Abstract:
1. A method of product modeling used in computer-aided-design to represent physical bodies or product design from geometric entities of multiple dimensionality and topology, said method comprising the steps of: defining by instantiation a geometric data entity, establishing at least one Topological View using said geometric data entity to represent a physical region of a physical body or a product model; defining a property for each of said Topological Views to represent a physical, functional or a behavioral characteristic of said region of said physical body or said product model; and defining said Surface entity with properties; defining said Face entity with properties and EdgeLoop boundaries; defining said Solid entity with properties and OrientedClosedShell entity boundaries; defining said Surface entity properties, said Face entity properties and said Solid entity properties for each of said Topological Views to represent said physical, functional or behavioral characteristic or said region of said physical body or product model; and defining an overlapping of at least two EdgeLoop boundaries sharing said Surface entity.
