Description

A method for managing design information in CAD system

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to computer-related technologies, and relates to a method for managing design information in a computer-aided design (CAD) system (hereinafter referred to as a 'CAD system').

Product design is a big part of the manufacturer's product development process. The creation of design drawings is the final step in the product design process, ultimately aimed at adopting them as originals.

Typically, when a design drawing is completed, it goes through a rigorous inspection and approval process, and only drawings that have passed the approval can be assigned a unique code and applied to the production of the product. This is the final drawing applied to the Enterprise Resource Planning system-a computerized system that manages accounting, materials, production, inspection, etc.-and it is a very important document that provides all the information about product design. For reference, even if a design or material needs to be corrected for the product in progress, the original drawing is not modified, but after the designer's corrective work, the inspection and approval process is performed again. After that, a new original code with a unique code will be created. At this time, the newly created originality is recorded with the modifications.

On the other hand, although some drawings are still being performed manually, most of them have been replaced by a CAD system, and the CAD system is also moving from a 2D CAD system to a 3D CAD system. In addition, the use of CAD systems opens the way for integrated computational management of drawing data in conjunction with ERP systems. On the other hand, a single product consists of a large number of components. Should be. When designing a drawing using a two-dimensional CAD system, since each drawing exists as a separate file, even if the data center is constructed by linking the ERP system and the CAD system as described above, the file management cannot be moved beyond the simple file management level. It was. In other words, it was difficult to efficiently manage design information. On the other hand, since the 3D CAD system is organized in the same hierarchical structure (tree structure) as each part drawing data is assembled with the product, it is more convenient to manage design information relatively than the 2D CAD system. .

However, there has been no practical sharing of design information between CAD and ERP systems, regardless of whether it is a 2D CAD system or a 3D CAD system. There is a heading to record the design information such as the scale, the relationship number, product name, color, and material. There is no specific format for the heading, and the appropriate form is used for each company. The drawing author keeps the format of the heading as a drawing file, and then displays the file on the CAD screen before drawing. Enter information about the item. Thus, the heading is included as part of the drawing in the drawing file. As such a heading is included in the drawing, the design file for the item must be opened or visually confirmed through the printed drawing. That is, the database of design information was not made.

In addition, in order to use such design information in other departments (e.g., production department, material department, etc.), it was cumbersome to re-enter the design information displayed in the title through a computer connected to the ERP system. Management of design information is not efficient, such as an input error may occur.

The present invention proposed to solve the problems of the prior art as described above is to provide a design information management method in a computer-aided design system that enables the database of the design information.

In addition, an object of the present invention is to provide a method for managing design information in a computer-aided design system that enables more efficient management by sharing design information of a three-dimensional CAD system with an ERP system.

In order to achieve the above technical problem, the present invention provides a method for managing design information in a computer-aided design system, comprising: a first step of receiving a design information input module execution command from a user; A second step of opening, a third step of displaying a current design information input state of the drawing file in the design information input module, a fourth step of updating a heading of the drawing file according to newly input or modified design information, and an update And a sixth step of storing design information of the drawing file in a separate file format and a sixth step of storing the updated drawing file.

Hereinafter, preferred embodiments of the present invention will be introduced in order to enable those skilled in the art to more easily carry out the present invention.

1 is a diagram illustrating a network environment to which the present invention is applied, and a drawing system including a file server 10 and a plurality of designer terminals 11 connected thereto, a data server 12, and a kendo / approval And a kendo / approval system consisting of a temporary storage 13, a calibrator terminal 14 connected thereto, and an approver terminal 15.

Each designer terminal 11 supports individual drawing creation and transmits the created drawing file to the file server 10. The file server 10 supporting the drawing creation system receives drawing files from each designer's terminal 11, collects them, transmits the collected files to the temporary storage for kendo / approval 13, and checks the designer's terminal. When requested by (11), raw data is copied from the data server 12 and provided to each designer terminal 11 (check out).

The kendo / approval temporary storage 13 is a kendo terminal 14 and the approver terminal which are temporarily stored in the drawing file transmitted from the drawing system to the kendo terminal 14 and the approver terminal 15 for kendo and approval. Transfer the data according to the request of (15), and save the drawing data to be registered as original data to the data server 12 after the approval.

On the other hand, the data server 12 stores the raw data, and provides the raw data when a request for reading or copying is made from the ERP system 16 or the drawing production system.

2 is a flowchart illustrating a process of inputting / modifying design information according to an embodiment of the present invention. It is assumed that a drawing is created and stored as a drawing file.

First, if there is a command for executing a design information input program of a designer, that is, a user (200), the design information input program checks whether a CAD program is running (202), and automatically executes a drawing file open menu (206) if it is running. If the CAD program is not running, the design information input program executes the CAD program (204) and executes a drawing file open menu (206).

After the drawing file open menu is executed as described above, when a specific drawing file selection command for inputting design information is received from a designer, that is, a user, the design information input program executes file opening (208).

When the corresponding drawing file is opened, the design information input program displays the current design information input state (210). At this time, the already input design information (item) indicates the state that can not be input again.

Subsequently, an input / modification design information of the design information is received from the designer, ie, the user (212). At this time, if the designer who wants to modify the design information presses the modify button of the corresponding item, the content of the corresponding item is changed from the non-input state to the inputable state.

