[0027] In the technical solution of this invention, engineering drawings are acquired, and the model to be reviewed and the initial model are extracted from the engineering drawings; the model to be reviewed is reviewed based on the initial model, and a review report is generated; based on the review report, the components to be modified in the model to be reviewed are identified and displayed. This method establishes corresponding review rules for each component based on common components and affected components across disciplines. By reviewing the components in the initial model and the model to be reviewed, a review report is generated, realizing a large-scale, automated drawing review method, improving the accuracy and efficiency of the review of the model to be reviewed.

[0028] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification, claims, and accompanying drawings of this invention are used to distinguish similar elements and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms “comprising” or “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0029] For ease of understanding, the specific process of the embodiments of the present invention is described below. Please refer to [link / reference]. Figure 1 The first embodiment of the drawing verification method in this invention includes:

[0030] 101. Obtain engineering drawings and extract the model to be reviewed and the initial model from the engineering drawings;

[0031] In this embodiment, the engineering drawings provided by the designer that need to be reviewed are obtained, and the model to be reviewed and the initial model are extracted from the engineering drawings.

[0032] Specifically, the engineering drawings obtained should include both the model to be reviewed and the initial model. During the cross-disciplinary modification process, based on the common components and affected components between disciplines, the model before modification is the initial model, and the model after cross-disciplinary modification is the model to be reviewed.

[0033] The model to be reviewed and the initial model in the drawings can be placed in any layout page of the engineering drawings, or the initial model can be inserted into the engineering drawings through external reference.

[0034] 102. Based on the initial model, review the model to be reviewed and generate a review report;

[0035] In this embodiment, the components in the initial model are used as the baseline template, and the components in the model to be reviewed are reviewed through different rule descriptions and matching rules between components to generate a review report.

[0036] 103. Based on the review report, identify and display the components to be modified in the model to be reviewed.

[0037] In this embodiment, a report is generated based on the recorded errors, displayed categorized by component and floor, and allows designers to isolate errors for easier modification. Modification permissions for errors are limited to the model to be reviewed. Since the initial model is inserted into the engineering drawings via external references in a linked format, the corresponding components of the errors will also be displayed in the model to be reviewed as reference projection planes.

[0038] In this embodiment, engineering drawings are acquired, and the model to be reviewed and the initial model are extracted from the engineering drawings. The model to be reviewed is then reviewed based on the initial model, generating a review report. Based on the review report, the components to be modified in the model to be reviewed are identified and displayed. This method establishes corresponding review rules for each component based on common components and affected components across disciplines. By reviewing the components in the initial model and the model to be reviewed, a review report is generated, enabling a large-scale, automated drawing review method, improving the accuracy and efficiency of the review of the model to be reviewed.

[0039] Please see Figure 2 The second embodiment of the drawing verification method in this invention includes:

[0040] 201. Obtain engineering drawings;

[0041] In this embodiment, the method of obtaining engineering drawings can be based on an entire project folder. The engineering drawings to be read are located in the document by name. In addition, the project folder should also contain the engineering drawings containing the initial model pointed to by the external link model in step 202.

[0042] 202. Obtain the corresponding initial model based on the external link model;

[0043] In this embodiment, the initial model is inserted into the engineering drawing through an external reference. Because an external reference is used, the initial model cannot be directly obtained from the engineering drawing. It needs to be extracted from the link address provided by the external reference.

[0044] 203. Based on the model drawings, obtain the corresponding model to be reviewed;

[0045] 204. Based on the initial model, the model to be reviewed is reviewed, and a review report is generated;

[0046] 205. Based on the review report, identify and display the components to be modified in the model to be reviewed;

[0047] 206. Based on the review report, determine the structural columns corresponding to the errors in the model to be reviewed and the elements containing doors and windows that have collisions.

[0048] In this embodiment, by determining the error items contained in the review report generated in step 204, the structural columns corresponding to the error items and the doors, windows, or other components recorded in the review report that are involved in collisions are obtained.

[0049] Specifically, in engineering design software, every component, line, symbol, and text must belong to a graphic element. By viewing the properties of a component, you can find the graphic element to which the component belongs, and you can also modify or change the graphic element to which the component belongs.

[0050] Specifically, an error item should be understood as a component or group of components in the initial model and the model to be reviewed that has been modified or contains rule errors. A component group can be understood as a conflict between components that is not permitted by the review rules. Furthermore, the error item should include the corresponding component's ID code, error type, deviation value, and spatial coordinates in both the initial model and the model to be reviewed.

[0051] 207. When any error item in the review report is selected, the remaining elements in the engineering drawings are deselected and locked, and the system jumps to the spatial location of the component to be modified corresponding to the error item.

