AUTOMATIC THREE-DIMENSIONAL SOLID MODELING SYSTEM

PROBLEM TO BE SOLVED: To accurately and easily produce a three-dimensional solid model of a product which is composed of a set of plural shape patterns. SOLUTION: The shape pattern 102, the name of the pattern 102, a dimensional parameter and a location parameter input list 101 of a product are read by an automatic modeling system 103. The automatic modeling device retrieves a shape pattern that agrees with the shape pattern name of the list 101, sets the dimensional parameter value and the location parameter value to a data file having the same shape as the shape pattern and outputs this pattern (103) as a three-dimensional solid model by using a CAD system. This procedure is repeated for all data portion on the list 101 so that the three-dimensional solid model, i.e., a set of a plurality of shape patterns is modeled and registered in a CAD solid model data base 104.
