[0003] The existing mainstream review method in the industry is still dominated by manual work. After the design is completed, experienced designers or review engineers need to use search tools to find corresponding code provisions, and then manually measure the size in the BIM model, take screenshots and mark the illegal positions, and then summarize the problems to form an Excel or Word report, which is fed back to the designer for modification after secondary proofreading. If the code is updated or the design is changed, the whole review process needs to be re-executed.

DETAILED DESCRIPTION
[0019] In order to make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described in detail below with specific embodiments and corresponding drawings. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.
[0020] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.
[0021] Figure 1 A schematic diagram of the flow of a building code review method for a BIM model provided by an embodiment of the present application. The method can be applied to different business fields. Some input parameters or intermediate results in the flow allow manual intervention to adjust to help improve accuracy.
[0022] The implementation of the analysis method related to the embodiments of the present application can be a terminal device or a server, and the present application does not make special limitations thereon. For the convenience of understanding and description, the following embodiments are described in detail with the server as an example.
[0023] It needs to be pointed out in advance that the present application is based on Revit development.
[0024] Based on this, Figure 1 The flow in the above embodiment can include the following steps: S101: According to the review configuration selection instruction, read the attribute data of the corresponding building component in the target BIM model; the review configuration selection instruction includes a selection instruction of the building component and a selection instruction of the review form.
[0025] In some embodiments of the present application, after receiving the review configuration selection instruction of the user, the residential BIM model to be reviewed, that is, the target BIM model, is opened, and the review type is determined to be a house type review or a building review.
[0026] The building inspection is divided into bathroom inspection, air conditioner site inspection, balcony inspection, and each inspection module is independent of each other. By default, it is selected all, and the designer can cancel the selection of part of the sub-modules.
[0027] Further, in response to the review type selection instruction, attribute data of a corresponding building component in the target BIM model is read, a capital raising stage selection interface is popped up, at least one preset capital raising stage option is displayed, and a capital raising stage confirmation instruction input by a user is received.
[0028] S102: The preset natural language provisions are uniformly formatted and converted to construct a digital review rule.
[0029] In some embodiments of the present application, after receiving the capital raising stage confirmation instruction, the parameter attributes in the target BIM model are determined through the BIM API, and then the specification provisions matched with the capital raising stage are automatically loaded from the specification provision library of the Revit platform according to the parameter attributes. Since the specification provisions are in the form of natural language, they need to be converted into a format recognizable by a computer, and then the format statements are integrated to construct a digital review rule.
[0030] It should be noted that the digital review rule includes a climate division parameter, a component size threshold parameter, a distance threshold parameter, and a material attribute parameter, wherein the climate division parameter covers severe cold regions, cold regions, hot summer and cold winter regions, and hot summer and warm winter regions; the component size threshold parameter covers the minimum size of a washing machine dedicated floor drain and the minimum net height of a balcony railing; the distance threshold parameter includes the maximum allowed distance of 1000mm between the washing machine and the dedicated floor drain and the maximum allowed length of 2000mm of the air conditioner refrigerant pipe.
[0031] The present application extracts the attribute data and component ID of the target component in the BIM model based on the Revit API in batches, and automatically matches and reviews the preset building specification rules, achieving the effect of completing the item-by-item checking of the whole provisions within a few minutes, solving the problem of relying on high-level experts, high labor cost, and long review period in the prior art, and greatly improving the review efficiency.
[0032] S103: According to the digital review rule, the attribute data is logically judged to obtain a rule-violating component.
[0033] In some embodiments of the present application, after obtaining the attribute data and the review rule, the attribute data is logically judged according to the digital review rule.
[0034] When the corresponding building component is a balcony, it is judged whether the corresponding building site of the target BIM model is in a cold region; the cold region is defined according to the corresponding national geographical regulations; In cold regions, the system determines whether a washing machine is present on the open balcony. For example, regulations may stipulate that washing machines cannot be placed on open balconies in extremely cold or cold regions. The system will then retrieve the project information and, if the climate zone is extremely cold or cold, determine whether a washing machine is present on the open balcony. If so, an error message will be displayed, indicating that washing machines should not be installed on open balconies in extremely cold or cold regions.
[0035] If a washing machine is present, the system checks whether a dedicated floor drain and waterproof layer exist within the balcony space, and whether the distance between the floor drain and the washing machine meets a preset threshold. If the threshold is not met, the balcony is identified as an illegal structure. For example, regulations stipulate that when a balcony has washing equipment, the following requirements must be met: dedicated water supply and drainage pipelines and a dedicated floor drain must be installed; both the balcony floor and ground must be waterproofed; in severely cold and cold regions, the balcony should be enclosed and insulation measures should be taken. The system then checks whether the following exists within the balcony space: A_Floor Drain_For Washing Machine, with the family name containing "floor drain" and "washing machine," and the family category: dedicated equipment, detailed item. If not, an error is reported. The error message indicates that a dedicated floor drain for a washing machine is not installed on the balcony.
[0036] For example, when the balcony space includes a washing machine, obtain the washing machine's BoundingBox. Calculate the nearest distance between the center point of A_floor drain_washing machine and the edge of the washing machine's BoundingBox. Determine if the distance is ≤1000mm: if not, report an error. The error message indicates that the washing machine's dedicated floor drain is too far from the washing machine.
[0037] In another example, when the corresponding building component is a bathroom, it is determined whether the bathroom door without an anteroom opens directly into the living room or kitchen. If it opens directly into the living room or kitchen, it is determined to be an illegal bathroom component.
[0038] The review method is as follows: Define a bathroom door: Obtain room A_Bathroom and determine if there is a door family inside the room. If there is a door, this is the bathroom door; otherwise, the door on the room boundary is the bathroom door. Define a kitchen door: Obtain rooms whose names contain "kitchen," and the door on the room boundary is the kitchen door. Define a spatial block: Any wall can be used as a spatial block.
