

The following parts of ISO10303, STEP, had been reviewed to provide input into the specification of the representation resource for the IFC Object Model:

Please note, that the above listed resources which are defined within Integrated Resources of STEP had been interpreted to fit into the IFC architecture.
