Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of data processing, and in particular to a three-dimensional model design quality checking method and device, electronic equipment and medium. BACKGROUND

[0002] In the process of widely applying three-dimensional models in engineering design, manufacturing, simulation and other fields, the quality of model design directly affects the efficiency and accuracy of subsequent production, assembly, performance analysis and other links. Therefore, it is crucial to check the design quality of three-dimensional models (such as size tolerance, geometric constraint, assembly gap, design specification compliance, etc.).

[0003] At present, the conventional three-dimensional model quality checking method mainly has the following significant defects:

[0004] Highly dependent on manual operation, low efficiency and high cost: the inspection personnel usually need to manually measure, view and compare different parameters and features of the model repeatedly in the three-dimensional design software to verify whether they meet the design requirements or standard specifications. For complex models or large batch inspection tasks, this process is extremely time-consuming and laborious, becoming a bottleneck in the design process.

[0005] Strong subjectivity, prone to errors and poor consistency: the results of manual inspection largely depend on the experience, attentiveness and understanding of the standard of the inspection personnel. Different personnel may have different results for the same model or the same personnel may have different results at different times, which may deviate or even miss critical errors (such as slight interference, not meeting the minimum wall thickness, etc.), resulting in unreliable inspection results and hidden dangers for subsequent processes.

[0006] Poor traceability of the inspection process and tedious report generation: the process and basis of manual inspection are difficult to be recorded completely and objectively. Generating a detailed inspection report requires additional investment of a lot of time to organize measurement data, screenshots and judgment basis, and the report format and quality also vary from person to person, which is not conducive to traceability analysis and continuous improvement of quality problems.

[0007] Difficult to deal with complex rules and batch processing: for inspection items involving multiple parameter associations and complex logical judgments (such as minimum distance in a specific area, specific angle range), manual inspection is not only extremely inefficient, but also almost impossible to guarantee comprehensiveness and accuracy. At the same time, there is a lack of effective automation means to handle repetitive inspection tasks of large batches of models. SUMMARY

[0008] The main purpose of the embodiments of the present application is to propose a three-dimensional model design quality checking method, device, electronic equipment and medium, so as to solve at least one problem of the prior art, and the present application can efficiently and accurately realize three-dimensional model design quality checking.

[0025] In some embodiments, the target model parameter is subjected to the check judgment based on the check logic corresponding to the check item, including the following steps:

[0071] Figure 1 is an optional flowchart of the three-dimensional model design quality checking method provided by the embodiments of the present application, Figure 1 The method in the above can include, but is not limited to, steps S100 to S400.

[0072] S100, obtaining a three-dimensional model to be checked;

[0073] It should be noted that in some embodiments, obtaining a three-dimensional model to be checked can include the following steps: obtaining a three-dimensional model from import data of a target object in response to an import instruction of the target object.

[0074] For example, in some specific implementations, the target object may refer to the specific 3D model file to be inspected, or may refer to a design project, assembly, or a specific inspection task containing the 3D model. For example:

[0075] The user selects a model file named `Engine_Block.stp` in the software interface and clicks the "Start Check" button. At this point, `Engine_Block.stp` becomes the "target object," and the user's click generates an "import instruction" for that file.

[0076] In the Project Manager, a user selects a design project named `New_Product_Assembly`, which contains several part and subassembly models. The user right-clicks the project and selects "Run Design Check." The `New_Product_Assembly` project becomes the "target object," and the user's menu selection generates an "import command" for that project.

[0077] The automated script calls the inspection program's API, passing in the parameter `task_id = 12345`. The system queries the database based on `task_id = 12345` and finds the master model file `Housing_Casting.par` associated with this task. At this point, `task ID 12345` represents the "target object," and the API call triggers the "import instruction."

[0078] It should also be noted that the triggering methods of "import instructions" include but are not limited to:

[0079] Graphical user interface (GUI) interaction: such as clicking a button, dragging and dropping a file to a specified area, selecting a menu item, double-clicking a file icon, etc.

[0080] Command Line Interface (CLI): Users or scripts enter commands containing the model path or identifier in the command line, such as `check_model --file "C:\models\valve_body.ipt"`.

