METHOD FOR MAKING 2-DIMENSION DRAWINGS [0002]

The present invention relates to a two-dimensional drawing method, and more particularly, to a two-dimensional drawing method in which a multi-dimensional drawing is made two-dimensional and a title column, a color, a part list design specification, And more particularly, to a two-dimensional drawing method for improving the quality of a mass-produced product and improving the reliability of the product by providing criteria for history management of the product such as design changes.

CAD, widely used to create 3D models, is an abbreviation of computer aided design, which refers to a computer-aided design program.

CAD is not designed to draw the drawings one by one on the drawing board, but it is designed to synthesize the information of the database on the screen and synthesize it, so that it is possible to make the work harder and faster.

And the contents designed by CAD are directly connected to CAM (Computer Aided Manufacturing), and CAM gives precise work operation instruction to NC machine tool, and it manages manufacturing process such as production, processing, assembly, And the precision of the product.

CAD is a 3D (3-Dimensional) CAD program that models objects from a 2D (2-Dimensional) plane on a 2D plane to a given command in a programmed three-dimensional space where the actual product appears to exist. The 3D CAD program not only reproduces the three-dimensional shape perfectly on the computer screen, but also automatically calculates the physical properties such as the surface area, volume, weight, and strength of the object, and designs it in a suitable form.

Furthermore, CAD software is growing at a remarkable rate from 3D CAD programs to '4D' simulations by adding 'time' variables.

These CADs can be used in various fields depending on the field of use. CAD programs (Auto CAD, IntelliCAD, FelixACD, UniCAD) which can be used regardless of the general purpose CAD area and can be adjusted by the user, CAD programs (Auto CAD MAP, OpenGIS), CNS / FMS roads, etc. designed for the CAD programs (OrCAD, PACD) and GIS geographic map making designed for designing 9Auto CAD ADT, (MDT, Solid Works, CADKEY, CADRA) for MDA machine-related design, and CAD programs (Softdesk Civil / Survay, Dagle Point and Quick-Road)

Such a CAD could display or convert a two-dimensional CAD drawing on a screen as a three-dimensional CAD drawing for each program, but there was no way to display a three-dimensional or more multidimensional model again in two dimensions. Some 3D models have been converted into two-dimensional models. However, there has been a problem that it takes a long time to correct the TEXT in the conversion or an error occurs, and the design history must be separately described.

As shown in FIGS. 1 to 10, a two-dimensional drawing method, which is a preferred embodiment of the present invention, includes a two-dimensional drawing creating step S1 for creating a triangle view, a color creating step S2, The design specification modification step S5, the design specification fish step S5, the drawing number generation step S7, the BOM component construction diagram creation step S7, (S8).

It is preferable that the two-dimensional working drawing creation step S1, the color creation step S2 and the drawing number generation step S7 are sequentially performed in one process. It is preferable that the title column generation step S3, the part list generation step S4, and the design specification generation step S6 are also sequentially performed in one process. These two processes must be performed in order, and the other steps may be performed in any order after the two-dimensional drawing drawing step S1. The design specification generation step (S6) may be performed at any time after the two-dimensional work drawing generation step (S1) regardless of the order of the other processes.

In the step of creating a 2D drawing (S1), a triangle view is a three-dimensional model for expanding a three-dimensional model on a two-dimensional plane, and is based on a trigonometry, which is a two-dimensional drawing system standard of the Republic of Korea. . If you click the '2D 3D Drawing Conversion' command icon on the main menu of the CAD program, a submenu window is created. A submenu window is provided with a selection unit for selecting a view scale, a selection unit for selecting a view generation method (one angle method or triangle method), and a selection unit for selecting a front view reference plane. The two-dimensional drawing drawing step S1 includes a step of selecting a drawing view scale by a user, a step of selecting a projection method, and a step of selecting a plane to show a desired surface in a front view. The two-dimensional working drawing generation step S1 automatically generates the working drawing 1 by selecting at least one of these steps. A front view, a side view, and a plan view can be made through an operation of selecting each of the selectors, which is displayed as a two-dimensional drawing on the practical drawing 1 as shown in Fig.

Next, the color creation step S2 is as follows. As shown in FIG. 3, in order to determine the position where each part is mounted on the vehicle, the car OEM 2 has a center of the front wheel or a center of the engine as the origin, . The unique TLH phase display, text position, etc. for each automobile OEM can be selected as an option in the submenu window created by clicking on the 'Create color automatically' icon.

