It should be noted that, related information (including, but not limited to, user equipment information, user personal information, etc.) and data (including, but not limited to, data for presentation, analyzed data, etc.) related to the present disclosure are information and data authorized by a user or sufficiently authorized by each party. For example, an interface is provided between the system and the relevant user or institution, before acquiring the relevant information, the system needs to send an acquisition request to the user or institution through the interface, and acquire the relevant information after receiving the consent information fed back by the user or institution.

The present application will be described with reference to preferred implementation steps, and fig. 2 is a flowchart of a method for processing a CAD drawing provided according to an embodiment of the present application, as shown in fig. 2, and the method includes the steps of:

step S201, obtaining N types of CAD drawings of a target product, wherein the N types of CAD drawings are drawings generated by using different types of CAD software, and N is a positive integer.

For example, the CAD drawing may be a three-dimensional drawing generated by CAD (Computer-AIDED DESIGN) tool software, and the CAD software may be three-dimensional design software, for example, the three-dimensional design software may be CAXA physical design software (a set of three-dimensional design software for industry), or the like. In addition, the N types of CAD drawings may be three-dimensional drawings generated using different types of three-dimensional design software (corresponding to the CAD software) corresponding to the product (corresponding to the target product).

Step S202, S first parts and T second parts are obtained from N types of CAD drawings, wherein the first parts are parts without identification information, the second parts are parts with identification information, and S and T are positive integers.

For example, model information of CAD drawings (corresponding to the above-described N types of CAD drawings) may be acquired by an SDK (Software Development Kit ) provided by CAD software, and common part information (corresponding to the above-described first part) and special part information (corresponding to the above-described second part) thereof (corresponding to the above-described N types of CAD drawings) are distinguished. Moreover, the model information of the CAD drawing may be the identification information, the attribute information, the upper-lower relationship between the parts, and the like of each part in the CAD drawing, and then all parts without the identification in the CAD drawing may be used as the normal parts (corresponding to the first parts described above) and all parts with the identification in the CAD drawing may be used as the special parts (corresponding to the second parts described above) according to the identification information of each part in the CAD drawing.

And step S203, converting the S first parts into a first part list, classifying each second part, and determining the category information of each second part.

For example, common parts (corresponding to the first part) in different types of CAD drawings can be directly converted into parts BOM (Bill of Materials ) through the plug-in (corresponding to the first part list); the specific parts (corresponding to the second parts) in the CAD drawings of different types can then be converted into specific abstract concepts (corresponding to the category information of the second parts) by the processing logic according to the configuration determination processing logic.

Step S204, converting the T second parts into a second part list based on the category information of each second part, and determining a target part list corresponding to the target product based on the first part list and the second part list.

For example, the abstract concept of a special part (corresponding to the second part) may be converted into a part BOM (corresponding to the second part list), and then the part BOM (corresponding to the first part list) of the normal part (corresponding to the first part list) and the part BOM (corresponding to the second part list) of the special part (corresponding to the second part) may be summarized together to obtain the target part list corresponding to the target product.

Through the steps S201 to S204, the special parts in all the CAD drawings of different types are classified into the special abstract concepts of several types in advance, then the abstract category to which the special part in the CAD drawing of the target product belongs is determined according to the special abstract concepts of several types in advance, then the part list corresponding to the special part in the CAD drawing is obtained according to the abstract category to which the special part in the CAD drawing of the target product belongs, and then the part list of the target product is determined according to the part list corresponding to the common part in the CAD drawing and the part list corresponding to the special part, so that the conversion logic of a set of part list can be specially designed for the CAD drawings generated by CAD software of different types, and further the effect of improving the efficiency of converting the CAD drawings of different types of the same product into the part list of the product is achieved.

Optionally, in the method for processing CAD drawings provided by the embodiment of the present application, obtaining N types of CAD drawings of a target product includes: y CAD drawing files corresponding to a target product are obtained, wherein Y is a positive integer greater than 1; analyzing each CAD drawing file to obtain suffix information of each CAD drawing file; determining the type information of each CAD drawing file according to the suffix information of each CAD drawing file; based on the type information of each CAD drawing file, N types of CAD drawings of the target product are obtained.

For example, the above Y CAD drawing files may be CAD drawing selected by the user to be extracted, then each CAD drawing file may be parsed to obtain a suffix of the drawing file, and then CAD types to which the drawing (corresponding to the above CAD drawing) belongs are distinguished according to the file suffix.

In summary, according to the suffix information of the CAD drawing file, the type of the CAD drawing can be rapidly and accurately distinguished.

Optionally, in the method for processing CAD drawings provided by the embodiment of the present application, acquiring S first parts and T second parts from the N types of CAD drawings includes: m parts are obtained from N types of CAD drawings, and identification information of each part is obtained, wherein M is a positive integer greater than 1; determining parts without identification information in the M parts according to the identification information of each part, and taking the parts without identification information in the M parts as S first parts; and determining the part with the identification information in the M parts, and taking the part with the identification information in the M parts as T second parts.

