Embodiment Construction

[0025] Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an automatic three-dimensional model construction system of an embodiment of the present invention.

[0026] In FIG. 1 , the automatic three-dimensional model building system is configured with a computer 10 , a keyboard 12 , a mouse 14 , a hard disk 16 and a display device 18 .

[0027] The computer 10 as a processing device resource acquires product shape information on various product shapes from a hard disk (storage resource) 16 according to a program for constructing a three-dimensional model, and displays information based on the acquired product shape information on the screen of a display device 18. image. In this case, the keyboard 12 and the mouse 14 as input devices function as the shape selection means 20 and the input means 22 as shown in FIG. Information on product shape, such as basic dimensions. When the input device 22 inputs...

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 ...
