[0002] With the rapid development of building information modeling technology, its application in the field of architectural design has become increasingly widespread, greatly improving design efficiency, accuracy and collaboration. The BIM design platform subverts the traditional two-dimensional design method by building a pure three-dimensional design environment, enabling designers to complete architectural design in a highly simulated virtual space. This method not only improves the intuitiveness and comprehensibility of the design, but also promotes information sharing among various disciplines during the design process. However, architectural design is a complex process that is highly dependent on multi-source data, including but not limited to structural analysis, equipment layout, material selection, etc. These data often exist in multiple forms such as two-dimensional drawings, tables, texts, etc., and there is a close correlation and dependence between them. Pure three-dimensional design models have limitations in integrating and processing these complex data, and it is difficult to fully meet the diversified needs of architectural design.

[0003] In order to overcome the limitations of pure 3D design models in BIM design platforms and make full use of the advantages of 2D design, the current architectural design field urgently needs a design method that combines 3D concepts with traditional 2D design. This method should be able to achieve seamless connection and collaborative operation between 2D drawings and 3D models, ensuring the consistency, accuracy and synchronization of design data.

[0023] The embodiments of the present application are further described in detail below in conjunction with the drawings in the specification.

[0024] The embodiment of the present application provides a two-dimensional and three-dimensional collaborative design method based on BIM, which is executed by an electronic device, which can be a server or a terminal device, wherein the server can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides cloud computing services. The terminal device can be a smart phone, a tablet computer, a laptop computer, a desktop computer, etc., but is not limited to this. The terminal device and the server can be directly or indirectly connected via wired or wireless communication, which is not limited in the embodiment of the present application. Figure 1 As shown, the method includes step S101, step S102 and step S103, wherein: Step S101: Acquire a multi-dimensional building data model based on BIM technology, wherein the multi-dimensional building data model is used to simultaneously store building data corresponding to two-dimensional drawings and three-dimensional models.

[0025] For the embodiment of the present application, in order to overcome the limitations of pure three-dimensional design models in the BIM design platform, an innovative design method that can combine three-dimensional concepts and traditional two-dimensional design is proposed. That is, in the two-dimensional and three-dimensional collaborative update platform provided in the embodiment of the present application, both two-dimensional design environments and three-dimensional design environments are provided to designers, so that designers can select a suitable design environment according to the design work requirements. At the same time, the two-dimensional and three-dimensional collaborative update platform realizes the data interconnection between two-dimensional drawings and three-dimensional models, ensuring the synchronous update of building data in two-dimensional and three-dimensional design environments. The collaborative update mechanism helps to reduce building data errors and improve design accuracy.

[0026] Specifically, a multidimensional building data model is pre-stored in the electronic device, and the multidimensional building data model is used to simultaneously store the building data corresponding to the two-dimensional drawings and the three-dimensional model, so that the designer can view the two-dimensional drawings and the three-dimensional model on one platform, avoiding the designer from frequently switching between multiple software, and improving the design efficiency. The construction method for the multidimensional building data model is as follows: obtain the two-dimensional drawings corresponding to the building project, import the two-dimensional drawings into the BIM software, so that the BIM software gradually builds the three-dimensional model, and based on the relevant information of each element in the two-dimensional drawings, define the necessary parameters for each corresponding element in the three-dimensional model, such as size, position, etc., to obtain the three-dimensional model corresponding to the two-dimensional drawings. Then, obtain the multidimensional data storage standard, and according to the multidimensional data storage standard, classify and store the two-dimensional drawings and the three-dimensional model in a high-performance database system to obtain the multidimensional building data model, wherein the multidimensional data storage standard includes but is not limited to: data format, naming rules, metadata definition, etc., to ensure the compatibility and consistency of the two-dimensional drawings and the three-dimensional model at the model level.

[0027] Step S102: performing data association based on the two-dimensional drawings and three-dimensional models stored in the multi-dimensional building data model to obtain a two-dimensional and three-dimensional association relationship.

