Abstract

PURPOSE:To make the changing of a display filter unnecessary by preparing a filter corresponding table from the display filter information of parts and a product on fitting the parts to the product, changing the display filter information automatically and displaying an element one by one. CONSTITUTION:When a command and data (a parts data name, etc.) are inputted from a graphic display device 4,an input processing part 1 analizes the data and transmits to a command executing part 2, and when it is the fitting command, judging whether the automatic changing of a display filter to a filter judging part 5 is possible or not is requested. The judging part 5 fetches the respective display filter information of product data stored in a field control part 8 and parts data for fitting data stored in a data base control part 7 from a control part 6. It is decided whether the one of the information is coincident with the display filter information of the any of the original product or not. When it is coincident, the control part 6 prepares a filter corresponding table. The display data after a display part 3 fits the parts is prepared and displays 4 them.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a shape design system, particularly a shape design system using CAD in various industrial fields such as electrical machinery, architecture, etc.

[Conventional technology]

In conventional shape design systems of this type, after a component is attached to a product, a designer instructs each element in the component one by one to change the display filter of each element.

Here, the display filter refers to a function that can control whether or not to display each element in each area of the graphic display device.

[Problem to be solved by the invention]

In the conventional shape design system described above, the designer manually changes the display filter of the attached part, so it takes a huge amount of time to change the filter of all the elements in the part. If the user of the component and the designer are different, there is a drawback that the display filter information of the component must be investigated.

[Means to solve the problem]

The shape design system of the present invention comprises an input processing unit that receives and analyzes commands or data when designing the shape of a product, a command execution unit that executes the input commands, and a graphic display device that displays the executed results. a display unit that performs display processing on the graphic display device; a database management unit that stores product data that is information about the entire product and parts data that is information about the parts that make up the product; and the graphic display. A workshop management section that stores the product data of the product that is displayed on the device and is the object of design; a filter management section that stores display filter information for one product part; and a request from the command execution section. and a filter judgment unit that compares the display filter information of the product and the parts to be installed and determines whether automatic change is possible, and creates a filter correspondence table if automatic change is possible according to the result of the judgment. and is stored in the filter management section.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention, in which an input processing section 1. Command execution section 21 display section 3, graphic display device 4. Filter judgment unit 5. Filter management section 6. It consists of a database management section 7 and a workplace management section 8.

The input processing unit 1 is a device that receives and analyzes commands and data input by the designer from the graphic display device 4, the command execution unit 2 is a device that executes the commands input by the designer, and the display unit 3 displays the executed results. This is a device that creates data to be displayed on the graphic display device 4.

When receiving a request from the command execution unit 2, the filter determination unit 5 compares the display filter information of the part and the display filter information of the product, and determines whether rotational movement is performed in units of 90°, and the filter management unit 6 is a device that stores display filter information for nine product parts, the database management section 7 is a device that stores product data and component data, and the workshop management section 8 is a device that stores product data of the product currently being designed.

Here, the display filter information refers to the direction in which the product or component is viewed and the name of the display filter, as shown in FIG. 2(B). Furthermore, product data and parts data refer to data for displaying one part of a product on the graphic display device 4.

When a designer inputs commands (installation commands, etc.) and data (component data names, etc.) from the graphic display device 4, the input processing section 1 receives and analyzes these input data, and sends them to the command execution section 2. send.

If the attachment is a command, the command execution unit 2 requests the filter determination unit 5 to determine whether the display filter can be automatically changed.

Upon receiving this request, the filter determining unit 5 displays display filter information (display filter name and (direction of line of sight) is taken out from the filter management section 6.

Then, the installation is determined whether one of the display filter information of the later parts matches the display filter information of any of the original products. Determine whether rotational movement at will result in a possible position.

If the determination result is YES, the filter management unit 6 creates a filter correspondence table (change table from old filter name to new filter name). If the determination result is NO, no filter correspondence table is created.

Finally, the display unit 3 creates display data for the product after the parts are attached, and displays it on the graphic display device 4.

Further, when the designer inputs a command for handling the product again after installing the parts, the command is analyzed by the input processing section 1 and sent to the command execution section 2. and,
When retrieving product data from the database management section 7 or the workshop management section 8, the command execution section 2 requests the display section 3 to perform display processing while referring to the filter correspondence table stored in the filter management section 6. It is displayed on the graphic display device W4.

FIG. 2 shows basic display filter information that products and parts have. (A) shows 14 basic directions (6 directions in the orthographic view and 8 directions in the eye-to-eye view), and (B) shows the correspondence between the drawing name and the display filter name of the direction. This information is created simultaneously when a product or part is first defined. The designer can arbitrarily create directions other than the 14 basic directions and display filter names corresponding to the directions, but the 14 basic directions cannot be changed or deleted.

FIG. 3 is a diagram for explaining the operation of this embodiment in a case where the actual product and parts are dice using a wire frame. (A) and (B) are nine product parts being displayed in four areas of the graphic display device 4, and the parts in this example are 1/2 of the product.

(C) and (D) are correspondence tables between the names and display filter names for the areas in which the nine product parts of this example are being displayed. Product 1
In addition to this, there is also a correspondence table for the parts in 10 directions (left side view, rear view, bottom view, etc.) that are not displayed.

Display filters exist in areas 1 to 4, and there are elements whose display is erased by the display filters. For example, in area 1, the display filter F1
Elements other than those forming the number 1 are erased, and in area 3, elements other than those forming the number 2 are erased by the display filter F2.

(E) shows the product after the parts of (B) are attached to the product of (A). Since the installation is performed so that the right side view of the part matches the plan view of the product, a filter correspondence table can be created.

(F) is the created filter correspondence table.

After installing the parts, you can refer to this filter compatibility table when handling the product. For example, when displaying a part in area 1, unless you refer to the filter correspondence table, since area 1 is the display filter F1, elements other than those that make up the "1" part of the part will be deleted and displayed. Ru. (G) is a diagram displayed without referring to the filter correspondence table.

If you refer to the filter correspondence table, area 1 is display filter F1, and according to the correspondence table, it becomes display filter F3, and elements other than those that make up the "3" part of the part are deleted and are not displayed (E). It becomes like this.

〔Effect of the invention〕

As explained above, the present invention creates a filter correspondence table based on the display filter information of parts and products when attaching parts to a product, and automatically changes the display filter information. Eliminates the need to spend time specifying elements one by one and changing display filters.
This has the effect that parts created by others can be easily used.
