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

NOTE  The definitions within this schema have been influenced or have been adapted from ISO 10303-41, ISO 10303-42, and ISO 10303-43.
