“…In case of volumetric entity based techniques, the features are simplified by operating on volumetric entities from the model. The major techniques reported under this category are effective volume [Lee05a,Choi02], cellular representation [Lee04,Lim04], and voxel [He95,Andu02] based approaches. In the explicit feature representation based techniques, the feature information and semantics is explicitly extracted from CAD model or is present in the model in addition to geometric and topological data.…”

“…The entities are selected for removal based on predefined error metrics that evaluate the geometric impact of their removal. One of the reported error metrics used is quadric error [Garl97,Lee04]. Using the fact, that each vertex is an intersection of several planes, the quadric matrix Q (a 4 x 4 symmetric matrix) is defined for very vertex by aggregating the coefficients of equation of the planes in a way such that the quadric error (e) associated with the given vertex…”

“…The decimation approaches were originally introduced for obtaining multi-resolution models by simplifying the entire model at a time. Recent techniques involve selective simplification of surface artifacts using the same approach but limiting the simplification process in the region of interest [Lee04].…”

“…Lee et al present a method to generate progressive solid models (PSM) from feature based models using a cellular topology-based approach [Lee04]. Here cellular topology is used for generating the PSM and then surface entity based operators are developed to simplify the model.…”

Automated CAD model simplification plays an important role in effectively utilizing physicsbased simulation during the product realization process. Currently a rich body of literature exists that describe many successful techniques for fully-automatic or semi-automatic simplification of CAD models for a wide variety of applications. The purpose of this paper is to compile a list of the techniques that are relevant for physics-based simulations problems and to characterize them based on their attributes. We have classified them into the following four categories: techniques based on surface entity based operators, volume entity based operators, explicit feature based operators, and dimension reduction operators. This paper also presents the necessary background information in the CAD model representation to assist the new readers. We conclude the paper by outlining open research directions in this field.

“…However, at present, the cellular topology has only been applied to 3D features. The cellular topology is also used for collaborative design (Wu and Sarma 2001;Lee et al 2004) and efficient feature recognition (Woo 2003).…”

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 art, this paper reviews emerging concurrent and collaborative engineering approaches and emphasizes on the integration of different application systems across product life cycle management (PLM) stages. It is revealed that checking product information validity is difficult for the current computer-aided systems because engineering intent is at best partially represented in product models. It is also not easy to maintain the consistency among related product models because information associations are not established. The purpose of this review is to identify and analyze research issues with respect to information integration and sharing for future concurrent and collaborative engineering. A new paradigm of research from the angle of feature unification and association for product modeling and manufacturing is subsequently proposed.Keywords Concurrent and collaborative engineering · Feature-based design and manufacturing · Product life cycle modeling · Information validity and consistency