[0028] For the embodiment of the present application, in order to enable the two-dimensional drawings and the three-dimensional models to be mapped and corresponded to each other and realize the information integration of the two-dimensional drawings and the three-dimensional models, the two-dimensional drawings and the three-dimensional models stored in the multi-dimensional building data model are data-associated, so that the data in the two-dimensional environment and the three-dimensional environment are associated, so as to facilitate the synchronous update of the building data in the subsequent two-dimensional and three-dimensional design environments. There are many specific implementation methods for data association, and the embodiment of the present application is no longer limited. In one feasible method, key elements are identified based on the two-dimensional drawings to determine the first element information, and based on the first element information, elements are matched in the three-dimensional model to determine the second element information; wherein the element types of the first element information and the second element information are objects of design operations in the building project, such as walls, doors, windows, etc.; unique identifier data association is performed based on the first element information and the second element information to obtain a two-dimensional and three-dimensional association relationship; for the unique identifier data association, a data association method of a unique identifier (UUID) is introduced.

[0029] Step S103: A collaborative update mechanism is set based on the two-dimensional and three-dimensional association relationship and the multi-dimensional building data model to obtain a two-dimensional and three-dimensional collaborative update platform so that the two-dimensional drawings and the three-dimensional model perform corresponding update operations to ensure data consistency.

[0030] For the embodiment of the present application, the two-dimensional and three-dimensional collaborative update platform provides designers with both a two-dimensional design environment and a three-dimensional design environment. Setting up a collaborative update mechanism ensures the synchronous update of architectural data in the two-dimensional and three-dimensional design environments, which helps to reduce architectural data errors and improve design accuracy.

[0031] Specifically, the multidimensional building data model stores the building data corresponding to the two-dimensional drawings and the three-dimensional models respectively. The multidimensional building data model supports structured storage, query and modification of data. At the same time, the two-dimensional and three-dimensional association relationship determined by executing data association is: a clear association relationship established between the two-dimensional drawings and the three-dimensional model through a unique identifier. Then, a collaborative update mechanism is set based on the two-dimensional and three-dimensional association relationship and the multidimensional building data model to obtain a two-dimensional and three-dimensional collaborative update platform, that is, an update control mechanism is introduced in the multidimensional building data model to track and record each update of the two-dimensional drawings and the three-dimensional model; and a trigger mechanism is set to respond to the data update operation. When an element in the two-dimensional drawing or the three-dimensional model changes, the trigger mechanism will automatically detect and identify the associated elements associated with it, and trigger the corresponding update operation, so that the changes of the elements on the two-dimensional drawings and the three-dimensional model are consistent, ensuring the consistency of the building data. The 2D and 3D collaborative update platform includes: 2D drawing editing module, 3D model editing module, and data synchronization module. The 2D drawing editing module is used by designers to create and edit 2D drawings, supports standard 2D CAD drawing functions, and can interact with the 3D model editing module for data; the 3D model editing module is used by designers to create and edit 3D building information models, supports parametric modeling and detail editing, and can maintain data consistency with the 2D drawing editing module; the data synchronization module is responsible for real-time monitoring of data changes in the 2D drawing editing module and the 3D model editing module, and through a collaborative update mechanism, ensures real-time and accurate synchronization of data between the 2D drawings and the 3D models.

[0032] It can be seen that in an embodiment of the present application, a multidimensional building data model based on BIM technology is obtained, and the multidimensional building data model is used to simultaneously store the building data corresponding to the two-dimensional drawings and the three-dimensional models. Then, data association is performed based on the two-dimensional drawings and the three-dimensional models stored in the multidimensional building data model to obtain a two-dimensional and three-dimensional association relationship. Finally, a collaborative update mechanism is set based on the two-dimensional and three-dimensional association relationship and the multidimensional building data model to obtain a two-dimensional and three-dimensional collaborative update platform. The two-dimensional and three-dimensional collaborative update platform provides designers with both a two-dimensional design environment and a three-dimensional design environment, so that designers can select a design environment of suitable dimensions according to the needs of the design work. At the same time, setting up a collaborative update mechanism ensures the synchronous update of building data in the two-dimensional and three-dimensional design environments, which helps to reduce building data errors and improve design accuracy.

