The geometric modelling system plays an important role in CAD for the mechanical engineering. This paper presents the general purposed conversational geometric modelling, HICAD which has been developed to confirm the integrated CAD. The HICAD is a generalized geometric model which includes three of the typical geometric modellings, i.e., the wire frame,(More)
