[0002] In CAD software, the DWG file, as a file format for 2D CAD, has gradually become the de facto standard for 2D CAD file formats and is compatible with all CAD software. Some basic elements in DWG files, such as lines, circles, etc., are compatible with all CAD software. However, for the bill of materials object, since this object is not defined in the DWG file, each CAD manufacturer has its own implementation and it is not publicly available. For example, in AutoCAD Mechanical Edition, the bill of materials object is the proxy object AcmPartList, and the bill of materials in ZWCAD is a bunch of scattered blocks. When users switch CAD software or receive drawings sent by other manufacturers, they often find that although the bill of materials is displayed correctly, it cannot be edited and can only be treated as an ordinary block, which is extremely inconvenient and results in low software editing efficiency.

[0026] In order to enable those skilled in the art to better understand the solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0027] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily need to be used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances for the embodiments of the present application described herein.

For example, a process, method, system, product or device comprising a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these process, method, product or device.

[0028] According to the embodiments of the present application, a CAD file conversion method is provided.

[0029] Figure 1 It is the flowchart of the CAD file conversion method according to the embodiments of the present application. As Figure 1 shown, the method includes the following steps:

[0030] Step S101, in the target CAD software, read the target file object of the preset CAD software.

[0031] For example, in ZWCAD software, read the target file object in GstarCAD. Among them, the target file object may be some basic elements in a DWG file, such as a line, a circle, etc., or a bill of materials object.

[0032] Step S102, if the target file object is a bill of materials object, read the display data corresponding to the bill of materials object, where the display data is the data used to describe the bill of materials object.

[0033] Specifically, if the target file object is a bill of materials object, since this object is not defined in the DWG file, it is necessary to identify the bill of materials object in the DWG file.

[0034] Optionally, in the CAD file conversion method provided in the embodiments of the present application, after reading the target file object of the preset CAD software, the method further includes: obtaining the identification information of the target file object, where the identification information includes at least one of the following: the class name information of the target file object, the data block name information of the target file object; determining whether the target file object is a bill of materials object according to the identification information.

[0035] Specifically, the bill of materials object can be identified through the class name or block name of the DWG file and the specific identification information of the target file object. By identifying the bill of materials object, the parsing efficiency of the display data is further improved.

[0036] Optionally, in the CAD file conversion method provided in the embodiments of the present application, after reading the display data corresponding to the bill of materials object, the method further includes: randomly grouping the display data to obtain the grouped display data; determining whether there is text object data in the grouped display data; if there is text object data in the grouped display data, obtaining the text object data.

[0037] For example, the display data can be the coordinate position data of the objects in the bill of materials, as well as the color information, string text content, and font of the data in the objects in the bill of materials. They are randomly grouped after being scattered, and all text objects are filtered out. For example, the text objects can include string objects. By identifying the text object data, the bill of materials generated by other CAD software can be converted into a bill of materials object that can be recognized by the current CAD, which can greatly improve the editing efficiency.

[0038] Step S103, process the display data to obtain the target original data.

[0039] Specifically, analyze the text objects in the display data to further obtain the specifications of the bill of materials object.

[0040] Optionally, in the CAD file conversion method provided in the embodiments of the present application, before processing the display data to obtain the target original data, the method further includes: calculating the bounding box of the text object data; constructing the target cell information according to the bounding box, where the target cell information at least includes the row number information of the target cell and the column number information of the target cell.

[0041] For example, Figure 2 is a flowchart for reverse-deriving the original data from the display data of the CAD file conversion method provided by an embodiment of the present application. As Figure 2 shown, when the text object data is "Text A" and "Text B", calculate the bounding box sizes of Text A and Text B. Based on the bounding box, the M*N cells in the bill of materials (corresponding to the target cells in the present application) can be derived. Here, M represents the row information of the target cells, and N represents the column information of the target cells. By constructing the target cell information, the parsing efficiency of the target original data is improved, which can greatly improve the editing efficiency.

[0042] Optionally, in the CAD file conversion method provided by an embodiment of the present application, processing the display data to obtain the target original data includes: determining the data information of each row in the text object data according to the target cell information; determining the target original data according to the data information.

[0043] Specifically, as Figure 2 shown, determine the row information M in the M*N cells according to the text object, generate the data information of each row based on the cells, and determine the target original data based on the data information of each row. Here, the first row can be used as the header. By determining the target original data, the data of the bill of materials objects in different CAD software can be publicly utilized and can be edited secondarily, further improving the user experience.

[0044] Optionally, in the CAD file conversion method provided by an embodiment of the present application, determining the target original data according to the data information includes: obtaining the non-text object data in the display data; determining the target original data according to the data information and the non-text object data.

[0045] For example, the non-text object can be the distance between the upper and lower horizontal lines enclosing each row of data in a chart. The target original data is generated by adding all the row data and the non-text object data. By determining the target original data, the data of the bill of materials objects in different CAD software can be publicly utilized and can be edited secondarily, further improving the user experience.

[0046] Step S104, generating a target bill of materials according to the target original data.

[0047] Figure 3 is the overall operation flowchart of the CAD file conversion method provided by an embodiment of the present application. As Figure 3As shown in the figure, when reading a DWG file, for each bill of materials object, if it is an unknown bill of materials object, it is determined whether it is a bill of materials generated by other CAD software. The judgment basis can be the class name, block name, or some special identifiers, etc. If it is a bill of materials object, the display data is first read, and the display data is reversely deduced into the original data, and the original data of the target is used to generate the bill of materials object of the current CAD software, realizing that the data of the bill of materials object in different CAD software can be publicly utilized and can be secondarily edited, further improving the user experience.

[0048] In summary, the CAD file conversion method provided by the embodiments of the present application reads the target file object of the preset CAD software in the target CAD software; if the target file object is a bill of materials object, reads the display data corresponding to the bill of materials object, where the display data is the data used to describe the bill of materials object; processes the display data to obtain the target original data; and generates the target bill of materials according to the target original data. This solves the problem of low editing efficiency of CAD software in the related art. By processing the display data to obtain the target original data and generating the target bill of materials according to the target original data, the effect of improving the editing efficiency of the CAD software is achieved.
