CASE, K. and WAN HARUN, W.A., 1997. A representation of assembly and process planning knowledge for feature-based design. IN: Harrison, D.K.

The need for a product model which can support the modelling requirements of a broad range of
applications leads to the application of feature-based techniques. An important requirement in featurebased
design and manufacture is that a single feature representation should be capable of supporting a
number of different applications. Assembly and process planning are seen as two crucial applications
and a formal structure for their representation in a feature-based design system is presented. This
research described addresses two basic questions relating to the lack of a unified definition for features
and the problem of representing assemblies in a feature-based representation. A prototype system has
been implemented using object-oriented techniques which provide a natural method of adding
functionality to the geometric reasoning process of features and the complex relationships between the
parts that make up the assembly. The feature-based model has been implemented using the ACIS
object-oriented solid modeller kernel.