[0081] Application Programming Interface (API) call: Other software systems or scripts trigger the import by calling the API function provided by this method and passing the target object identifier (such as file path, database ID, URL, etc.).

[0082] Task queue / workflow engine driven: In the automated pipeline, after the upstream task is completed (such as model design completion or simulation end), the model identifier is placed in the queue, and the inspection system takes the identifier from the queue and triggers the import instruction.

[0083] S200, in response to the target object inspection starting instruction, extracting a target model parameter from the three-dimensional model based on a preset inspection item;

[0084] It should be noted that the inspection items include virtual part inspection, check-in inspection, design standard inspection, hole standard inspection, offset hole inspection, missing hole inspection, burst hole inspection and interference inspection; in some embodiments, extracting the target model parameter from the three-dimensional model based on the preset inspection item can include the following steps: when the inspection item is virtual part inspection, extracting first model data from the three-dimensional model as the target model parameter; wherein the first model data includes virtual value parameters of each part and the dependency relationship between the parts; when the inspection item is check-in inspection, extracting second model data from the three-dimensional model as the target model parameter; wherein the second model data includes model design parameters, material parameters and specification parameters; when the inspection item is design standard inspection, extracting third model data from the three-dimensional model as the target model parameter; wherein the third model data includes parameter information of the target material; when the inspection item is hole standard inspection, extracting fourth model data from the three-dimensional model as the target model parameter; wherein the fourth model data includes hole specification parameters; when the inspection item is offset hole inspection, extracting fifth model data from the three-dimensional model as the target model parameter; wherein the fifth model data includes hole position parameters; when the inspection item is missing hole inspection, extracting sixth model data from the three-dimensional model as the target model parameter; wherein the sixth model data includes hole matching relationship parameters; when the inspection item is burst hole inspection, extracting seventh model data from the three-dimensional model as the target model parameter; wherein the seventh model data includes hole specification parameters, hole position parameters and hole matching relationship parameters; when the inspection item is interference inspection, extracting eighth model data from the three-dimensional model as the target model parameter; wherein the eighth model data includes interference parameters between the parts.

[0085] Exemplarily, in some specific embodiments, the data basis principles of each inspection item are as follows:

[0086] 1. Virtual part inspection: Virtual parts generally refer to parts in an assembly that are used to assist positioning, reference or simplify expression, and do not participate in manufacturing (such as placeholders for reference planes, construction lines, positioning pins). The core problem is: whether virtual parts that should not be actually manufactured or purchased are mixed in the design file? Is the hierarchical relationship between virtual parts correct?

[0087] Example extraction (first model data): `Virtual value parameters`: explicit `virtual part` markers in part attributes (such as `IsPhantom = true`), specific naming conventions (such as `Ref_`), or specific types (such as `ConstructionGeometry`); `Dependency relationship between parts`: assembly structure tree (BOM structure), explicitly indicating the level of virtual parts (whether it is a reference of the top assembly or a sub-component of an actual part).

[0088] 2. Check-in Check: To ensure that the model contains necessary basic metadata before being stored in the PDM / PLM system or shared library, meeting the minimum information requirements of downstream processes (such as manufacturing, procurement, analysis).

[0089] Example extraction (second model data): `Model design parameters`: part number, version number, revision number, designer, design date, etc.; `Material parameters`: specified material name (such as `AISI 304`), material code, material standard (such as `ASTM A276`); `Specification parameters`: weight (calculated value or attribute value), key dimensions (such as outer dimensions `LxWxH`), applicable product / project number.

[0090] 3. Design Standard Check: Verify whether the specific materials (target materials) in the model meet the predefined, more detailed design rules or enterprise standards (non-basic metadata).

[0091] Example extraction (third model data): `Parameter information of target materials`: refers to the key design parameters of specific types of parts or features, for example: for sheet metal parts: sheet thickness, bending radius, bending angle, K factor, crack stop groove size; for shaft parts: diameter, length, keyway size, tolerance fit (such as `H7 / g6`), surface roughness; for gears: modulus, number of teeth, pressure angle, tooth width; for plastic parts: wall thickness, draft angle, reinforcement rib size

[0092] 4. Hole Standard Check: Ensure that the features of the hole (such as threaded hole, light hole, countersunk hole) meet the selected standards (such as ISO, DIN, ANSI) or internal specifications.

