Abstract

To efficiently construct a three-dimensional model. A product is divided into two parts of a head portion and a neck portion. A head form 34 and a neck form 36 are selected as forms of a three-dimensional model. The basic dimensions of each part are inputted to calculate dimension values of each part, and a combination of a basic form and a cut part is selected in accordance with a table 38 . If it is necessary to change the basic form of the neck form 36 , the dimensions of a basic-form model 40 are changed to construct a model 42 . Furthermore, a cut part 48 is selected, and the model 42 is processed to construct a model 50 . Then, by combining a head-form model 52 and the neck-form model 50 , a three-dimensional model 54 of a bolt is constructed.

Description

technical field

[0001] The present invention relates to an automatic three-dimensional model building system, and in particular to an automatic three-dimensional model building system for building a product three-dimensional model preferably by means of a computer. Background technique

[0002] As a device for generating three-dimensional model data, there are conventionally known devices, such as shown in FIG. 6, which are provided with: an input device 1 for inputting data on a three-dimensional model; The data inputted by the input device 1 to automatically design the information required for the shape of the product; When constructing three-dimensional models for various products from shapes defined on a two-dimensional plane, structures using basic functions of CAD systems such as rotation and extrusion are employed. In this case, when constructing a model of a shape similar to a model shape defined on a two-dimensional plane, the model can be automatically created by ...
