Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Aiming at the problems that the creation of the inspection rules depends on manual work and requires manual updating and maintenance of an expert in the prior art, the invention provides an inspection rule generation method for analyzing the fusion standard file and the CAD data, and fig. 1 is a flow diagram of the inspection rule generation method for analyzing the fusion standard file and the CAD data, provided by the embodiment of the invention, as shown in fig. 1, the inspection rule generation method for analyzing the fusion standard file and the CAD data comprises the following steps:
step 110: and obtaining a standard file and generating a rule set file based on the standard file.
FIG. 2 is a schematic flow chart of generating a rule set file according to an embodiment of the present invention, as shown in FIG. 2, in one embodiment, the obtaining a standard file, generating a rule set file based on the standard file includes the following steps:
Step 210: obtaining a standard file, wherein the standard file comprises a standard CAD file and/or an unstructured standard data file;
step 220: determining a standard data file based on the standard CAD file, the standard data file including all standard data in the standard CAD file;
Step 230: and generating the rule set file based on the standard data file and/or the unstructured standard data file, wherein the rule set file comprises all standard data in the standard CAD file and rules corresponding to all standard data in the unstructured standard data file.
Specifically, a standard file may be obtained, and the standard file may include a standard CAD file, an unstructured standard data file, and a standard CAD file and an unstructured standard data file. In the case where the acquired standard file includes a standard CAD file, all standard data in the standard CAD file, and thus, rules corresponding to all standard data in the standard CAD file may be determined based on the standard CAD file, and further, the standard data file may be determined based on the rules corresponding to all standard data in the standard CAD file (for example, a rule corresponding to one standard data in the standard CAD file may be determined based on that the line width of the thin solid line is 0.25b (b represents a line width basic unit), and thus, the standard data file is determined based on the rules). In the case that the acquired standard file includes an unstructured standard data file, rules corresponding to all standard data in the unstructured standard data file may be determined based on the unstructured standard data file (for example, rules corresponding to standard data of Chinese character height, english character and number height in the unstructured standard data file are that Chinese character height should be not less than 3.5mm and English character and number height should be not less than 2.5mm respectively). In the case where the acquired standard file includes a standard CAD file and an unstructured standard data file, a rule sentence may be generated based on rules corresponding to all standard data in the standard CAD file and all standard data in the unstructured standard data file, and finally the rule sentences are combined to generate a rule set file. It is readily understood that the rule set file may include rules corresponding to all of the standard data in the plurality of standard CAD files and rules corresponding to all of the standard data in the plurality of unstructured standard data files.
Optionally, the rule set files may be further managed in a grouping manner, for example, the rule set files are grouped for different companies, the rule set files corresponding to the company are determined for different companies, and when the CAD model to be inspected of the company needs to be inspected, the rule set files corresponding to the company are called to inspect the CAD model to be inspected. The rule set file automatically generated can be managed in a unified way through a rule base, such as management operations of new creation, storage, deletion, storage as well as regrouping and the like.
For example, a standard file that is commonly used by a company may be obtained, a standard data file corresponding to the company may be determined based on a standard CAD file that is commonly used by the company, and a rule set file corresponding to the company may be determined based on the standard data file corresponding to the company and/or an unstructured standard data file that is commonly used by the company. For example, a standard file "house building CAD drawing unified rule" commonly used by a building company may be obtained, and a rule set file corresponding to the company may be determined based on the standard file "house building CAD drawing unified rule".
In the above embodiment, the CAD file and/or the unstructured standard data file are acquired, and the rule set file is generated based on the CAD file and/or the unstructured standard data file, so that the inspection rule can be automatically constructed and updated, and the CAD model to be inspected can be automatically inspected based on the rule set file later.
Step 120: and acquiring a CAD model to be inspected, and determining a data file to be inspected based on the CAD model to be inspected, wherein the data file to be inspected comprises all data to be inspected of the CAD model to be inspected.