[0093] Example extraction (fourth model data): `Hole specification parameters`: hole standard type (such as `M6 Clearance Hole`, `1 / 4-20UNC Tapped Hole`, `ISO 4762 M8x1.25 Counterbore`), hole diameter, hole depth, thread specification (diameter, pitch, tolerance level), countersink / countersunk hole size (diameter, angle, depth).

[0094] 5. Offset Hole Check: Check whether the actual center position of the hole deviates from its theoretical design position beyond the allowable tolerance range. This is crucial for assembly accuracy.

[0095] Example extraction (`fifth model data`): `Hole position parameters`: theoretical design coordinates of the hole (relative to the reference coordinate system or specific features), actual modeling coordinates, position tolerance (such as `±0.1mm` or `Position Tol 0.2A|B|C`), and the center position relationship of the corresponding two matching hole pairs, etc.

[0096] 6. Hole pairing check: Ensure that in places where a pair connection is required (e.g. two parts that need to be bolted together), the corresponding holes are correctly drilled on both parts (e.g. one part is threaded, the other is a matching hole).

[0097] Example extraction (sixth model data): `Hole pairing relationship parameters`: Identify potential pairing locations (e.g. through assembly constraints, proximity analysis, or predefined pairing rules), then extract the presence and type of hole features on both sides of the pair at the corresponding locations (e.g. threaded hole vs matching hole).

[0098] 7. Hole burst check: Check if a hole is at risk of insufficient wall strength (too thin wall thickness) or hole mouth breakage due to being too close to a part edge. This is a combined check of hole location and specification.

[0099] Example extraction (seventh model data): `Hole specification parameters`: (same as hole standard check) hole diameter; `Hole location parameters`: (same as hole offset check) hole center coordinates for distance calculation to edge; `Hole pairing relationship parameters`: (same as hole pairing check) for determining the importance of the hole or the required minimum wall thickness. Additional calculation / extraction required: minimum distance from hole center to nearest part edge.

[0100] 8. Interference check: Check if there are unintended overlaps (hard interference) or too small gaps (soft interference) between parts in the assembly, affecting assembly or functionality.

[0101] Example extraction (eighth model data): `Interference between parts parameters`: Based on preset operation logic, interference analysis calculation results using raw data of three-dimensional models, including: interference pair: identification of two (or more) parts that interfere; interference type: hard interference (solid overlap), soft interference (gap less than a set threshold, such as 0.1mm); interference amount / gap value: volume of overlapping area or maximum penetration depth / minimum gap distance; interference area location / identification: bounding box, approximate location description, or specific face identification (for highlighting).

[0102] S300, based on the check logic corresponding to the check item, performing check judgment on the target model parameters;

[0103] It should be noted that in some embodiments, step S300 can include the following steps:

[0104] S301, when the check item is a virtual part check, determining the state value of the virtual value parameter of each part based on the first model data, sorting the parts with the virtual value parameter as the first state value to obtain a virtual part list, determining the parent component of each part based on the dependency relationship, and excluding the parts with the virtual value parameter as the second state value of the parent component from the virtual part list.

[0105] Exemplarily, in some specific embodiments, the virtual part inspection logic can be implemented as follows:

[0106] 1. Virtual part definition: judging whether the virtual value parameter VIRTUALPART is "NO", "NO" (second state value) indicating a physical part, and "YES" (first state value) indicating a virtual part (for display, no need to purchase or produce the part);

[0107] 2. Items with the virtual value parameter "YES" are listed and displayed in the tool list, and the model position can be highlighted by clicking the row;

[0108] 3. Items with the parent assembly of the part being "NO" are excluded, and this type is a component drawing, the part itself is included in the assembly, no need to be handled separately, and the problem display quantity is reduced, and the positioning is more accurate;

[0109] 4. This inspection item mainly solves the problems of not missing and not over-issuing when issuing model mechanism parts, and improves the quality of list issuance.

