[0012]

Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of an embodiment of a shape information creating system according to the present invention.

This system includes an input device 1 such as a keyboard and a mouse, and an output device 3 such as a display and a printing device.
And a shape creation method selection unit 11, a shape creation processing unit 12, a shape selection unit 13, a shape information storage unit 14, and a manufacturing information storage unit 1.
5, a shape creation determining unit 16 and a shape creation device 2 including a shape creation rule storage unit 17.

[0014] The shape information memory section 14, the shape ever created, and shape various shapes factors that are frequently used to create have been stored, needs a shape selecting unit 13
The shape can be selected and extracted, and the shape creation processing unit 12 can add it to the shape information being created. The shape information stored in the shape information storage unit 14 is in one-to-one correspondence with the shape information necessary for actually manufacturing and the manufacturing information storage unit 15 storing position information.

The shape creation determining section 16 determines whether the shape to be created from now on can be actually manufactured by referring to the shape creation rules stored in the shape creation rule storage section 17.

The shape creation processing unit 12 includes a shape information storage unit 1
The shape information added to the shape information of No. 4 and the corresponding
Information 2 having the information of the manufacturing information storage unit 15 at the same time
1 is created and displayed on the output device 3.

The shape information storage unit 14 stores shapes frequently used when forming shapes, and can freely change parametric shape information such as standard holes, notches, and apertures. It is registered as follows. Corresponding to the shape information storage unit 14, manufacturing information such as coordinates and an original shape required for actually creating each shape is registered in the manufacturing information storage unit 15 in advance.

The shape creation processing unit 12 includes a shape information storage unit 1
The shape information 21 having the shape information 4 and the information in the manufacturing information storage unit 15 at the same time is created, and this is displayed on the output device 3. The shape data can be switched by an operator's operation so that shape information or manufacturing information is displayed.

The shape creation device 2 includes a shape selection unit 13
The user can select the shape information from the shape information storage unit 14, extract it as needed, and add it to the shape information being created by the shape creation processing unit 12.

Next, the operation of this embodiment will be described. FIG. 2 is a flowchart of the operation of the shape creation device 2 referred to for explaining the shape information creation method of the present invention. When given a command to create a shape from the input device 1, the shape creation device 2 sorts the flow of the creation method according to the creation method specified by the shape creation method selection unit 11 (steps A1 and A2). That is, it is determined whether to select the shape to be created from the information registered in the shape information storage unit 14, and the method of creating the shape differs accordingly.

In the case of designation not depending on the method of creation by selecting a shape in the shape information section 14, the shape creation is newly performed by CAD.
(Step A3), the manufacturing information is not registered as a pair with the shape data, and the manufacturing information is individually created and added.

When the shape is created by the shape selection of the shape selection unit 13, the shape registered in the shape information storage unit 14 is displayed on the display (step A4). From the displayed shapes, a shape to be created is selected with a keyboard or a mouse (step A5), and the shape selection unit 13 reads shape information and manufacturing information from the shape information storage unit 14 (step A6, step A7).

Here, it is confirmed whether or not the shape to be created can be actually created. In this process, the shape creation determining unit 16 checks the shape and production rule information registered in the shape creation rule storage unit 17 to check whether the shape is actually manufacturable (step A).
8, step A9).

Here, if the result of confirming the manufacturability is good,
The shape creating unit 12 selects the target shape on the display.
Automatically create based on the laid shape . If manufacturability is not possible, the process ends without creating a shape (step A10).

The shape created by the shape creation processing unit 12 is registered in the shape information 21 and registered in the output device 3. Here, the created shape information is registered in the shape information storage unit 14 and the manufacturing information storage unit 15 in a form corresponding to the manufacturing information corresponding to the shape (step A12, step A).
13).

The CAD operator determines whether only the shape information or the manufacturing information is required, as necessary.
It can be displayed on a display or extracted as data.

As described above, according to the present invention, when a CAD operator creates a three-dimensional shape with three-dimensional CAD software,
It is possible to create a three-dimensional shape in which information necessary for linking to the CAM is included without being aware that M data is being created.

Further, by inputting a creation instruction from the input device 1, the shape creation device 2 displays the shape registered in the shape information storage unit 14.
When the three-dimensional shape is created, the three-dimensional shape is simultaneously stored in the manufacturing information storage unit 15 paired with the shape information storage unit 14.
A three-dimensional shape including the corresponding manufacturing information can be created.

Thus, the CAD operator can view the shape information and the manufacturing information on the output device 3 without newly creating the manufacturing information.

[0030]

As described above, the present invention has a manufacturing information storage section in which manufacturing information corresponding to a shape registered in a shape information storage section is stored. The manufacturing information required for manufacturing can be created at the same time, eliminating the need for the manufacturer to read the shape information when using the shape data and to incorporate the necessary manufacturing information, thereby reducing the burden on CAD operators and reducing manufacturing costs. This has the effect of improving the work efficiency of the worker.

Since information that can be actually manufactured is included, by inputting the shape conditions based on the shape information search, it is confirmed in advance whether or not the shape to be actually created can be manufactured. There is also an effect that can be performed.
