FIAT Car Body Design Parametric Design Guide

By using this methodology, engineers can determine the framework of a new car body, respecting the company standards. The main benefit is the reduction in development time as a design modification process is optimized. In addition to the design history is recorded and the same parametric model can be reused for several vehicle projects. FIAT Auto Elasis and began to test the parametric and associative (P / A) techniques at least 6 years ago [1], in order to create the archetype of all Fiat vehicles. Fiat is one of the first automotive company to test the P / A features in the development of a new car. The project’s objectives is to develop a new P / A design methodology in order to: • reduce the time of modification during the development of new car body; • parametric re-using the same model for future platforms. Recommended physical o logical elements of an object that an engineer can be used as geometric model definition component. Examples of features through the hole, slot, pocket, gutters and so on. Therefore, features can be seen as the sequence of geometric operations (building blocks) that have meaning for engineering product definition. The main benefits expected from this system is to optimize user productivity and reduction in the modeling of the modification time. CAR BODY DESIGN METHODS. This methodology is based on P / A CAD but also to the concept of archetypes. A basic pattern is a set of logical parameters and features of an object or system that can be used to build CAD models relative [5]. Component level is managed by technicians who have the responsibility to develop a relatively clear groups and blocks, with a specific archetype. The emphasis focuses on the management company due to modifications affect product development time and, therefore, the processes related to the flexibility of styling modifications, continuous improvement and implementation of new concepts. That way, each modification can be implemented in a short time, respecting all product and process