For example, the plug-in for processing the drawing may be selected according to the CAD type to which each drawing (corresponding to the CAD drawing described above) belongs, and then the plug-in may be processed by the CAD drawing to distinguish the parts into a normal part and a special part. For example, the identification information of each part can be obtained through a CAD drawing processing plug-in, all parts without the identification in the CAD drawing are used as common parts (corresponding to the first part), and all parts with the identification in the CAD drawing are used as special parts (corresponding to the second part).

By the scheme, the common part information and the special part information in the CAD drawing can be rapidly and accurately distinguished.

Optionally, in the method for processing a CAD drawing provided by the embodiment of the present application, converting S first parts into the first part list includes: acquiring attribute information of each first part, and acquiring upper and lower relationships among parts in the S first parts; the S first parts are converted into a first part list by the target plugin based on the attribute information of each first part and the upper-lower relationship between the parts in the S first parts.

For example, the attribute information of the first parts may be information such as a length, a weight, and a number of each common part (corresponding to each of the first parts) in the CAD drawing, and the upper-lower relationship between the parts in the S first parts may be an upper-lower relationship between the common parts (corresponding to the first parts) in the CAD drawing. For example, two common parts, namely a common part a and a common part B, exist in the CAD drawing, and if it is determined that the common part a includes the common part B, the common part a may be used as an upper part of the common part B, and the common part B may be used as a lower part of the common part a. The common parts (corresponding to the first parts) can directly pass through the plug-in (corresponding to the target plug-in), and the common parts (corresponding to the first parts) can be converted into the parts BOM (corresponding to the first parts list) according to the obtained information such as the length, the weight, the number and the like of the common parts (corresponding to the first parts) and the upper-lower relationship among the common parts (corresponding to the first parts).

In summary, the common part can be conveniently converted into the part BOM through the plug-in unit.

Optionally, in the processing method of CAD drawings provided in the embodiment of the present application, classifying each second part, and determining the category information of each second part includes: acquiring a processing strategy corresponding to each type of second part in the T second parts; determining processing logic for processing each second part based on the processing strategy corresponding to each type of second part; based on the processing logic that processes each second part, a categorization process is performed on each second part, determining category information for each second part.

For example, a particular part (corresponding to the second part described above) may be configured (corresponding to the processing policy described above) to determine processing logic, which may then be converted to a particular abstract concept (corresponding to the class information of the second part described above). Moreover, the processing strategy may be to categorize specific parts (corresponding to the second part) in all CAD into several specific abstract concepts, for example, mirror parts in one three-dimensional design software and mirror parts in another three-dimensional design software (such as entity design software), which may all be categorized as "mirror parts"; a compression element in three-dimensional design software and a non-drawing element in another three-dimensional design software (e.g., physical design software) may both be categorized as a "compression element". For example, if it is determined that the type of special part (corresponding to the second part) in the CAD drawing is a mirror part in three-dimensional design software, the special part (corresponding to the second part) may be classified as a "mirror part".

By the scheme, abstract category information corresponding to the special part can be rapidly and accurately determined according to the configuration information.

Optionally, in the processing method of a CAD drawing provided by the embodiment of the present application, the obtaining a processing policy corresponding to each type of second part in the T second parts includes: acquiring type information corresponding to each second part in the T second parts; determining K types of second parts according to the type information corresponding to each second part, wherein K is a positive integer; and acquiring a processing strategy corresponding to each type of second part in the T second parts based on the K types of second parts.

For example, classifying all special parts (corresponding to the second part) in CAD as several special abstract concepts (corresponding to the class information of the second part), such as mirror parts in one three-dimensional design software and mirror parts in another three-dimensional design software (such as entity design software), may be classified as "mirror parts"; a compression element in three-dimensional design software and a non-drawing element in another three-dimensional design software (e.g., physical design software) may both be categorized as a "compression element". In addition, as the types of CAD special parts to be supported are more and more, the function of converting various CAD special parts into abstract concepts is only needed to be realized, and the abstract concepts are loaded into a CAD drawing processing device through strategy configuration. For example, if the type of the special part (corresponding to the second part) in the CAD drawing is determined to be a mirror image part in the three-dimensional design software, the type of the special part (corresponding to the second part) may be determined, the processing policy corresponding to the special part (corresponding to the second part) may be determined, and the special part (corresponding to the second part) may be classified as an abstract concept according to the processing policy.

By the scheme, the processing strategy corresponding to the special part in the CAD drawing can be rapidly and accurately determined.

Optionally, in the processing method of CAD drawings provided in the embodiment of the present application, converting T second parts into the second part list based on the category information of each second part includes: acquiring attribute information of each second part, and acquiring upper and lower relationships among parts in the T second parts; the T second parts are converted into a second parts list based on the attribute information of each second part, the upper and lower relationships between the parts in the T second parts, and the category information of each second part.