If all input / modification is completed and there is a designer's input command, the design information input program records the design information in the heading of the corresponding drawing file and stores the design information in a separate form (text file, spreadsheet file, user property file, database file). Etc.) (214).

Thereafter, the drawing file updated with the design information is stored.

If the design information is recorded in the heading of the drawing file through the design information input process as described above, the drawing file can be searched later, thereby making the database of the design information. In addition, as the database of design information becomes possible, there is no need to re-input and manage design information separately in an ERP system.

3A is an exemplary diagram of a design information recording module for implementing an embodiment of the present invention of FIG. 2, and FIG. 3B is a process of inputting / modifying design information items through the design information recording module of FIG. 3A. As an exemplary diagram for describing the present invention, it is understood that an item which is blurred such as color and material indicates an uninputable state as already inputted information, and heat treatment, surface treatment, relational drawing, etc. are not yet input.

In addition, a correction button is provided for each item, and as shown in FIG. 3B, when the correction button is clicked, the corresponding item becomes an input state. Meanwhile, as illustrated in FIGS. 3A and 3B, the design information input program includes a design information search function.

Meanwhile, FIG. 4 is a diagram illustrating a result of recording design information according to an exemplary embodiment of the present invention, and it can be seen that the content shown in FIG. 3 is recorded in a title of a drawing file.

5 is a process flow diagram for sharing design information of a CAD system with an ERP system according to another embodiment of the present invention, which assumes the use of a three-dimensional CAD system.

First, the design information input program opens the main assembly file of the 3D CAD system and reads configuration information (tree information) and drawing information of all lower drawing files (500). At this time, using the design information input through the same process as the embodiment of the present invention described above.

Next, the read configuration information and design information are stored in a general file format (eg, a text file, a spreadsheet file, a database file, etc.) according to a predetermined rule (502).

Next, the stored file is converted into a form suitable for a bill of material (BOM) system in the ERP system and registered (504).

The above process can be enabled because the design information is recorded in the drawing file through the design information input process as in the above embodiment, thereby sharing the design information of the 3D CAD system with the ERP system. Management can be enabled.

On the other hand, the above process is performed when the drawings are approved and moved to the data server, and when the design of some parts used in the product is not made in the 3D CAD system but in another system, it is immediately used in the ERP system. Because it cannot be displayed, it can be displayed and modified in the BOM system in the ERP system and registered in the BOM system when the 3D CAD file is moved to the data server.

6 is a view illustrating a processing flow for synchronizing file names according to another embodiment of the present invention, which also assumes the use of a three-dimensional CAD system.

First, when the designer selects the main assembly file through the design information input program (600), the design information input program is selected from one subassembly file selected from the subassembly files included in the main assembly file and subordinate to the subassembly file. One part file selected from the part files is opened (602). At this time, the main assembly file and the subassembly file are not executed (displayed). This is to reduce the system load because the file size of the assembly file is very large.

Next, the drawing file associated with the corresponding part file is searched (604). In this case, a method of searching for information of the drawing file connected to the name of the part file included in the drawing among the design information of the drawing file is used. That is, it uses the design information input through the same process as the embodiment of the present invention described above.

Subsequently, according to the changed names of the part file and the drawing file input from the user, the name of the corresponding part file and the drawing file connected thereto is changed (606).

Next, an external reference name in the drawing file associated with the corresponding part file is changed (608). Here, the external reference is information representing the path and name of the part file included in the drawing, and if the name of the part file is changed but the information is not changed, it will cause an error. At this time, it is preferable not to execute (display) the drawing file in order to reduce the load on the system.

Subsequently, the external reference name in the parent assembly file (including the main assembly file and the subassembly file) of the corresponding part file is changed (610). This also has the same meaning as mentioned in the previous step 608, and it is preferable not to execute (display) the assembly file in order to reduce the load on the system.

Subsequently, the part file is closed (612).

Next, it is checked if there are more part files not opened in the corresponding subassembly file (614), and if there are more check results, the process returns to step 602 to close the part file for the next part file (612). Do until.

On the other hand, if there are no further unopened part files in the subassembly file as a result of the check, it is checked whether there are more unassembled subassembly files (615), and if there are more subassembly files, the next subassembly and its subparts are checked. File open step 602 to file close step 612 are performed on the file.

On the other hand, if there is no further subassembly file as a result of the check, that is, the name change of all the part files in the selected main assembly file is finished, the process ends.

The above process can be possible because the design information is recorded in the drawing file through the design information input process as in the above embodiment, and the file name can be easily synchronized in the 3D CAD system. Discomfort on the stomach can be eliminated.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be apparent to those of ordinary knowledge.

For example, in the above-described embodiment, the present invention has been described based on a three-dimensional CAD system. However, the design information input process of the present invention can be applied to a two-dimensional CAD system.

The present invention described above has the effect of enabling the database of design information to manage the design information more systematically and efficiently. In particular, when the present invention is applied to a three-dimensional CAD system, the design information of the three-dimensional CAD system can be shared with the ERP system, and the file names can be easily synchronized, thereby reducing the administrative inconvenience. Can be.