[0110] In some optional embodiments, the conditions for completing and closing the virtual part inspection can be set as: 1. The parameter of the physical part is switched to "NO"; 2. The reason is stated in the remarks; and 3. The parameter is confirmed to be correct.

[0111] S302, when the inspection item is an import inspection, performing consistency comparison on the second model data based on a preset parameter, and / or performing data format compliance judgment on the second model data based on a preset parameter specification;

[0112] Exemplarily, in some specific embodiments, the import inspection logic can be implemented as follows:

[0113] 1. Import inspection definition: checking the necessary parameters of the model, and meeting the requirements of the uploading system;

[0114] 2. Inspection logic:

[0115] 2.1 The designer, name and process parameter are not allowed to have null values;

[0116] 2.2 Whether the model tree name and the drawing number name parameter values are consistent;

[0117] 2.3 Whether the material parameter exists in the latest material library, to ensure that the used material is the latest material;

[0118] 2.4 When the name starts with the letter B and is followed by 4-5 digits, checking whether the softtype parameter value is cn.com.banchengpin;

[0119] 2.5 The softtype parameter value cannot be empty;

[0120] 2.6 The model relationship formula cannot be empty;

[0121] 2.7 Whether the specifications of the secondary processing parts are in the standard list;

[0122] 3. This check item mainly solves the problems of model parameters, material use, specification use, etc., and improves the quality of model parameters.

[0123] S303, when the check item is a design standard check, performing first standard judgment on the third model data based on a preset parameter standard, and / or performing second standard judgment on the position relationship between target materials based on a preset distance standard; wherein the position relationship is obtained by converting parameter information of each target material;

[0124] Exemplarily, in some specific embodiments, the design standard check logic can be implemented as follows:

[0125] 1. Check definition: automatically check the model mechanism design standard, and list the materials that do not meet the design standard;

[0126] 2. Introduction of check-in check logic examples:

[0127] 2.1 Check item: synchronous wheel installation requirement: check the synchronous wheel, and then check whether the depth of the shaft sleeve matched with the synchronous wheel reaches more than 2 / 3, and if the depth is insufficient, an error is reported;

[0128] 2.2 Check logic:

[0129] First step: obtain the materials with the name parameter containing "synchronous wheel" or "synchronous pulley" from the stored information;

[0130] Second step: find the material in contact with the material and the name parameter containing "shaft";

[0131] Third step: find the contact surfaces of the two materials respectively and mark them, obtain the center points of the upper and lower ends of the two surfaces respectively, sort them in the axial direction of the surface, and take the middle two points to measure the distance;

[0132] Fourth step: take the center points of the two sections of the synchronous wheel marked surface, and measure the distance;

[0133] Fifth step: compare whether the third step reaches 2 / 3 of the fourth step;

[0134] Sixth step: collect the material information that does not meet the condition, and display error information according to different cases;

[0135] 3. This check item mainly solves the design standard errors, automatically checks through the program, and improves the checking efficiency and quality.

[0136] In addition, in some specific application scenarios, the design standard check can also define the following types:

[0137] 1.

[0152] 2. Logic;

[0154] 2) No matching check between purchased parts and purchased parts, no matching check between enterprise standard parts and enterprise standard parts, and other matching combinations need to be checked;

[0155] 3) If the holes are matched, the edge margin between the two holes intersects, and the hole misalignment is identified (different from the hole missing);

[0156] 4) U-shaped hole and threaded hole are matched, the axis of the threaded hole is not in the center of the U-shaped hole, and the hole misalignment is identified;

[0157] 5) Add configuration items (according to name, figure number), and do not identify special parts, each threaded hole corresponds to a matching hole, and when one matching is successful, the two holes do not match with other holes;

[0158] 3. This check item mainly solves the position problem between the matching holes of model mechanism parts, and reduces the abnormal assembly rate.

[0159] S306, when the check item is hole missing checking, the hole matching relationship parameters are judged based on the preset hole missing checking logic;

[0160] Exemplarily, in some embodiments, the hole missing checking logic can be implemented as follows:

[0167] 5) Exclude the error message of the missing hole on the purchased part.

[0168] 3. This check item mainly solves the problem of missing design of paired holes of model mechanism parts, and reduces the abnormal rate of missing processing features and assembly.