For example, an abstract of a particular part (corresponding to each of the second parts described above) (corresponding to class information of the second parts described above) may be translated into a part BOM (corresponding to the second parts list described above). For example, the attribute information of the second parts may be information such as a length, a weight, and a number of each specific part (corresponding to each of the second parts) in the CAD drawing, and the upper-lower relationship between the parts in the T second parts may be an upper-lower relationship between the specific parts (corresponding to the second parts) in the CAD drawing. For example, two special parts, namely a special part a and a special part B, exist in the CAD drawing, and if it is determined that the special part a includes the special part B, the special part a may be used as an upper part of the special part B, and the special part B may be used as a lower part of the special part a. The specific part (corresponding to the second part) may then be converted into a part BOM (corresponding to the second part list) according to the obtained information such as the length, weight, number, etc. of the specific part (corresponding to the second part), the upper and lower relationships between the specific parts (corresponding to the second parts), and the abstract concept (corresponding to each of the second parts) of the specific part (corresponding to the category information of the second part).

In summary, the specific part can be quickly and accurately converted into the part BOM according to the abstract concept.

Optionally, in the method for processing a CAD drawing provided in the embodiment of the present application, after determining, based on the first part list and the second part list, a target part list corresponding to a target product, the method further includes: generating structural information of parts in a target product based on the target part list; and storing the structural information of the parts in the target product into a product structural tree of the target product, and displaying the product structural tree to the target object.

For example, all parts BOM (corresponding to the target parts list) may be structured and saved to a product structure tree (corresponding to the product structure tree of the target product), which may then be presented to a person (corresponding to the target object) who needs to use the part BOM (corresponding to the target product) of the product (corresponding to the target product).

Through the scheme, the product structure tree corresponding to the product can be obtained rapidly and accurately.

For example, the embodiment provides a method and a device for processing universal CAD drawings, from the mechanical design point of view, firstly constructing model concepts, then classifying the characteristics of different CAD drawings into the model concepts, and converting the characteristics into universal models by using the drawing data processing interface of CAD itself, so as to implement compatibility of the characteristics of different CAD drawings, improve the development efficiency of the device, reduce the development cost, and greatly improve the expandability of the device.

In this embodiment, from the actual needs and application situations in the mechanical design, model concepts are abstracted, and special parts in various CAD drawings are classified into the models according to specific use situations and actions, so that the process of converting the past special parts into part BOM is changed into an abstract model, and then the abstract model is converted into part BOM, thereby realizing compatibility of various CAD special parts and greatly reducing the development difficulty of CAD drawing processing devices.

For example, fig. 3 is a flowchart two of a processing method of a CAD drawing, where, as shown in fig. 3, the conversion of CAD drawing information into a part BOM is mainly divided into 2 steps:

(1) Model information extraction in CAD drawings

Model information of a CAD drawing is acquired through an SDK (Software Development Kit ) provided by CAD software, and common part information (corresponding to the first part) and special part information (corresponding to the second part) are distinguished.

(2) Conversion of model information to part BOM

A. the common part (corresponding to the first part) is directly converted into a part BOM;

b. determining the processing strategies of various special parts (corresponding to the second parts) through configuration;

c. all special parts are converted into abstract concepts through a processing strategy;

d. The abstract concepts are converted into part BOM.

For example, special parts in all CAD's may be categorized as several special abstractions, such as mirror parts in one three-dimensional design software and mirror parts in another three-dimensional design software (e.g., physical design software), and may be categorized as "mirror parts"; a compression element in three-dimensional design software and a non-drawing element in another three-dimensional design software (e.g., physical design software) may both be categorized as a "compression element". In addition, as the types of CAD special parts to be supported are more and more, the function of converting various CAD special parts into abstract concepts is only needed to be realized, and the abstract concepts are loaded into a CAD drawing processing device through strategy configuration.

For example, fig. 4 is a flowchart III of a processing method of CAD drawings provided according to an embodiment of the present application, and as shown in fig. 4, the processing method of CAD drawings may be divided into 5 steps:

1) The user selects CAD drawings to be extracted;

2) Distinguishing CAD types to which the drawing belongs according to the file suffix, and selecting plug-ins for processing the drawing according to the CAD types;

3) The plug-in is processed through CAD drawing, and the parts are divided into common parts and special parts;

4) The common part is directly converted into a part BOM through the plug-in, the special part determines processing logic according to configuration, the processing logic is converted into a specific abstract concept, and the abstract concept is converted into the part BOM;

5) And generating a structure by all parts BOM, and storing the structure on a product structure tree.

For example, in this embodiment, a special part may be converted into an abstract concept, and then into logic of a part BOM, and a middle layer, namely, an abstract model concept, is proposed; and the CAD drawing processing device can support dll plug-in (a software), and the function of converting different special parts into abstract concepts is inserted into the device through configuration processing strategies.

In addition, for the processing of special parts, only the function of converting the special parts into abstract concepts is needed to be realized, and the abstract concepts are allocated to corresponding processing strategies. In addition, the special parts in the CAD can find out the corresponding use scene in the mechanical design, namely the model concept can be abstracted, so that all the special parts can be processed into a specific abstract concept, and the device provided by the embodiment can be compatible with all the special parts and has very strong compatibility.
