Abstract: In various industries where original design details of the product are not available, any modification or development in the product becomes a challenging task. In such cases reverse engineering can be used to develop functional 3D CAD models of the existing products. These models are feature based and give us the flexibility to duplicate or modify the existing product and find out the alternative design solutions for the product development problem. This paper describes the use of 3D scanning, metrology and instrumentation to extract the design information from an existing model of cream separator to design` a modified model. The project was done in Separators (India) that is located in New Delhi. To prepare the 3D models, assemblies and drawings we have used CATIA program. As a result of the project we have observed that development of new products by modification in existing products using reverse engineering saves considerable time and reduces the cost of product.