[0033] Furthermore, in order to improve the accuracy of the building data in the multidimensional building data model and provide designers with intuitive and clear visual feedback, in the embodiment of the present application, it also includes: When a data review instruction is detected, a consistency review of the associated data is performed based on the multi-dimensional building data model and the two-dimensional and three-dimensional association relationships to determine the consistency review result; Based on the difference data in the consistency review results, the differences are marked in the visual views corresponding to the 2D drawings and 3D models, and a consistency review report is generated.

[0034] For the embodiments of the present application, data consistency is crucial in various stages such as building design, construction, operation and maintenance. Inconsistent building data may lead to design errors, construction deviations, cost overruns and other problems. In order to improve the accuracy of building data in the multidimensional building data model, a consistency review of the associated data is performed based on the multidimensional building data model and the two-dimensional and three-dimensional association relationships, and the differences in the two-dimensional drawings and the three-dimensional models are marked, providing designers with intuitive and clear visual feedback, which helps designers quickly understand and process the difference data.

[0035] Specifically, the electronic device pre-stores a data review cycle, that is, each time the data review cycle is reached, the electronic device automatically issues a data review instruction. Therefore, when the data review instruction is detected, the consistency review of the associated data is performed based on the multi-dimensional building data model and the two-dimensional and three-dimensional association relationship to determine the consistency review result, wherein the consistency review result includes: consistent data and difference data. For the consistency review of the associated data, based on the unique identifier in the two-dimensional and three-dimensional association relationship, the two-dimensional elements and the three-dimensional elements with the association relationship are selected from the multi-dimensional building model, and then, the data consistency review is performed based on the two-dimensional elements and the three-dimensional elements to determine the consistency review result, wherein the dimensions of the data consistency review include but are not limited to: geometric shape consistency review, attribute information consistency review, and logical relationship consistency review. For the geometric shape consistency review, by checking whether the outline of the two-dimensional element (for example, the plan view) matches the corresponding section or projection of the three-dimensional element (for example, the three-dimensional model), including: comparison of shape, size, proportion, etc. For the consistency review of the attribute information, verify whether the attribute information of the two-dimensional element and the three-dimensional element is consistent, for example, attribute information such as name, number, type, etc., and the above attribute information is usually used as part of the unique identifier or auxiliary information in the database. For the logical relationship consistency review, check whether the relationship between the two-dimensional elements in the spatial layout is consistent with the actual spatial relationship in the three-dimensional elements, for example, the relative positions of adjacent rooms, the connection relationship of passages, etc.; of course, for architectural models with specific functional areas, verify whether the functional area division in the two-dimensional elements matches the actual division in the three-dimensional elements.

[0036] Furthermore, for the difference data in the consistency review results, the difference data may be architectural data with inconsistent geometric shapes, errors in attribute information, or deviations in spatial relationships. The identified difference data will be used to generate a consistency review report according to predetermined specifications. The consistency review report records the difference location information, difference impact range, difference data, and data correction suggestions, so that designers can quickly locate the data differences and make corrections based on the content of the consistency review report, thereby improving design efficiency and the accuracy of data review. At the same time, based on the difference data in the consistency review results, the difference annotation is performed in the visual view corresponding to the two-dimensional drawing and the three-dimensional model. The difference annotation provides designers with intuitive and clear visual feedback, which helps designers to quickly understand and process the difference data. There are many specific implementation methods for difference annotation. In one achievable method, the annotation type is determined according to the review dimension corresponding to the difference data. For example, for differences with inconsistent geometric shapes, highlighting is used to annotate the differences; for differences with errors in attribute information, abnormal labels are used to annotate the differences. Then, according to the annotation type and difference data, the difference annotation is performed in the visual view corresponding to the two-dimensional drawing and the three-dimensional model.

