In recent years, 3D-CAD system has been rapidly improved. However, the principal improvements are focused on the shape modeling and operativeness, so that it is still remained solved how to treat the design information and the intention generated within the design process. It is important for 3D CAD to become means of more widely used information transmission and to support the designer to detailed design with design information and intention which was considered in the conceptual design. In this paper, we discuss the integrated model of the geometric model and the design information. In order to support the detailed design phase, the transmission architecture of the design information and the intention is also proposed through typical examples when design changes
