| Abstract | Traditional computer aided design (CAD) systems assume that the solids under design are homogeneous in material compositions. Recent studies have shown that solids made of heterogeneous materials (multiple materials, functionally graded materials etc.) prevail in some aspects in terms of mechanical, thermal or electrical performances. Most of the traditional CAD systems fail to represent, maintain and visualize such heterogeneous components, and there have been no commercial heterogeneous CAD modelers in the market. This paper proposes a new interactive CAD environment for heterogeneous object design, in which the geometry, topology and material information of a CAD model can be simultaneously manipulated. The functionalities of a heterogeneous CAD modeler are identified first, and a framework for heterogeneous object design is proposed. The issues of data representation, data maintenance (edition and update) and 3D visualizations are discussed. An interactive software package based on this framework—CAD4D is presented and detail examples are illustrated. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