FIG. 3 is a schematic flow chart of determining a data file to be inspected according to an embodiment of the present invention, as shown in FIG. 3, in one embodiment, the determining the data file to be inspected based on the CAD model to be inspected includes the following steps:
step 310: invoking a CAD system corresponding to the CAD model to be checked based on the CAD model to be checked;
step 320: extracting object attributes and data attributes of each geometric element of the CAD model to be checked and original topological relations among the geometric elements from the CAD system;
Step 330: respectively associating object attributes and data attributes of the geometric elements and original topological relations among the geometric elements with the CAD model to be checked;
step 340: storing object attributes and data attributes of the geometric elements and original topological relations among the geometric elements into an XML file to obtain the data file to be checked;
The object attributes are classified and stored in the XML file in the form of text fragments.
Specifically, after the to-be-inspected CAD model is obtained, a CAD system corresponding to the to-be-inspected CAD model may be called based on the to-be-inspected CAD model, and then the object attribute, the data attribute, and the original topological relation between the geometric elements of the to-be-inspected CAD model may be extracted from the CAD system corresponding to the to-be-inspected CAD model. Geometric elements of the CAD model to be inspected may include title bars, frames, centerlines, break lines, roughness, geometric tolerances, and the like. Where the geometric element includes a title bar, the object properties of the geometric element may include: the data attributes of the geometric elements may include thick solid lines, thin solid lines, line widths, and colors: name, scale, graphic, product number, design code, and weight. Where the geometric element includes a frame, a centerline, a break line, roughness, and form and position tolerances, the object properties of the geometric element may include: the data attributes of the geometric elements may include, for example, graph configuration, line type, line width, and color: minimum bounding box coordinates and position coordinates. The original topological relation among the geometric elements can comprise topological relations among points, lines, planes and volumes, and can be topological relations such as point-to-point adjacency relation, point-to-plane inclusion relation, line-to-plane separation relation, plane-to-plane coincidence relation and the like. And then the object attribute and the data attribute of each geometric element and the original topological relation among the geometric elements can be respectively associated with the CAD model to be checked, for example, the object attribute and the data attribute of each geometric element and the Unique Identifier (UID) corresponding to the original topological relation among the geometric elements and the CAD model to be checked can be respectively set. The object attribute and the data attribute of each geometric element and the original topological relation among the geometric elements can be further stored in an XML file to obtain a data file to be checked, and the data file to be checked is obviously a file in an XML format. The object attributes may be classified in the form of text fragments, so as to obtain classified object attributes in the form of text fragments, and the classified object attributes in the form of text fragments may be stored in an XML file.
In the above embodiment, the object attribute and the data attribute of each geometric element of the CAD model to be inspected and the original topological relation between the geometric elements are determined based on the CAD model to be inspected, and then the object attribute and the data attribute of each geometric element after being associated with the CAD model to be inspected and the original topological relation between the geometric elements are stored in the XML file to determine the data file to be inspected. The method lays a foundation for determining the examination result based on the data file to be examined and the rule set file, and facilitates examination of the CAD model to be examined. In addition, in the embodiment, decoupling of the CAD model to be inspected and the rule set file is achieved, so that the inspected rule set file has better expansibility and flexibility.
Step 130: and determining the examination result of the CAD model to be examined based on the rule set file and the data file to be examined.
FIG. 4 is a schematic flow chart of determining a result of examination provided by an embodiment of the present invention, as shown in FIG. 4, in one embodiment, the determining the result of examination of the CAD model based on the rule set file and the data file to be examined includes the following steps:
step 410: matching and comparing the data file to be checked with the rule set file to determine a first checking result of the CAD model to be checked;
Step 420: determining shielding information among the geometric elements based on bounding box information and position information in the data attribute of each geometric element;
step 430: determining technological parameters of the CAD model to be inspected based on the original topological relation among the geometric elements;
step 440: determining a second examination result of the CAD model to be examined based on the shielding information and the technological parameters;
Step 450: and determining the examination result of the CAD model to be examined based on the first examination result and the second examination result.