[0052] In this embodiment, by identifying the graphic element corresponding to the erroneous item, then selecting the remaining graphic elements in the engineering drawing and locking them, the scope of modification is limited to the model to be reviewed that contains the erroneous item. At the same time, since the initial model is displayed in the engineering drawing as an external reference, it will not trigger erroneous modifications.

[0053] In this embodiment, the designer can select any error item in the review report, and the viewport will jump to the component corresponding to the error item after the error item is selected, so as to quickly locate the component to be modified and facilitate the designer to make modifications.

[0054] On the other hand, if the engineering drawings are in multi-viewport mode, when the designer selects any error item in the review report, viewport 1 will jump to the location of the component to be modified corresponding to the error item, and viewport 2 will simultaneously jump to the location of the component to be modified in the initial model.

[0055] Specifically, if the number of viewports is greater than 2, the designer can specify the viewports to jump to. After specifying, by clicking on the error item, the two specified viewports will jump to the spatial coordinates of the initial model corresponding to the error item and the spatial coordinates of the model to be reviewed corresponding to the error item.

[0056] This embodiment, based on the previous embodiment, describes in detail the process of determining the structural columns and door / window elements with collision issues corresponding to errors in the model to be reviewed, based on the review report; when any error item in the review report is selected, the remaining elements in the engineering drawings are deselected and locked, and the process jumps to the spatial location of the component to be modified corresponding to the error item. Compared with the traditional method, this embodiment adds the function of jumping to the component to be modified through the review report, allowing designers to directly jump to the spatial location of the selected error item by selecting an error item in the review report after obtaining the review report and the reviewed engineering drawings, facilitating quick location and modification of the component to be modified.

[0057] Please see Figure 3 The third embodiment of the drawing verification method in this invention includes:

[0058] 301. Obtain the engineering drawings and extract the model to be reviewed and the initial model from the engineering drawings;

[0059] 302. Extract the first bottom surface reference point group of the structural column in the model to be verified and the second bottom surface reference point group of the structural column in the initial model, respectively.

[0060] In this embodiment, steps 302 to 305 will be performed to review the component types of the structural columns in the initial model.

[0061] Specifically, since the layout of structural columns in the component is based on the center point of the bottom surface as a reference, the position matching of structural columns in the model to be checked can be performed using reference points. This is achieved by extracting the first set of bottom surface reference points for the structural columns in the model to be checked and the second set of bottom surface reference points for the structural columns in the initial model. These are then used for the next step of the check rules.

[0062] 303. Compare the spatial positions of the first bottom surface reference point group and the second bottom surface reference point group;

[0063] In this embodiment, structural columns are typically arranged with their base center point as the reference, so spatial point matching can be used for position matching. First, the base reference points of all structural columns in the model to be reviewed are extracted and compared with the base reference points of all structural columns in the initial model. Between these two sets of spatial points, the closest matching point less than a threshold is found, and the structural columns corresponding to this set of points are recorded as a matching group. Since commonly used structural column types are rectangular and circular, the cross-sectional type of each structural column group needs to be determined, and then attribute matching is performed based on the cross-sectional type. The attribute parameters of a rectangular structural column include the instance's position, rotation angle, and cross-sectional length and width; the attribute parameters of a circular structural column include the instance's position and cross-sectional diameter. After comparing the attributes, errors and their corresponding error types are recorded.

[0064] 304. Based on the spatial location, extract the first bottom surface reference point and the second bottom surface reference point that are closest to each other and less than a preset threshold as matching points, and record the structural column corresponding to the matching point as a structural column matching group.

[0065] In this embodiment, the spacing between structural columns can be set to L1. After modification, the adjustment distance of the structural columns in the model to be reviewed can be set to L2. Considering practicality and aesthetics, L1 >> L2. Therefore, it is necessary to preset a distance threshold between L1 and L2, which is included within the adjustment distance of L2 and will not be misjudged as other load-bearing columns.

[0066] On the other hand, there may be situations where the number of load-bearing columns is increased or decreased in the model to be verified due to considerations such as practicality and aesthetics. In this case, it is necessary to determine the differences between the reference points contained in the first bottom reference point group and the second bottom reference point group, and after determining the areas where reference points have been increased or decreased by dividing different regions, these areas are recorded as errors to prevent errors in the region from affecting the verification process of the entire initial model or the model to be verified.

[0067] 305. Compare the attribute parameters of the two structural columns in the structural column matching group, and determine the erroneous items of the structural columns in the model to be reviewed based on the comparison results.

[0068] In this embodiment, since commonly used structural column types are divided into rectangular structural columns and circular structural columns, it is necessary to determine the cross-sectional type of each structural column group, and then perform attribute matching based on the cross-sectional type. The attribute parameters of rectangular structural columns include the instance's position, rotation angle, and cross-sectional length and width; the attribute parameters of circular structural columns include the instance's position and cross-sectional diameter. After comparing the attributes, error items and corresponding error types are recorded.

