The present invention relates to a graphics generation method, and more particularly to a graphics generation method and an auxiliary system thereof that can automatically perform graphics classification and comparison.

Traditionally, when circuit board layout and design are carried out, it is usually determined by the organization unit that the board appearance and the acceptable height and corresponding position of the components mounted on the board are transferred to the layout unit for wiring design of related components. .

However, because the board graphics drawn by the organization unit will contain many different layers, and the information displayed by each layer is not the same, such as showing the location map of a specific part on the board or the height limit map of the board. Therefore, after drawing the image, the user spends a lot of time on collating the image and the layer to obtain the desired information or layer classification. In addition, if the drawing format used by each drawing department is different, an additional format confirmation is required. Furthermore, institutional units often make corrections to the use environment, once If a certain correction point is omitted, and the corresponding correction is not made to the layout unit, it will cause subsequent wiring errors, which brings great inconvenience and trouble to the personnel of the two departments. In addition, it is traditionally the comparison before and after the correction by the painter himself. Since the graphics comparison work is rather cumbersome, it is a big burden for the opposite.

In order to make the description of the present invention more complete and complete, reference is made to the accompanying drawings and the accompanying drawings. However, the embodiments provided are not intended to limit the scope of the invention, and the description of the operation of the structure is not intended to limit the order of its execution, and any device that is recombined by the components produces equal devices. The scope covered by the invention.

The drawings are for illustrative purposes only and are not drawn to the original dimensions. On the other hand, well-known elements and steps are not described in the embodiments to avoid unnecessarily limiting the invention.

1 is a flow chart of a method of generating graphics in accordance with a preferred embodiment of the present invention. This graphic generation method 100 is used for a production The graphics are instant classified and versioned to reduce human error. The method for performing instant classification and version comparison can be implemented as a computer program and stored in a computer readable recording medium, so that a computer or an electronic device can read the recording medium and then execute The method of playing multimedia on a virtual desktop. Computer-readable recording media can be read-only memory, flash memory, floppy disk, hard disk, optical disk, flash drive, tape, network accessible database or familiar with the art can easily think of the same The function of the computer can read the recording medium.

The graphics generation method 100 first starts a graphics in step 101. An auxiliary system is generated, and then in step 110, a drawing mode is set to select a three-dimensional graphic or to draw according to the drawing mode to generate a three-dimensional graphic, and to classify the three-dimensional graphic according to the drawing mode. Traditionally, after completing the drawing of the board graphics, the organization engineers need to organize the drawings and layers to sort the relevant information, so as to provide subsequent layout units to design the wiring of related components, which is not convenient. Therefore, in the drawing of the present invention, the user can first set a drawing mode on a graphic generating system, so that the user selects a three-dimensional graphic or draws a sketch in the drawing mode, and when the drawing is completed, the sketch is drawn. This drawing mode is categorized directly. In an embodiment, the drawing mode may include a height-limit area drawing, a copper-exposed area drawing, and a white paint area drawing, but not limited to the above drawing mode. Accordingly, when a user selects a drawing mode for drawing a height-limited area, the user can select a three-dimensional circuit board graphic provided by the system according to the height-limiting area to be drawn, and the three-dimensional circuit board graphic is displayed thereon. A high-limit area is marked on the upper side to create a three-dimensional circuit board pattern with a limited height area. The system will then automatically classify the 3D board graphic according to this drawing mode, which is to classify it under the height limit area drawing category. Therefore, as far as the user is concerned, after the drawing is completed, it is not necessary to rearrange the image file and the layer to sort the relevant information required, and in addition to reducing the workload, the classification difference caused by the individual classification habit can be avoided. In another embodiment, if a finite height area has been drawn on the three-dimensional circuit board graphic, but the classification is not performed, the system can also classify the three-dimensional graphic according to the drawing mode set by the user. For example, if you select a height-limit area to draw, the system automatically classifies this 3D board graphic under the height-limited area drawing category.

Next, in step 120, the classified three-dimensional graphics are corresponding according to The drawing mode is converted to generate a two-dimensional preview image file, and each two-dimensional preview image file includes at least one two-dimensional graphic. In order to avoid errors in the exported image file, the system can provide a preview function before the user exports the image file, so that the user can confirm whether each graphic in the image file is wrong. The image file provided by the preview is a two-dimensional image file after classification, that is, although the user performs three-dimensional graphic drawing, the system converts the classified three-dimensional graphic into a two-dimensional preview image file. For the user to confirm. Therefore, in this system, the user only needs to perform three-dimensional graphic drawing, and the completed three-dimensional graphic is automatically converted into a two-dimensional graphic file, and corresponding two-dimensional preview graphics are generated according to the drawing category for the user to confirm. Therefore, the user does not need to perform file conversion and select the previewed two-dimensional graphics from the two-dimensional image file, and the system will automatically complete the conversion and provide a preview. The two-dimensional preview image file generated in the embodiment may include a plurality of two-dimensional graphics in three categories, which are two-dimensional graphics for displaying the height-limiting region, A two-dimensional figure showing the exposed copper area and a two-dimensional figure showing the white painted area are not limited to the above-mentioned figures.