Specifically, the data file to be inspected and the rule set file may be matched and compared, whether the header, the detail table, the line type and other conventional information in the data file to be inspected are matched with the header, the detail table, the line type and other conventional information in the rule set file or not is determined, and further, a first inspection result of the CAD model to be inspected is determined, where the first inspection result may include success and failure of matching, for example, a color of a line in the data file to be inspected is red, and a color of a line in the rule set file includes red, yellow and green, which indicates that the color of a line in the rule set file matched with the data file to be inspected exists, and further, it may be determined that the first inspection result of the CAD model to be inspected is successful. Because the first examination result can only reflect the examination result of the conventional information, and for more complex information, matching comparison cannot be directly carried out on the basis of the data file to be examined and the rule set file, more complex examination such as examination of the rationality of the process is determined by the second examination result. Occlusion information between geometric elements can be further determined based on bounding box information and position information in data attributes of the geometric elements, for example, occlusion between any two planes can be determined based on bounding box information and position information in data attributes of the two planes, and as occlusion cannot exist between the planes, a second examination result of the CAD model to be examined can be determined to be examination failure. And the process parameters of the CAD model to be inspected can be determined based on the original topological relation among the geometric elements, for example, the process characteristic identification and calculation can be performed based on the inner and outer closed loop judgment rules of the model, and further the process parameters of the CAD model to be inspected can be determined based on the original topological relation between the square plane of the outer ring instance and the circular hole of the inner net instance in the square plane, namely, whether the connection position from the edge of the circular hole in the square plane to the edge of the square plane meets the preset distance can be determined, and the connection position is possibly broken due to the fact that the connection position is not met, so that the rationality inspection of the process is unqualified, and the second inspection result is inspection failure. A second inspection result of the CAD model to be inspected may further be determined based on the occlusion information and the process parameters, and the second inspection result may include inspection success and inspection failure.
Finally, the censoring results of the CAD model to be censored may be determined based on the first censoring results and the second censoring results, e.g., the censoring results of the CAD model to be censored may include censoring passed and censoring failed.
Further, an inspection report can be generated based on the matching condition of the data file to be inspected and the rule set file, shielding information among the geometric elements and the technological parameters of the CAD model to be inspected, and the inspection report can comprise a first inspection result, a second inspection result and an inspection result of the CAD model to be inspected.
Alternatively, in the case where the first examination result is a failure in matching, that is, in the case where the conventional information such as the title bar, the detail table, and the line type in the data file to be examined is not matched with the conventional information such as the title bar, the detail table, and the line type in the rule set file, the examination result for examining the CAD model may be directly determined based on the first examination result without determining the second examination result.
In the above embodiment, the first and second examination results of the CAD model to be examined are determined based on the rule set file and the data file to be examined, and the examination result of the CAD model to be examined is further determined based on the first and second examination results, thereby completing the automatic examination of the CAD model.
According to the method for generating the examination rules by fusing the standard file and the CAD data analysis, the rule set file can be automatically generated based on the standard file by acquiring the standard file, the CAD model to be examined is acquired, and the data file to be examined is determined based on the CAD model to be examined, wherein the data file to be examined comprises all data to be examined of the CAD model to be examined. And furthermore, the CAD model to be inspected can be automatically inspected based on the rule set file and the data file to be inspected, and the inspection result of the CAD model to be inspected is determined, so that the creation and the update of the inspection rule are not dependent on manual operations of an expert, the automation of the creation and the update of the inspection rule is realized, a great deal of time cost and labor cost are saved, and the method is suitable for the field of rapid development or special requirements, thereby improving the rapid adaptability of a model inspection system to new standards or changes and facilitating the inspection of the CAD model.
In one embodiment, the method further comprises:
Visually outputting the rule set file;
And processing the rule set file based on a rule operation instruction to obtain a processed rule set file, wherein the rule operation instruction comprises a modification instruction and/or a retrieval instruction.
Specifically, the rule set file may be visually output to the display interface, and a rule operation instruction may be received, where the rule operation instruction may be manually input, or may be sent by another terminal, and after receiving the rule operation instruction, the rule set file may be processed based on the rule operation instruction, to obtain a processed rule set file, where the rule operation instruction includes a modification instruction (where the modification instruction may also include an addition instruction, an update instruction, and a deletion instruction) and/or a search instruction. For example, after receiving a manually input search instruction, a search operation may be performed in the rule set file to obtain a rule set file corresponding to the search instruction.
In the embodiment, the rule set file is visually output, so that a user can intuitively observe the examination rules in the rule set file, and the rule set file can be processed based on the rule operation instructions, so that the processed rule set file is obtained, and the user can conveniently modify and inquire the rule set file.
In one embodiment, the processing the rule set file based on the rule operation instruction to obtain a processed rule set file includes:
