Abstract

PURPOSE:To effectively use the storage area of a data base by storing the graphic information on a designated member in such a tate where only the reading of the graphic information is permitted with the correction/change inhibited respectively when the graphic information satisfies the prescribed conditions based on the retrieving result. CONSTITUTION:When a designer A needs the data 211 on other designers while producing a plan 210, an operator reproduces the data 211 to a control part 200. The data 211 are written in an area 212 where an uncorrectable state of the data can be recognized. Meanwhile the desired data to be corrected by the operator himself are written in a correctable area 210. Then a system displays the data written in both areas 210 and 212 and permits the designer A to perform a designing job in a state where the graphic of another designer is also displayed. Under such conditions, each designer decides based on each identifier added to the drawing data under designing whether the graphic data on other designers are written in the area 210 or 212 through the part 200.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a layout design support apparatus for supporting design of layout of members, and in particular, it is possible to edit while designating own design data and design data of another person together. A layout design support device.

[0002]

2. Description of the Related Art As a proposal using a computer to support layout design, for example, there is JP-A-63-168777. This technique is to set an arrangement rule and determine undecided parts according to the rule.

[0003]

By the way, when designing an automobile, for example, many designers are usually involved in the design. That is, one designer cannot design one car, and many engineers are
Design some parts and units respectively. In particular, a unit consists of multiple parts, and when different designers proceed in parallel with each other, these individual parts may spatially compete with other parts. Therefore, it is necessary to match the parts.

However, after the parts design is completed,
There is no point in designing with the aid of a computer to make these parts as prototypes, assemble them into a unit, and then match them. Therefore, when performing parallel design, conventionally, a designer duplicates the design data of another designer,
I opened it with my data file in my system, and performed matching operation while displaying the quantity data together.

For this reason, files that are not always necessary overflow in the storage device, and in extreme cases, it may not be possible to identify the files or the free space may be insufficient.

[0006]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to propose a layout design support device which does not cause a shortage of free space. The configuration of the present invention for achieving the above-mentioned object is a layout design support apparatus including a storage unit that stores the relationship between the graphic information of a member and the space occupied by the member, and the member and the member to be occupied by the member. Means for designating a space, means for retrieving graphic information of designated members,
When the graphic information of the specified member satisfies a predetermined condition as a result of the search, the graphic information is stored in a state in which the graphic information can only be read out and the modification cannot be changed. .

According to the support apparatus of the present invention, the graphic information is saved only when the predetermined condition is satisfied, that is, only when the information really needs to be saved.

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. In this embodiment, the layout design support device of the present invention is applied to the performance design of an automobile. FIG. 1 shows the configuration of the design support system of the embodiment.
In the figure, 100 is a database storage device, and a large capacity disk file device is usually used. A control unit 200 reads and manages a file. Reference numeral 400 is a display device for displaying a design drawing for layout design, and 500 is a keyboard or mouse for inputting data necessary for designing. The calculation unit 300 is a calculation unit that calculates whether or not competition occurs in component placement.

FIG. 2 shows a database file device 100.
Shows the data stored in. In the example of FIG. 2, in the file device 100, a database such as the standard parts database 101 and the variable parts database 102 that can be opened commonly by designers, a data file 103 that the designer A is working on, and a designer B are working. Inside data file 10
4 etc. are included.

FIG. 3 is a diagram showing a logical data structure of parts in the present design system. According to the figure, "unit" or "part" consists of multiple "figure groups",
Each "graphic group" consists of a plurality of "graphic elements". Figure 4
Shows what kind of parts the "part" called the steering device is made up of. In FIG. 4, the steering device 130 includes graphic groups 131, 132 and 133, and the graphic group 131 includes graphics 135 to 139.
The figures of the graphic groups 132 and 133 are not shown.

Real "units" or "parts" actually occupy space. Also in this system, information about how to occupy the space for the “unit” or the “component” (called occupied space information) is given in advance. As shown in FIG. 3, like the “unit” or the “part”, the “occupied space information” is given to each “graphic group” or “graphic element”.

