ABSTRACT

In recent years, 3D-CAD systems have been rapidly improving. However, the principal improvements
are focused on shape modeling and operability, so that it is still remained to be solved how to handle
the design information and intention generated within the design process.

Our objective is to smoothly and broadly support the design process more by proposing an architecture
to handle the design information and intention from the upstream design stage to the downstream
process. Especially, it is important to analyze the design information which should be handled in the
upstream design stage and to transmit this information accurately up to the detailed design stage where
the geometries are decided. In this paper, the important information in the upstream design stage and
the framework to handle these kinds of information is discussed.

1. BACKGROUND AND OBJECTIVES

3D-CAD systems have been rapidly improving. However, the principal improvements have been
focused on geometric modeling and developing user-friendly operational improvements, while
neglecting improvements to the treatment of design information and the intention generated in the
design process. It is important for 3D CAD systems to become a means for delivering widely used
design information to support the designer to the detailed design with design information and intention
which was considered in the conceptual design phase [e.g. 1].
