Abstract
There is provided a three-dimensional model generation system which makes it possible to utilize a former edge of a fillet erased from a geometry as a result of generation of the fillet, as required. When a fillet is designated by an input device, a geometry-generating/editing section fetches a feature corresponding to the designated fillet, via a feature management section. When the feature is a fillet, a former edge data management section obtains former edge data associated with the fillet feature from three-dimensional data storage section, to generate three-dimensional display data. The geometry-generating/editing section utilizes the three-dimensional display data to display a former edge of the fillet on a display, for selection. Thus, the former edge can be dealt with in the same manner as normal edges, which makes it possible to define parameters with reference to the former edge, for a parametric entity function. Further, it is possible to project a former edge of a fillet when a three-dimensional geometry is projected onto a two-dimensional plane.
