Abstract

There are numerous discussions concerning feature modelling. Most of these studies concentrate on regular shaped object modelling. The objective of this paper is to extend feature-modelling coverage to include sculptured objects, so that feature technology is beneficial to modelling this class of objects. Feature modelling for a sculptured object consists of two basic elements features and modelling operations. Feature semantics are declared by means of constraints in a feature class specification. These constraints are instantiated by the modelling operations during the modelling session. A feature modeller for sculptured objects is designed to generate the feature model from these constraints. A validation mechanism is introduced in the modeller to maintain the semantics of the feature model.
