Feature-based product modeling is the leading approach for the integrated representation of
engineering product data. On the one side, this approach has stimulated the development of …

Initially developed for geometric representation, feature modeling has been applied in
product design and manufacturing with great success. With the growth of computer-aided …

Traditional structural optimization, which identifies the best combination of geometrical
parameters to improve the product's performance and to save the material, is often carried …

Automated CAD model simplification plays an important role in effectively utilizing physics-
based simulation during the product realization process. Currently a rich body of literature …

This paper proposes a CAD/CAE integration method using a “common data model”(CDM)
containing all the required parametric information for both CAD modeling and CAE analysis …

A new taxonomy of issues related to CAD model quality is presented, which distinguishes
between explicit and procedural models. For each type of model, morphologic, syntactic …

With widely used concurrent and collaborative engineering technologies, the validity and
consistency of product information become important. In order to establish the state of the …

Data sets with a large numbers of nominal variables, including some with large number of
distinct values, are becoming increasingly common and need to be explored. Unfortunately …

With the advances in CAD technology, it has been increasingly convenient to model product
shapes digitally. For example, in a feature-based parametric CAD system, the product shape …

Abstract Computer-Aided Design (CAD) and Computer-Aided Engineering (CAE) are two of
the essential tools to design and develop new products. CAD systems help to design a new …