The occupied space information is specified in the XYZ space.
That is, "parts", "figure groups", and "figure elements" are expressed in the minimum space that can be occupied respectively. In this system, this space adopts a rectangular parallelepiped as shown by the broken line in FIG. This is because the calculation is simple. When a logical structure as shown in FIG. 3 is given to a part or unit, a "graphic element" constituting the part is automatically determined from one part. That is, FIG.
As shown in FIG. 5, the azimuth is given to the body in the XYZ axes, and the arrangement position of the above-mentioned “steering device” 130 in absolute coordinates in FIG. 5 is given. "Steering device" 130
When the absolute placement positions of the graphic groups 131 to 133 are determined, the absolute placement positions of the graphic groups 131 to 133 in FIG. 5 are automatically determined. . Since the relative arrangement positions of the respective "graphic elements" in the individual graphic groups are previously determined, the absolute arrangement positions of those "graphic elements" are also automatically determined.

In order to form a "figure group" from "figure elements" 135 to 139 of FIG. 4 and further form an image of "parts", "between graphic elements" and between "figure elements" and "figure elements" Interference with is a problem. This interference portion is processed by the well-known "hidden line processing". One designer is one
It is not a problem just to design one part or one unit, but if the part or unit designed by that designer interferes with the unit or part of another designer, the other designer Data is required. This is because, as shown in FIG. 6, the drawing designed by oneself is influenced by the part or unit designed by another designer. This may require someone else's data file.

Generally, in a CAD system such as this system, a unit designed by a designer, that is, data corresponding to one drawing (part) is one processing unit of the system. These processing units are equal and independent of each other (FIG. 8). Therefore, the design system cannot handle a plurality of drawings at the same time. Therefore, when the designer A wants to combine the drawing of the designer B with the drawing he is currently designing, it is necessary to incorporate the data into his data (FIG. 9).

For this reason, as shown in FIG. 1, when the designer A needs data 211 of another designer while creating the design drawing 210, the operator controls the control unit 200. On the other hand, the design data 211 of another person is copied. The copy is written in an area (area 212 in the example of FIG. 1) that can be recognized as uncorrectable data. Further, the data that the user wants to correct is written in the correctable area (area 210 in the example of FIG. 1). The system displays the data written in both areas and prompts designer A to
The design of the figure is allowed at the same time.

In this system, each designer, for each drawing data under design, in the example of FIG. 3, for each "part", "graphic group", "graphic element", An identifier indicating whether or not another person's change is allowed is attached. In FIG. 1, the control unit 200 determines, based on the above identifier, whether the control unit writes the graphic data of another person in the storage area in which the data can be modified or in the non-correctable area.

Next, a control procedure in the case where one designer calls the graphic data of another person (the steering device in FIG. 4) together with the graphic data of his / her own and edits his / her graphic data will be shown. In step S100, a space in which the figure of another person is to be generated is designated. This designation is, as shown in FIG. 5, the identifier of the graphic to be generated (in the example of FIG. 4, designated by the identifier given to the "steering device"), the azimuth of the graphic, and its absolute position. Is specified by the operator. Step S
At 102, the control unit 200 searches for a component existing in the space using the link relationship shown in FIG. As described above, since the designer of another person has marked the figure data of FIG. 4 as “uncorrectable”, step S10 is performed.
In 4, the retrieved data is recognized as "reference data". This other person's graphic data is transferred and copied to the uncorrectable area (area 212 in the example of FIG. 1).

In step S108, the graphic data file currently being worked on is opened and displayed on the CRT device. In step S110, the graphic data accumulated in the area 212 is opened and displayed on the CRT device. Thus, the figure data of one's own and the figure data of another person are combined into C
It is displayed on the RT device. Step S112
In step S116, editing of the displayed graphic is permitted. That is, in step S112, the operator inputs a correction instruction for the graphic data. Step S11
At 4, it is determined whether the object of the correction instruction is for the graphic data of oneself or the graphic data of another person. If it is for one's own graphic data, the requested processing is executed in step S116. On the other hand, if the request is for another person's graphic data, the request is ignored after being issued a warning.

When the work is completed, the graphic data of its own is saved in step S120, and the graphic data (copy data) referred to in step S122 is erased. The present invention can be variously modified without departing from the spirit thereof. For example, in the above embodiment, the automobile design is described as an example, but the present invention is not limited to this. In addition, in the above-described embodiment, the operator has provided information as to whether or not the correction is impossible, but the following may be performed. That is, in the system, a password and a user code are set, and if the password matches, it can be referred to. Further, for a user whose password is the same, whether it can be modified or not can be preset for each designer according to the user code.