[0037] It can be seen that in the embodiment of the present application, in order to improve the accuracy of the building data in the multi-dimensional building data model, when a data review instruction is detected, a consistency review of the associated data is performed based on the multi-dimensional building data model and the two-dimensional and three-dimensional association relationship to determine the consistency review result. Then, based on the difference data in the consistency review result, the difference annotation is performed in the visualization view corresponding to the two-dimensional drawing and the three-dimensional model. The difference annotation provides the designer with intuitive and clear visual feedback, which helps the designer to quickly understand and process the difference data and generate a consistency review report.

[0038] Furthermore, in order to enable the two-dimensional drawings and the three-dimensional models to be mapped and corresponded to each other and realize the information integration of the two-dimensional drawings and the three-dimensional models, in an embodiment of the present application, data association is performed based on the two-dimensional drawings and the three-dimensional models stored in the multi-dimensional building data model to obtain a two-dimensional and three-dimensional association relationship, including: Identify key elements based on the two-dimensional drawing to determine first element information, and match elements in the three-dimensional model based on the first element information to determine second element information; Based on the first element information and the second element information, the unique identifier data is associated to obtain a two-dimensional or three-dimensional association relationship.

[0039] For the embodiment of the present application, in order to enable the two-dimensional drawings and the three-dimensional models to be mapped and corresponded to each other and realize the information integration of the two-dimensional drawings and the three-dimensional models, the two-dimensional drawings and the three-dimensional models stored in the multi-dimensional building data model are data-associated, so that the data in the two-dimensional environment and the three-dimensional environment are associated, so as to facilitate the subsequent synchronous update of the building data in the two-dimensional and three-dimensional design environments.

[0040] Specifically, the key elements of the two-dimensional drawing are identified based on the image recognition technology to determine the first element information, which includes but is not limited to: element type, element size, element position, element geometry, and the element may be a building component such as a wall, door, window, beam, or column. The three-dimensional model is parsed to obtain the element information in the three-dimensional model. According to the first element information in the two-dimensional drawing, the three-dimensional model is searched and matched. The matching algorithm can perform matching searches based on multiple factors such as the geometry, position relationship, and attribute characteristics in the first element information, and after finding the element matching the first element information in the two-dimensional drawing in the three-dimensional model, the detailed information of the element is extracted as the second element information. Then, a unique identifier is generated for the first element information in the two-dimensional drawing and the second element information in the three-dimensional model, that is, the first element information and the second element information have the same unique identifier, thereby avoiding the synchronization error of the building data caused by inconsistent element identification. The two-dimensional and three-dimensional association relationship records in detail the corresponding relationship between each first element information in the two-dimensional drawing and the corresponding second element information in the three-dimensional model, and a clear association relationship is established between the two-dimensional drawing and the three-dimensional model through the unique identifier.

[0041] It can be seen that in the embodiment of the present application, in order to enable the two-dimensional drawings and the three-dimensional model to map and correspond to each other and realize the information integration of the two-dimensional drawings and the three-dimensional model, the key elements are identified based on the two-dimensional drawings to determine the first element information, and based on the first element information, the elements are matched in the three-dimensional model to determine the second element information. Then, the unique identifier data is associated based on the first element information and the second element information to obtain the two-dimensional and three-dimensional association relationship, which is helpful for the subsequent synchronous update of the building data in the two-dimensional and three-dimensional design environments.

[0042] Furthermore, in order to enhance the security of building data and prevent unauthorized access and malicious tampering, in an embodiment of the present application, a collaborative update mechanism is set based on the two-dimensional and three-dimensional association relationship and the multi-dimensional building data model, and after obtaining the two-dimensional and three-dimensional collaborative update platform, it includes: Obtain permission level information, restrict access based on the permission level information, and determine data access rules; Add data access rules to the 2D and 3D collaborative update platform. Data access rules are used to control authorized users’ access to building elements to ensure the security of element adjustment. When an adjustment instruction carrying target element information is detected, access permission analysis is performed based on the data access rules and the adjustment instruction. If the access permission is not available, the operation of the adjustment instruction on the target element information is rejected.

