Although conventional three-dimensional CAD systems are useful for modeling the geometry of products, the support function for design itself is lacking on the systems. In the present paper, to achieve the concurrent working between the consideration of machine design and its geometrical modeling, an idea of the modeling based on design intention, that is named intention-driven modeling, is proposed. The concept is expressed through object-oriented expression of design knowledge. A prototype system is developed to demonstrate examples of top-down design and modeling of products from conceptual design stage. The system brings such benefit that the designer can concentrate the attention on the thinking for design.