In another embodiment, the case can automatically display the two-dimensional graphics automatically. The height limit area, the exposed copper area or the white paint area is divided into board information on the board or information under the board board. That is to say, before generating the two-dimensional preview image file in step 120, the present invention defines a virtual information dividing line and a circuit board located above the information dividing line according to the sectional view of the circuit board, about half of the thickness of the circuit board. Information is defined as on-board information, which is the front information of the board. The board information below the information split line is defined as the information under the board, that is, the information on the back of the board. According to the information dividing line, the generated two-dimensional preview graphics are further divided to display the information on the board and the information under the board in each category. In other words, the two-dimensional image included in the two-dimensional image file for displaying the height-limiting area, the exposed copper area, and the white lacquer area can be expanded into an upper limit area of the display panel, a lower limit of the lower limit of the board, and an exposed surface. Two-dimensional graphics of the copper area, the exposed copper area under the board, the white painted area on the board, and the white painted area under the board. Therefore, the step 110 may further include a region information segmentation process as shown in FIG. 2, in step 111, a virtual information segmentation line is defined in the three-dimensional graphic, wherein the graphic on the dividing line is defined as an on-board graphic, located here. The graphic below the dividing line is defined as the underlying graphic. And step 112, converting the classified three-dimensional graphics according to the virtual information dividing line to generate a two-dimensional preview image file, each two-dimensional preview image file comprising a plurality of two-dimensional graphics, respectively displaying the boards under each category Information and information under the board.

Next, in step 130, each two-dimensional graphic in the preview image file is exported according to a two-dimensional image file format. That is, when the user confirms this preview After the two-dimensional graphics in the image file have no errors, each two-dimensional graphics in the preview image file can be sequentially exported according to a two-dimensional image file format for archiving and subsequent comparison. In other words, the exported two-dimensional graphics are stored in a computer, for example, in a computer, and are also transmitted to a remote server for version comparison. In an embodiment, the two-dimensional image format is a DXF file format, where DXF is an abbreviation of Drawing Interchange Format or Drawing Exchange Format. According to the drawing mode of this case, the classification includes the height limit area, the exposed copper area and the white lacquer area. Therefore, the two-dimensional figure that is exported includes the upper limit area of the board, the lower area of the board, the area of the exposed copper area, and the board. The exposed copper area map, the white painted area on the board, the white painted area map, the block diagram and the parts data sheet and the part position map are not limited to this.

Next, in step 140, the two-dimensional graphics are compared with a historical image file to generate a comparison result analysis table. Since the product is often modified several times before the completion of the product, the mechanical design of the board is also the same. In order to avoid the problem of subsequent units caused by not informing the correction. Therefore, the system transmits the two-dimensional graphics to a comparison device to compare with the historical image files in the comparison device, and labels the difference points to generate a comparison result analysis table to feed back to the user end. In an embodiment, the comparison device is a server coupled to a plurality of user terminals, and can handle the comparison requirements of the user terminals. The two-dimensional graphic transmitted to the comparison device is stored as a historical image file for comparison with the next-time transmitted two-dimensional graphic. That is to say, the two-dimensional graphics transmitted this time will be compared with the previously transmitted two-dimensional graphics one-to-one, to confirm the difference between the two and to mark, for example, the difference can be marked in different colors. In another embodiment, the user You can also choose the version you want to compare with the two-dimensional graphics. It is not limited to comparing with the two-dimensional graphics that were transmitted before.

In addition, traditionally, when comparing, it is to use a two-dimensional diagram of the board. A specific position in the shape, such as a hole position, is used as a comparison reference point, and the alignment position offset can be avoided by superimposing each comparison pattern according to the reference point at each comparison. However, the board may undergo multiple corrections, causing specific positions to shift or disappear, affecting subsequent alignment results. Therefore, in order to ensure that each comparison is performed using the same fixed reference point, the present invention generates a special symbol (for example, a circle, outside the circuit pattern in the two-dimensional figure before the two-dimensional graphics are exported. As a reference point for the triangle, etc., in order to avoid misunderstanding, the special symbol can have a special size (this special size can be a very small size, the user end may not be visible to the naked eye, and the user can be prevented from misleading the drawing). Therefore, the comparison device can search for the comparison of the reference points by screening the special size. Since the comparison reference point is an extra setting and is outside the circuit pattern, even if the board is corrected, the comparison reference point is not affected, so the subsequent comparison result can be improved. Therefore, the step 140 of the present invention further includes a comparison flow as shown in FIG. 3, and step 141, a virtual comparison reference point is defined in the two-dimensional graphics that are exported, and in an embodiment, the comparison reference is used. The point is outside the point board graphic. For example, in the case of a notebook computer, the virtual comparison reference point is the position of the middle point between the two ends of the hinge. And in step 142, the two-dimensional graphics to be compared and a historical image file are superimposed according to the virtual comparison reference point to confirm the difference between the two and to mark up to generate a comparison result analysis table.

Finally, in step 150, the comparison result analysis table is transmitted for use. By. After the comparison device is completed, the comparison result analysis table is transmitted back to the user, and the user decides whether to start the graphic generation auxiliary system for drawing (step 101). Through the comparison result analysis table, the user can know the difference between the before and after versions, that is, the correction point. In addition to reminding the user whether the correction has been completely corrected, the subsequent unit can also be reminded to perform the corresponding correction. Because the comparison is performed by the comparison device, in addition to avoiding human error, the alignment accuracy can be increased.
