Description

A method of design information management in CAD sistem

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 undergoes a rigorous inspection and approval process, and only the drawing that has passed the approval can be given a unique code as a drawing to be applied to production of a product. Originality is the final drawing applied to the enterprise resource planning system (ERP system), which encompasses accounting, materials, production, inspection, etc., and is very important for providing all information about product design. Because it is data, it is strictly controlled so that it cannot be modified arbitrarily. For reference, if the design or material, etc. need to be modified for the product in progress, instead of modifying the originality, go through the revised work of the designer with the originality as the parent and then go through the inspection and approval process again. You will create a separate diagram with code.

On the other hand, although some drawings are still being performed manually, most of them have been replaced by a CAD system, and the CAD system is also moving from a 2D CAD system to a 3D CAD system.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 computerized management of drawing data in conjunction with ERP systems. On the other hand, a single product consists of a large number of components, each of which has to be drawn up separately. 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 each drawing data is organized in the same hierarchical structure (tree structure) as the state in which the product is assembled, it is more convenient to manage the design information relatively than the two-dimensional CAD system.

However, regardless of whether it is a 2D CAD system or a 3D CAD system, design information has not been substantially shared between the CAD system and the ERP system. Typically, at the bottom of the design drawing, there is a heading section for recording design information such as urban street, theme name, tolerance grade, angular tolerance, scale, relationship urban street, product name, color, material, and the like. There is no specific format for headings, and the appropriate format is used for each company. The drawing author saves the format of the heading part as a drawing file, and then displays the file on the CAD screen before drawing the drawing, and inputs information for each item on the CAD screen. Thus, the heading is to be included as part of the drawing in the drawing file. As the heading is included in the drawing, the design file for the item must be opened and the drawing must be 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.

Meanwhile, in the 3D CAD system, a main assembly file, a subassembly file, a part file, a drawing file, and the like form a tree structure. In the early stage of design, a unique number is not assigned for each drawing. This is because the type and number of parts required are not determined at the initial stage of design, so that each designer randomly names each drawing file. In this case, since there is no regularity in the name of the drawing file, a person other than the designer could not match the drawing file with the corresponding part, which was inconvenient for management. Therefore, once a unique number for each part is determined, the file names need to be synchronized.

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.

Another object of the present invention is to provide a method of managing design information in a computer-aided design system capable of easily synchronizing file names in a three-dimensional CAD system.

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 hardware environment (CAD system) to which the present invention is applied, a drawing system including a file server 10 and a plurality of designer terminals 11 connected thereto, a data server 12, It consists of a kendo / approval system consisting of a temporary folder 13 for kendo / approval, 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 the drawing files from each designer's terminal 11, collects them, transmits the collected files to the temporary folder 13 for kendo / approval (check-in), and 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 temporary folder 13 for the kendo / approval is a kendo terminal 14 and the approver terminal that are temporarily stored in a 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 there is a request for reading or copying from the ERP system 16 or the drawing system side (check out).

2 is a view illustrating a process of inputting and modifying drawing information (design information) using a drawing information input program according to an embodiment of the present invention. It is assumed that a drawing is created and stored as a drawing file.

First, the designer executes the drawing information input program (200). If there is an execution command of the drawing information input program, the drawing information input program checks whether the CAD program is running (202), and if so, executes the drawing file open menu automatically (206). If the CAD program is not running, the drawing information input program executes the CAD program (204), and executes the drawing file open menu (206).

When the drawing file open menu is executed as described above, the designer selects a specific drawing file to which the drawing information is to be input and executes file opening (208).

When the corresponding drawing file is executed, the drawing information input program displays the current drawing information input state (210). At this time, the already inputted drawing information (item) indicates an impossible input state so that re-input is impossible.

Subsequently, the designer inputs the drawing information into the drawing information input program and modifies the corresponding item when there is drawing information to be modified (212). At this time, if the designer who wants to modify the drawing 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.

When all the input / modification is completed and there is a designer's input command, the drawing information input program records the drawing information in the heading of the drawing file and converts the drawing information into a separate form (text file, spreadsheet file, user properties file, etc.). Store (214).

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

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

The accompanying drawings, FIG. 3A illustrates the drawing information recording module in the drawing information input program mentioned above, and it can be seen that items that appear blurred such as color and material indicate already impossible input as input information. , Surface treatments, relationship drawings, etc., have not been entered yet.

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 drawing information input program includes a drawing information search function.

Meanwhile, FIG. 4 is a diagram illustrating a result of recording drawing information using the drawing information input program, and it can be seen that the content shown in FIG. 3 is recorded in a title of a drawing file.

5 is a view illustrating a processing flow for sharing design information of a CAD system with an ERP system according to another exemplary embodiment of the present invention, which is based on the use of a three-dimensional CAD system.

First, the system opens a 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, the drawing information input through the same process as the embodiment of the present invention described above is used.

Next, the read configuration information and the drawing information are stored in a general file format (eg, a text file, a spreadsheet 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 drawing information is recorded in the drawing file through the drawing 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 a main assembly file (600), the system selects one subassembly file selected from the subassembly files included in the main assembly file and a part file selected from the part files below the subassembly file. Open (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 the name of the part file included in the drawing among drawing information of the drawing file is used. That is, the drawing information input through the same process as the embodiment of the present invention described above is used.

Subsequently, 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 made possible because the drawing information is recorded in the drawing file through the drawing 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 can be made 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 description has been based on the three-dimensional CAD system. However, the drawing information input process of the present invention can be applied to the two-dimensional CAD system.

The present invention described above has the effect of allowing the database of design information to be managed 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.
