Abstract: A generic, integrated, parametric, automated product configuration system for parametric configuration of products such as offices on a building space plan. The system can produce bills of materials, costings and manufacturing drawings in real-time at the request of a user as the user specifies and configures the product components and parameters values. The system provides for real time three-dimensional visualization and editing of the product as it is configured. It also includes a rule engine for validating the product and automatically incorporating missing necessary components in a configuration in real-time as the user configures a product.