[0169] S307, when the check item is a burst hole check, the seventh model data is checked and judged based on the preset burst hole check logic;

[0170] Exemplarily, in some embodiments, the burst hole check logic can be implemented as follows:

[0171] 1. Check definition: check if the hole is damaged;

[0172] 2. Logic;

[0173] 1) Purchased parts and enterprise standard parts are not within the burst hole check range.

[0174] 2) Objects containing "CP" in the model name are not within the burst hole check range.

[0175] 3) Crossed holes (threaded holes and through holes, threaded holes and threaded holes, and through holes and through holes) are identified as burst holes, and error messages are prompted.

[0176] ① Check two holes perpendicular to the same reference surface, and perform comparison calculation to determine whether the burst hole exists.

[0177] ② Check two holes perpendicular to and parallel to the same reference surface, and perform comparison calculation to determine whether the burst hole exists.

[0178] 4) When the hole edge distance from the part edge is less than 1mm, it is identified as a burst hole, and an error message is prompted. The hole and the surface need to be highlighted.

[0179] 5) A through hole with a length greater than 30mm and a threaded hole intersecting it vertically in the center is not a burst hole.

[0181] S308, when the check item is an interference check, the interference parameters between the target parts are checked and judged based on the preset interference check logic;

[0182] Exemplarily, in some embodiments, the interference check logic can be implemented as follows:

[0191] 7) The exclusion function can greatly reduce the number of false interference problems, is better than other interference checking software, improves the inspection efficiency, and can be sorted according to the part category and interference volume.

[0192] 3. This inspection item mainly solves the interference problem between model mechanism parts, and reduces the assembly abnormality rate.

[0193] In some embodiments, the method can further include the steps of: pushing the result of the inspection judgment to the target object to obtain an inspection instruction fed back by the target object; wherein the inspection instruction includes a model adjustment instruction; in response to the model adjustment instruction, adjusting the target model parameter of the three-dimensional model; and importing the result of the adjustment processing into an inspection report.

[0194] Exemplarily, in some specific embodiments, the above embodiments can be implemented as follows:

[0195] 1. Push the result of the inspection judgment to the target object:

[0196] The target object here can refer to the source that triggers the inspection or the subject responsible for processing the inspection result, which can be a designer / engineer. For example, in an interactive scenario, the target object is a user operating a 3D model software.

[0197] Pushing method: integrated plug-in / tool bar notification: directly pop up a notification window in the software interface being operated by the user, display a result list in the task panel, or highlight the problem features in the model view.

[0198] The pushed content includes but is not limited to: the name and status of the inspection item (pass / fail / warning); the specific description and reason of the failure / warning; the specific model location of the problem (part name, feature ID, coordinate range); relevant parameter values ​​and expected values / ranges; visual screenshots or view links; and actionable options (leading to "feedback inspection instructions").

[0199] 2. Inspection instructions to obtain feedback from the target object:

[0200] Use the pushed results to provide an interactive interface for the target user to provide feedback instructions. For example, GUI buttons / menus: provide buttons such as "Ignore", "Mark as Reviewed", "View Details", and "Adjust Model" in the result notification window or issue list.

[0201] Parameter identification: Clearly specify the target model parameters that need to be adjusted (such as the diameter of hole A, the thickness of part B, the offset of feature C, etc.).

[0202] Adjustment actions include but are not limited to: direct assignment: `Set parameter X to value Y` (such as `Set the diameter of hole D = 8.5mm`); incremental adjustment: `Increase / decrease parameter X by value Delta` (such as `Increase the wall thickness by 0.5mm`); rule-based adjustment: `Adjust parameter X according to rule R` (such as `Automatically calculate and set the distance from hole E to the edge according to the minimum wall thickness rule`); feature operation: `Delete feature F`, `Move feature G to position P`.

[0203] 3. In response to the model adjustment instruction, adjust the target model parameters of the three-dimensional model:

[0204] Adjustment execution: The system interprets the adjustment instructions and invokes the corresponding model manipulation engine to perform the modification. Specifically, adjustments are made to the target model parameters identified during the previous inspection as causing the failure of a specific inspection item. Rather than blindly modifying the entire model, the system pinpoints and repairs the problem.