[0043] For the embodiment of the present application, after the collaborative update mechanism is set up to obtain a two-dimensional and three-dimensional collaborative update platform, access restrictions are performed based on permission hierarchy information to ensure that only designers with corresponding permissions can access and modify architectural element data, thereby enhancing the security of architectural data and preventing unauthorized access and malicious tampering.

[0044] Specifically, the electronic device pre-stores permission hierarchy information, in which the hierarchy is divided based on position, role, department or project factors, and clarifies the data range and type that each permission level can access and operate. For the specific content of the permission hierarchy information, the user can adjust and set it according to the actual situation. Then, based on the permission hierarchy information, a resource mapping analysis is performed to determine the mapping relationship between the permission hierarchy and the data resources, that is, the data resources that each permission level can access and its operation permissions (for example, read, edit, delete, etc.). Furthermore, based on the mapping relationship between the permission hierarchy and the data resources, the corresponding data access rules are configured, and the data access rules are added to the two-dimensional three-dimensional collaborative update platform to ensure that only designers who meet the permission requirements can access the corresponding data resources, which greatly ensures the security of element adjustment. When an adjustment instruction carrying target element information is detected, the received adjustment instruction is parsed to determine the operation type of the target element information, and the data resource to be accessed is determined in the electronic device based on the target element information, wherein the target element information is a building element in a two-dimensional drawing or a three-dimensional model. Then, based on the mapping relationship between the permission level and the data resource, the existing operation permission of the accessing user on the data resource to be accessed is determined, and a match is performed based on the existing operation permission and the operation type on the target element information. When the match is successful, it indicates that the adjustment instruction has the access permission; when the match fails, it indicates that the adjustment instruction does not have the access permission, and the operation of the adjustment instruction on the target element information is rejected.

[0045] It can be seen that in the embodiment of the present application, access restrictions are performed based on permission level information, and data access rules are determined. Then, the data access rules are added to the two-dimensional and three-dimensional collaborative update platform. The data access rules are used to control the access of authorized users to building elements to ensure the security of element adjustment. When an adjustment instruction carrying target element information is detected, an access permission analysis is performed based on the data access rules and the adjustment instruction. When the access permission is not available, the operation of the adjustment instruction on the target element information is rejected. Setting up access permission analysis ensures that only designers with corresponding permissions can access and modify building element data, which enhances the security of building data and prevents unauthorized access and malicious tampering.

[0046] Furthermore, in order to reduce building data errors and improve design accuracy, in the embodiment of the present application, after performing access rights analysis based on data access rules and adjustment instructions, the following is further included: When the access rights are granted, the associated elements are screened based on the target element information and the two-dimensional and three-dimensional association relationships to determine the associated element information; Based on the adjustment instructions, the target element information and the associated element information are coordinated and adjusted to obtain an updated multi-dimensional building data model, so as to realize the coordinated update of the two-dimensional drawings and the three-dimensional model.

[0047] For the embodiments of the present application, through the real-time collaborative update of two-dimensional drawings and three-dimensional models, designers can share the latest design information on the two-dimensional and three-dimensional collaborative update platform, avoiding duplication of work and communication costs caused by information asymmetry or delays, helping to reduce architectural data errors and improve design accuracy.

