Metamodel for The Development of Geometrical Modelling Languages

Abstract

Paper discusses a potential of the metamodelling technology to improve computer-based methods of geometrical modelling. The meta-metamodel for the development of the geometrical modelling languages is proposed. It is defined as a formal system, which consists of geometrical metatypes, grammar and operations. The grammar rules are expressed as logical formulas, setting constraints on the geometric structure of a model. Paper proposes an additional system of relations for constructing the grammatical rules of geometrical languages. It is shown that use of the metamodeling makes the process of a geometrical design more effective.