[0205] 4. Import the adjustment results into the inspection report:

[0206] Adjustment actions and their results are recorded and incorporated into the final or updated inspection report.

[0207] Records include but are not limited to:

[0208] Details of the adjustment instructions executed: which parameter was adjusted, how it was adjusted (old value → new value), when it was adjusted, and who / what triggered the adjustment.

[0209] Adjusted Verification: Automatically or manually trigger a quick re-inspection of that specific inspection item (or related items) and record the new inspection result (which should become passed).

[0210] Model version association: record the new model version identification generated after adjustment.

[0211] Report embodiment: add status (such as “repaired”) next to the original inspection item result, add a “repair history” section, or add a “correction measure summary” at the end of the report.

[0212] The embodiment of the application adds a closed-loop link of “result pushing → feedback instruction → model adjustment → result recording” after the core inspection process (acquisition → extraction → judgment → report), which upgrades the application from an “automated quality inspection tool” to an “intelligent quality inspection repair assistant”. It effectively solves the core pain points of low efficiency, easy omission, easy error, and difficult traceability in the “correction link” of the traditional inspection process, realizes the rapid closed-loop processing of quality problems, and significantly improves the design efficiency, model quality, and process control level. This active pushing, instruction-driven, automatic execution, and complete recording closed-loop mechanism is an important symbol that distinguishes the application scheme from the prior art in terms of practicality and intelligence.

[0213] It should be further pointed out that when the number of inspection items is greater than 1, the inspection instruction further includes a determination instruction, and in some embodiments, step S300 can include the following steps: S311, acquiring a preset inspection order, and taking the first inspection item in the inspection order as a target inspection item; S312, performing inspection and judgment on the target model parameter corresponding to the target inspection item based on the target inspection logic corresponding to the target inspection item; S313, when obtaining the determination instruction of the target object to the target inspection item, taking the next inspection item in the inspection order as the target inspection item, and returning to execute the step of performing inspection and judgment on the target model parameter corresponding to the target inspection item based on the target inspection logic corresponding to the target inspection item, until all inspection items are completed.

[0214] Exemplarily, in some specific embodiments, the inspection of the part Valve_Housing is started in response to the operation of the user. For example, the preset order is: 1. check-in inspection, 2. hole standard inspection, 3. interference inspection, and the execution logic can be implemented as follows:

[0215] S311: The system acquires the order and sets the first check-in inspection as the target inspection item.

[0216] S312: The system executes the check-in inspection logic (checks the metadata integrity), and the result shows “material parameter missing”.

[0217] The system shows the user on the interface: “check-in inspection completed: 1 failed (material missing). Please confirm...”. The user has viewed the prompt and clicked the “confirm and continue” button (determination instruction).

[0218] S313: The system receives the instruction, updates the target inspection item to the next hole standard inspection, and returns to S312.

[0219] S312: The system executes the hole standard inspection logic (inspects all hole specifications), and the result shows that the "M8 threaded hole depth is insufficient".

[0220] The system displays: "Hole standard inspection completed: 1 failed (M8 hole depth insufficient). Please confirm...". The user clicks "Confirm and continue" again.

[0221] S313: The system updates the target inspection item to the last interference check, and returns to S312.

[0222] S312: The system executes the interference check (calculates whether there is interference between the internal cavity and the wall of the part), and the result shows "no interference".

[0223] The system displays: "Interference check completed: passed. Please confirm...". The user clicks "Confirm".

[0224] S313: The system determines that all inspection items have been completed, and the entire inspection judgment process ends. The system starts to integrate the results to generate a report.

[0225] The core of the embodiments of the present application is the mechanism of "sequential execution + item-by-item confirmation promotion": controllable sequence: through the preset sequence, the order of inspection execution is managed; user / system participation: the determination instruction is introduced to force the immediate confirmation of the result of each inspection item, ensuring that the process is visible and controllable. The user can pause, view the result, and then decide whether to continue after each step; resource management (potential): for inspection items with large calculation amount (such as interference check), they are executed at the end. If the previous inspection item has found a serious error (such as missing key metadata), the user may choose to terminate the inspection or repair first, avoiding unnecessary resource consumption; clear process: making the complex multi-step inspection process structured and traceable.