[0048] Specifically, when the adjustment instruction has access rights, the associated elements are screened based on the target element information and the two-dimensional and three-dimensional association relationship to determine the associated element information, wherein one of the target element information and the associated element information is a building element on a two-dimensional drawing, and the other is a building element on a three-dimensional model. The data dimensions corresponding to the two element information are no longer limited in the embodiment of the present application, and are determined according to the actual situation of the designer's selection operation. Then, based on the adjustment instruction, the target element information and the associated element information are collaboratively adjusted, that is, the architectural element adjustment performed on the two-dimensional drawing is automatically reflected on the corresponding architectural element in the three-dimensional model, and vice versa, the collaborative adjustment ensures the consistency and accuracy of the design data. For collaborative adjustment, the adjustment logic for the target element and the associated element is determined according to the specific adjustment information in the adjustment instruction, and the adjustment logic includes but is not limited to: modifying the size, moving the position, changing the attribute, etc. Then, based on the adjustment logic corresponding to the adjustment instruction, the adjustment operation is performed on the two-dimensional drawing, for example, modifying the line length, moving the graphic position, changing the attribute annotation information, etc. During the adjustment process, it is ensured that the adjusted two-dimensional drawing still meets the design specifications and drawing standards. At the same time, based on the adjustment logic corresponding to the adjustment instruction, the adjustment operation is performed on the 3D model, such as modifying the geometric shape of the elements in the 3D model, adjusting the positional relationship between elements, updating the element material and texture, etc. Finally, the adjustment results corresponding to the 2D drawings and the 3D model are synchronized to the multidimensional building data model to obtain the updated multidimensional building data model, so as to realize the coordinated update of the 2D drawings and the 3D model.

[0049] It can be seen that in the embodiment of the present application, when the access rights are available, the associated elements are screened based on the target element information and the two-dimensional and three-dimensional association relationship to determine the associated element information. Then, based on the adjustment instructions, the target element information and the associated element information are collaboratively adjusted to obtain an updated multi-dimensional building data model to achieve collaborative updating of two-dimensional drawings and three-dimensional models. The real-time collaborative updating of two-dimensional drawings and three-dimensional models helps to reduce building data errors and improve design accuracy.

[0050] Furthermore, in order for designers to discover and solve potential collision problems in the design stage and optimize the building layout and structure, in the embodiment of the present application, after the target element information and the associated element information are collaboratively adjusted based on the adjustment instruction and the updated multi-dimensional building data model is obtained, the following is also included: Obtain collision detection rules, and perform collision detection on the updated multi-dimensional building data model based on the collision detection rules to determine the conflict area; Provides a visual display based on the conflict area to facilitate the identification of the location of the conflict area.

[0051] For the embodiment of the present application, after the target element information and the associated element information are coordinated and adjusted, collision detection is performed on the updated multi-dimensional building data model, which helps designers to discover and solve potential collision problems in the design stage, so that designers can adjust the design plan in time and optimize the building layout and structure.

[0052] Specifically, collision detection rules are pre-stored in the electronic device, which include different types of detection rules, such as spatial collision detection rules (e.g., conflicts between walls and pipes), functional collision detection rules (e.g., fire escape passages are occupied), and specific detection conditions, judgment criteria, and severity assessment methods are defined for each type of collision. The collision detection rules are determined by technicians based on information from multiple channels such as industry standards, design specifications, and historical project experience. Of course, users can also adjust them according to actual conditions. Then, the updated multi-dimensional building data model is deeply analyzed to extract the coordinated adjustment area, and the collision detection rules are used to identify the conflicts in multiple aspects such as space and function for the elements in the coordinated adjustment area, and the locations where conflicts exist are recorded as conflict areas. Furthermore, visualization technology is used to highlight or specially mark the conflict areas in two-dimensional drawings and three-dimensional models to facilitate the determination of the location of the conflict areas. Of course, an interactive interface can also be provided to allow designers to view the specific conditions of the conflict area and the surrounding building elements in detail through operations such as clicking, zooming, and rotating.

[0053] It can be seen that in the embodiment of the present application, based on the collision detection rules, the updated multi-dimensional building data model is subjected to collision detection to determine the conflict area. The updated multi-dimensional building data model is subjected to collision detection, which helps designers to discover and solve potential collision problems in the design stage, so that designers can adjust the design plan in time and optimize the building layout and structure. Then, a visual display is performed based on the conflict area to facilitate the determination of the location of the conflict area.