[0069] 306. Extract the first reference centerline group of load-bearing walls and structural beams in the model to be verified and the second reference centerline group of load-bearing walls and structural beams in the initial model, respectively.

[0070] In this embodiment, the wall arrangement is typically controlled by the centerline, therefore, the position matching of load-bearing walls (since the structural model does not involve operations on non-load-bearing walls, no verification is required) adopts the reference centerline matching method. First, the reference centerlines of all load-bearing walls in the model to be verified are extracted and compared with the reference centerlines of all load-bearing walls in the initial model. Among the two sets of spatial straight line segments, matching straight line segments with the same direction and the closest endpoint distance (determined based on the designer's engineering drawing experience) are found (the length of the straight line segment is not required during the matching stage), and the load-bearing walls corresponding to the straight line segments are recorded as matching groups.

[0071] The placement of structural beams is typically controlled by a centerline; therefore, the position matching of structural beams is done using spatial lines, similar to that of load-bearing walls. After recording the matched structural beams, their attribute parameters include cross-sectional width and height, length, and rotation angle. Errors and their corresponding error types are then recorded after comparison.

[0072] 307. Compare the first reference centerline group and the second reference centerline group, take the first reference centerline and the second reference centerline with the same direction and the closest endpoint distance as the matching straight line segment, and record the load-bearing wall or structural beam corresponding to the matching straight line segment as the reference centerline matching group.

[0073] Specifically, as the reference centerline to distinguish between load-bearing walls and structural beams, the first and second reference centerlines can be marked. During the matching process, only reference centerlines with the same mark can be matched to prevent mismatch of reference centerlines between load-bearing walls and structural beams.

[0074] 308. Compare the attribute parameters of the two load-bearing walls and two structural beams in the baseline centerline matching group, and determine the erroneous items of the load-bearing walls and structural beams in the model to be reviewed based on the comparison results.

[0075] Specifically, the attribute parameters of load-bearing walls include wall thickness, length, and rotation angle. After comparison, errors and their corresponding error types are recorded. The attribute parameters of structural beams include cross-sectional width and height, length, and rotation angle. After comparison, errors and their corresponding error types are recorded. Among the errors, the spatial coordinates of the errors in the initial model and the model to be reviewed should also be recorded, so that the viewport can be adjusted based on the spatial coordinates in the review report.

[0076] 309. Construct the envelope cubes corresponding to the doors, windows, and structural beams in the model to be verified, respectively;

[0077] In this embodiment, due to the objective limitations of current modeling software and computer equipment, in order to save computing resources and time, it is necessary to construct an envelope cube for the doors, windows and structure to replace the actual structural beams and doors for collision detection during the process of checking whether there is a collision after the adjustment of doors and windows.

[0078] Specifically, obvious methods for collision detection of multiple components are very slow. Checking each component against every other component is feasible, but inefficient when the number of components is very large. Checking components with complex geometries in an obvious way, by checking every face against each other, is itself very slow. Therefore, it is necessary to reduce the number of edges and faces of the components, simplifying them into an envelope cube.

[0079] 310. Obtain the spatial position of each envelope cube and determine whether there is a collision event between the spatial positions of the envelope cubes;

[0080] In this embodiment, an envelope cube is constructed for the doors and windows based on their frame thickness, height, width, and location information. Similarly, an envelope cube is constructed for the structural beam based on its length, cross-sectional width and height, and location information. The intersection of these cubes with the door and window envelope cubes is then checked. Upon detection of a collision, the colliding door / window and structural beam, along with their spatial coordinates, are recorded.

[0081] 311. If so, obtain the collision details of the collision event and record the doors and windows that have collision details;

[0082] 312. Summarize the recorded errors and collision situations to obtain a review report;

[0083] In this embodiment, a report is generated based on the recorded errors, displayed categorized by component and floor, and allows designers to isolate errors for easier modification. Leveraging Revit's software features, modification permissions for errors are limited to the model to be reviewed. Since the initial model is projected onto the engineering drawings using external references, the corresponding components of the errors will also be displayed in the model to be reviewed as reference projection planes.

[0084] 313. Based on the review report, identify and display the components to be modified in the model to be reviewed.

[0085] This embodiment, based on the previous embodiment, details the process of verifying the attribute parameters of the structural columns, obtaining and recording errors in the structural columns; verifying the attribute parameters of the load-bearing walls and structural beams, obtaining and recording errors in the load-bearing walls and structural beams; checking the collision status of the doors and windows, and recording the collision status of the doors and windows; and summarizing the recorded errors and collision status to obtain the verification report. Compared with traditional methods, this embodiment refines the verification and recording methods for different components during the drawing verification process. Based on the component classification concept, a system design is implemented, and targeted rule designs are made for the common component categories of the model to be verified and the initial model.