[0226] It should be further noted that the inspection instruction also includes a selection instruction, and the target model parameters corresponding to each inspection judgment and the corresponding part of the three-dimensional model have a mapping relationship preset; in some embodiments, the method can further include the following steps: in response to the selection instruction of the target result item in the result of the inspection judgment of the target object, the target part in the three-dimensional model is prompted and marked based on the mapping relationship.

[0227] Exemplarily, in some specific embodiments, taking the interference check as an example, the above embodiments can achieve the following:

[0228] Inspection execution: the system performs an interference check on the assembly Pump_Assembly.

[0229] Report generation: Check report shows a failure item: [Severe interference] Part 'Shaft' (ID: P-1001) interferes with part 'Bearing_Housing' (ID: P-2005) with a penetration depth of 0.5mm.

[0230] User operation (selection instruction): The design engineer clicks on this interference failure record in the report list (target result item).

[0231] System response (prompt marker): The system immediately locates the Shaft and Bearing_Housing in the model according to the preset mapping relationship (the result item is bound to part IDs P-1001 and P-2005).

[0232] In the three-dimensional model view window: the Shaft part is highlighted in red and the Bearing_Housing part is highlighted in orange, the view is automatically rotated and zoomed in, focusing on the area where the two parts intersect. A semi-transparent color block area can also be displayed at the specific location where the interference occurs.

[0233] Effect: The engineer can quickly find out which part of the Shaft and Bearing_Housing is interfering, without manually searching in the complex assembly, greatly improving the efficiency of problem positioning and subsequent repair.

[0234] The embodiments of the present application realize seamless, accurate and efficient mapping from abstract inspection results to specific model locations by presetting the mapping relationship between inspection results and model elements and responding to the user's selection instruction to provide visual prompt markers. This is one of the key features to improve the practicality and user experience of three-dimensional model quality inspection tools.

[0235] S400, integrate the results of the inspection judgment into the inspection report to obtain the quality inspection results of the three-dimensional model;

[0236] For example, in some specific embodiments, first, collect the judgment results (pass / fail / warning), specific descriptions (such as "Hole A diameter out of tolerance 0.1mm"), related parameter values (measured value, standard value) and other inspection results of all inspection items (such as virtual part inspection, hole standard inspection, interference inspection). Mapping association can also be achieved: each result item is associated with a preset "parameter-model element" mapping relationship (such as failure item binding to specific part ID, feature ID or coordinate range).

[0237] In some specific application scenarios, report content can also be dynamically integrated, for example:

[0238] Classification by inspection item: The report shows the results of different inspection items in chapters (such as "1. Inspection check" and "2. Hole standard inspection").

[0239] Aggregation by problem type: classify and count the failed items by dimensions such as "interference problem", "size tolerance", "material violation", etc.

[0240] To explain the principle of the technical scheme of the present application in detail, the overall process of the present application will be described below in combination with some specific embodiments. It is easy to understand that the following is an explanation of the technical principle of the present application and cannot be regarded as a limitation of the present application.

[0241] In view of the related defects and problems of the prior art, the present application provides a three-dimensional model design quality checking method, which performs automatic response checking and result output through preset checking items (including but not limited to virtual part checking, check-in checking, design standard checking, hole standard checking, offset hole checking, missing hole checking, burst hole checking and interference checking). Specifically, as shown in Figure 2 and Figure 3 , it is a specific checking process example for 8 checking items, which can be implemented through the following process:

[0242] 1. Model input and initialization:

[0243] Get the three-dimensional model, and the user loads the three-dimensional model (such as Engine_Block.step) to be checked through import instructions (such as uploading files, PDM system calling, API triggering). The system parses the model data and initializes the checking environment (such as coordinate system, space index construction).

[0244] 2. Extract target parameters on demand:

[0245] Based on the preset checking items, the system extracts parameters according to the user's selected checking items (such as hole standard checking and interference checking, or according to the preset checking order as shown in Figure 2 , the system sequentially traverses the checking logic of each checking item to realize the corresponding checking).