[0039] Furthermore, starting from the origin of washbasin A, draw a straight line along the normal direction of the family, ending at the point where the line intersects any wall. This line can also serve as a spatial divider. Skip this step if there is no washbasin A.
[0040] Define a living room as a room whose name includes "living room" or "sitting room," and find its approximate largest inscribed rectangle. To find the approximate largest inscribed rectangle, obtain all corner points on the room's boundary and pair them up. For each pair of points, obtain their coordinates (x1, y1) and (x2, y2). Calculate the area of the rectangle formed by each pair of points. Sort S from large to small. Judge each S corresponding rectangle whether it is completely located inside the room (i.e. no intersection with the room boundary), if yes, the S corresponding rectangle is the approximate maximum inscribed rectangle. If not, continue to judge the next S until the result is found.
[0041] Then take the origin of the bathroom door family as the starting point, and make a straight line along the normal direction of the family to the space grid as the end point. Judge whether the straight line intersects with the kitchen door or A_living room. If yes, report an error.
[0042] In addition, it is also judged whether the use area of the bathroom with three sanitary equipment meets the minimum area requirement, if not, it is determined as a bathroom illegal component; it is also judged whether the along-wall arrangement space of the sanitary equipment meets the minimum size requirement, if not, it is determined as a bathroom illegal component.
[0043] In another example, when the corresponding building component is an air conditioner site, it is judged whether there is an indoor unit in each independent enclosed space where an air conditioner needs to be set; if there is no air conditioner indoor unit, it is determined as an air conditioner site illegal component; If there is an air conditioner indoor unit, it is judged whether the estimated length of the refrigerant pipe between the air conditioner indoor unit and the corresponding outdoor unit exceeds the preset threshold; if it exceeds, it is determined as an air conditioner site illegal component; it is judged whether the installation position of the air conditioner outdoor unit affects the window opening fan, if it affects, it is determined as an air conditioner site illegal component. The implementation here can be: define the window opening area: get the window opening fan, where the outside of the reference elevation plane, that is, the opening direction of the model line / cross section-solid side, is the window opening side. Then generate an entity shape equivalent to the size of the opening fan in the opening fan part of the window family, as a collision body block. Get the collision body block in the window opening fan family. Get all the window opening areas, judge whether they intersect with A_split air conditioner_outdoor unit and A_door, A_shutter on the air conditioner site. If yes, report an error.
[0044] S104: According to the illegal component, generate a structured review report, and bidirectionally associate the structured review report with the building component of the target BIM model to modify the illegal component; the bidirectional association includes positioning to the corresponding illegal component in the BIM model through the review report.
[0045] In some embodiments of the present application, after obtaining the illegal component, a structured review report is generated according to the illegal component, and the report format includes PDF format and Excel format: the PDF format report contains project name, review date, review type, investment stage, review submodule execution progress statistical chart, and model screenshot of each illegal item (containing highlighted illegal component); the Excel format report contains illegal component ID, review submodule name, illegal reason, specification article number, severity, and processing state (unmodified / modified).
[0046] Further, the application also determines the unique identifier of each component according to the component ID of each component in the constructed target BIM model, and then binds the unique identifier with the item in the review report to realize the bidirectional association and highlight the illegal component in the model interface.
[0047] By establishing the bidirectional association mechanism of illegal component ID and corresponding building code item number, highlighting the illegal component in the Revit interface with preset color, and adding the illegal reason, code source and severity, the effect of double-clicking by the designer to accurately locate the illegal component is obtained, and the problems of model and code separation, manual positioning difficulty and easy misjudgment and omission in the prior art are solved, and the illegal point searching and modification time is reduced.
[0048] S105: According to the received re-examination instruction, incrementally examine the modified illegal component to update the structured review report.
[0049] In some embodiments of the application, after the user modifies the BIM model according to the review report, the user will initiate a re-examination instruction to check whether the modification is comprehensive or there are still errors. After receiving the instruction, the application will incrementally examine the modified illegal component, that is, re-examine the illegal component in the S103 examination step, and update the structured review report after the examination is completed.
[0050] It should be noted that although the embodiments of the application are introduced and described in sequence with reference to Figure 1 steps S101 to S105, this does not mean that steps S101 to S105 must be executed in strict sequence. The embodiments of the application introduce and describe steps S101 to S105 in sequence as shown in Figure 1 in order to facilitate the understanding of the technical scheme of the embodiments of the application by those skilled in the art. In other words, in the embodiments of the application, the sequence of steps S101 to S105 can be adjusted appropriately according to actual needs.
[0051] By Figure 1The method provided by the application extracts attribute data and component ID of a target component in a BIM model in batches based on a Revit API, and automatically matches and checks against preset building specification rules, so that the effect of checking each item of the whole specification within a few minutes is achieved, the problems of the prior art, such as high dependence on high-level experts, high labor cost and long checking period, are solved, and the checking efficiency is greatly improved. By establishing a bidirectional association mechanism of illegal component ID and corresponding building specification item number, the illegal component is highlighted in a preset color in the Revit interface, and the method of adding illegal reason, specification source and severity is adopted, so that the effect of accurately positioning the illegal component by double-clicking of the designer is achieved, the problems of the prior art, such as separation of the model and the specification, difficulty in manual positioning and easy misjudgment and omission, are solved, and the searching and modifying time of illegal points is reduced. By providing a selection function (whole building, house type) at different stages, the effect of adapting to different design requirements and avoiding invalid checking of the whole is achieved, the problems of the prior art, such as lack of pertinence of checking and need to repeatedly perform irrelevant checking steps, are solved, and the pertinence and efficiency of checking are improved.