As shown in Fig. 4, the title column is an outline of a kind of outline in a two-dimensional work drawing, and is an item for displaying the parts face, the work date, the worker, the reviewer, the approver, and the like. There are practical drawings for every 30,000 automotive parts, and a title column (3) must be created in each drawing.

In the title column creation step S3, a sub menu window corresponding to the creation of the title column is created when the user clicks the 'Create title column auto' icon. In the displayed submenu window, the user can modify the part name, date, and the like. It is desirable that the text that is always used is already written, and if the user desires, the previously written text can be also modified. When the modification is completed, the title column (3) is shown at the bottom right of the practical drawing (1).

As shown in FIG. 5, part list 4 describes the parts list of the product in the actual drawing. The intrinsic goal of drawing a two-dimensional drawing is for assembly, and the detailed parts constituting each assembly part are listed in a tree form, and a part list (= parts list) defined by a tree structure in a three- Should be written on the lower side. When the user clicks on the 'auto-generate part list' icon, a corresponding sub-menu window is displayed, and a part list previously stored in a document such as Excel can be called up through the sub-menu window. When the user completes the selection, the content described in the imported document is shown as part list 4 on the practical drawing 1. That is, the part list generating step S4 includes a step of writing a parts list in a sub-menu window, which is a part list input window, and a step of storing parts list data in which parts list writing is completed. Further, when the parts list data is stored in a document such as Excel or the like before the step of writing the parts list, it may further include a loading step of loading previously stored parts list data.

If there is a design change after the design confirmation and approval, the design change history should be filled in the design history change field (5) in the practical drawing (1). In the design history change field (5), the change contents and date are written. As shown in FIG. 6, the design history change field generation step S5 is written in the actual design drawing 1 and stored in a separate design history change document when the change is described in the generated design history change field 5. This will be described in more detail as follows. When the user clicks the 'Change Design History' icon, the corresponding submenu window is displayed. In the submenu window, enter the change date and date in the design change history entry box and the change date entry field. When the completion button is then clicked, the content of the description is written in the practical drawing (1) and stored in a separate design history change document.

As shown in FIG. 7, the specification of the corresponding part or product is inputted in the drawing, and a part which is difficult to be expressed by numerical values or pictures is written as text in the design specification 6, and a cycle is generally entered. In the program sub-menu window, open the applet for the product selection, select the desired specification, and click the Run button to automatically enter the specifications such as the cycle.

As shown in FIG. 8, the intrinsic goal of drawing a two-dimensional drawing is for assembly, and gives a quotation 7, which is a leader line for indicating the position of each component required for a two-dimensional drawing as an assembly drawing. The drawing number generation step (S7) automatically writes the quotation number (7) in the practical drawing (1). The number 7 is composed of a pointing 7a and a leader 7b. When the user selects the number of payee and clicks the execute button, a plurality of payee 7 is automatically assigned to the payee's drawing 1. The user completes the input of the number 7 by performing the operation of dragging the end of the leader 7b of the inputted number 7 to the desired part position.

The above steps are carried out to complete the two-dimensional practical drawing (1) as shown in Fig.

After the practitioner completes the two-dimensional drawing for assembly, various reports need to be prepared for various data management. In this case, the BOM component configuration diagram generation step (S8) is additionally performed to automatically create the BOM component configuration diagram. For example, to create a part schematic, you need to perform a PowerPoint operation to capture the assembly diagram and create the table. This is a time-consuming, simple task that increases the designer's fatigue. In order to solve this problem, the BOM component configuration diagram generation step (S8) is performed to automatically generate the BOM component configuration diagram. The BOM component diagram shows the parts of the document, the part name and the design specification, etc. in the document, and the drawings, part names or design specifications of these parts are shown in the finished work You can automatically download the corresponding information from the drawing.

As described above, the two-dimensional drawing method according to the present invention automatically creates each drawing element described in a practical drawing while making a three-dimensional and multi-dimensional drawing into a two-dimensional drawing. It is an object of the present invention to construct a solution that minimizes excessive work time input and error occurrence due to manual operation through such automation. Shortening the product development process and doubling the accuracy of the efficiency solution enables improvement of productivity of OEM and small & .

Although the present invention has been described with reference to a practical drawing (1) of an automobile part as an example, it can also be applied to a practical drawing (1) of a building, a ship, an airplane, In the case where the present invention is applied to a device other than a car, the center of the front wheel, which is the reference point of the curve, or the center of the engine is converted into the center point of the corresponding device in the color creating step S2. That is, the center of the front wheel or the center of the engine which forms the reference point in the automobile can be changed to the reference point of the apparatus in which the actual drawing is to be created.
