Abstract
One of the key problems in building a computer aided design system that supports the entire design process is the development of a suitable computational scheme that enables the representation and manipulation of product geometric information with an evolving degree of vagueness or precision from early to detail stages of the design process. This paper reports the initial results arising from our ongoing research into the solution to this problem. A scheme that integrates techniques of constraint handling, interval representation and geometric modelling is developed. It is used to facilitate the representation and manipulation of such information in geometric configuration design. It is shown that geometric constraints provide a `natural’ language for describing various types of geometric information used in design particularly in the early stages. This scheme provides a uniform representation for the types of vague and precise information used in our pilot study and unifies their processing. Further research is being undertaken to enhance its abilities in accommodating more complex situations and supporting evolving design towards its completion.