[0246] Example 1 (hole checking): extract hole specifications (diameter, thread type), position coordinates, edge distance, etc.

[0247] Example 2 (interference checking): extract part bounding box and geometric face data for collision detection.

[0248] Mapping relationship establishment: each parameter is bound to a part / feature in the model (such as hole parameter → hole feature ID of part A).

[0249] 3. Sequential checking and interactive confirmation:

[0250] Itemized checking and item-by-item advancement, perform checking according to the preset order (such as: first basic metadata checking, then geometric rule checking, the order of specific checking items can refer to the process shown in Figure 2 ):

[0251] Perform the current check item (e.g. check-in check), verify model designer, material properties, etc.

[0252] Push the result (e.g. "missing material parameters") to the user, wait for user confirmation instruction (click "next step").

[0253] After receiving the confirmation, automatically jump to the next check item (e.g. hole standard check).

[0254] 4. Problem positioning and visual feedback:

[0255] Interactive problem highlighting, user clicks on the failed item in the check report (e.g. "hole H7 position deviation exceeds limit"), triggers selection instruction.

[0256] Based on the preset mapping relationship, the system automatically performs in the three-dimensional view: highlight the problem features (e.g. mark the problem hole in red); focus the view angle and display the label (e.g. "deviation value: 0.15mm > 0.1mm"); isolate related parts (e.g. hide irrelevant parts, highlight the hole and mating parts). Quickly locate the problem, replace manual search.

[0257] 5. Closed-loop correction and result integration:

[0258] Instruction-driven model adjustment, user feeds back model adjustment instruction (e.g. "increase hole diameter from 8.3mm to 8.5mm") according to the highlighted prompt. The system automatically performs parameter modification (calls the kernel API of the relevant software to update the model).

[0259] Correction result backtracking: recheck the corrected item, generate verification result;

[0260] Integrate the original problem, adjustment instruction and corrected result into the final check report to form an audit tracking record.

[0261] In summary, the present application realizes the automation, standardization, objectivity and high efficiency of three-dimensional model design quality check through automatic parameter extraction, logical judgment based on preset rules and result automatic integration report, effectively overcomes the key shortcomings of traditional manual inspection method such as low efficiency, easy to make mistakes, poor consistency, difficult to standardize, tedious report, etc., and provides strong technical support for improving product design quality and research and development efficiency. Compared with the prior art, the present application at least includes the following

[0262] Advantages:

[0263] 1. Greatly improve the efficiency and automation of inspection: By "responding to instructions, automatically extracting target model parameters based on preset inspection items", and "automatically judging based on inspection logic", most of the tedious and repetitive manual measurement and comparison work is completely replaced. The system can quickly process model data, significantly shorten the inspection period, especially suitable for complex models and large batch inspection scenarios, greatly improving the efficiency of the design process.

[0264] 2. Significantly improve the accuracy and consistency of inspection: The "inspection items" and their corresponding "inspection logic" are predefined and fixed in the system, ensuring that each inspection is strictly performed according to the same, objective standard. Eliminate false positives and false negatives caused by human factors (such as negligence, experience differences), output results are highly reliable and consistent, significantly improving the credibility of model quality.

[0265] 3. Standardize and standardize the management of the inspection process: The preset inspection items and inspection logic embody the design specifications and quality standards. The system automatically executes these rules, forcing all models to undergo uniform standard testing, effectively solving the problem of inconsistent rule interpretation and execution, ensuring the uniformity and compliance of design quality.

[0266] 4. Automatically generate structured inspection reports to improve traceability: The process of "integrating the results of inspection judgment into inspection reports" is completely automated. The system can generate clear, structured reports containing specific parameters and judgment results (such as pass / fail, deviation value, problem location marker, etc.). This not only greatly reduces the workload of report preparation, but more importantly, provides complete, objective, and traceable quality records, facilitating problem positioning, responsibility analysis, and quality improvement.

[0267] 5. Efficiently handle complex rules and batch tasks: The system can easily handle inspection items involving multiple parameters and complex logical relationships, and can quickly and accurately complete automated inspection tasks on large batches of models. This makes it possible to implement more comprehensive and in-depth quality inspection, covering areas that were previously difficult for manual inspection.
