8.18 IfcRepresentationResource
8.18.1 Schema definition
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:
- topological representation
- geometric shape representation
The geometric shape representation allows for
- multiple shape representations for the same product definition shape of a product
- separate shape representations for components or parts of the product definition shape by using shape aspects
