Description

Technical Field

[0001] The present invention relates to the technical field of drawing update or other related fields, and in particular to a method and device for locking viewport elements of a building information model, and electronic equipment. Background Art

[0002] Today, as building information modeling software is widely used in architectural design and construction, forward drawing has become a standard process for building project documents. General building information modeling software allows users to build three-dimensional models, create and adjust multiple views, and finally integrate these views into drawings to generate accurate construction drawings. However, due to the core feature of building information modeling software - the dynamic link between models and views, once a component is added or modified in the model, all views related to it will automatically update to reflect these changes. At different stages of a design project, engineers and designers often need to maintain multiple views, each of which focuses on a specific part or specific function of the model. For example, in the structural design stage, different views may focus on components such as beams, columns, walls or plates. As the project progresses, new components are constantly added to the model or existing components are modified, and these changes are automatically reflected in all related views. This means that if a view is carefully adjusted during design to highlight a specific component or achieve a specific visual effect, subsequent modifications to the model may destroy these carefully designed layouts, resulting in unnecessary information in the drawings or interference with the original visual focus. Especially in large projects, which usually contain thousands or even tens of thousands of components and hundreds of views, every time a new component is added, the designer needs to check and possibly manually adjust each related view to ensure that the clarity and professionalism of the drawing are not affected. This is not only a time-consuming process, but also prone to omissions, which affects the quality of the drawing and the smooth progress of the project.

[0003] Therefore, in the related art, each time a new object is added to the building information model, the new object will be automatically added to the related view content, resulting in the need to manually hide the new object in the view of each drawing, which is a huge workload and prone to errors.

[0004] To address the above-mentioned problems, no effective solution has been proposed yet. Summary of the invention

[0036] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0037] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0038] It should be noted that the viewport element locking method and device for building information model in the present disclosure can be used in the technical field of drawing update to achieve the locking of drawing viewport elements in building information model.

[0039] The following embodiments of the present invention can be applied to various systems / applications / devices for locking viewport elements in building information models. The present invention avoids the tedious work of designers or engineers manually adjusting each related view after the model is updated by automating the management of the view display content, thereby greatly improving work efficiency and reducing the time for design and document preparation. At the same time, locking the view display content ensures the visual clarity of the design drawings and the consistency of the design intent. Even if new components are added to the model, the locked view will not be disturbed, and its original design layout and visual focus will be maintained.

[0040] The present invention reduces the possible errors and omissions caused by manual adjustment by automatically managing views, improves the accuracy and consistency of drawing information, and reduces the risks in project management. In addition, a user interaction panel is provided, so that users can intuitively view and manage the display status of each view, including lock, unlock and update functions. This not only enhances the user's control over the view content, but also provides the ability to flexibly adjust at different design stages.

[0041] The present invention is described in detail below in conjunction with various embodiments.

[0042] Embodiment 1

[0043] According to an embodiment of the present invention, an embodiment of a viewport element locking method for a building information model is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0044] It should be noted that the embodiments of the present invention can be applied to project design scenarios and construction document preparation scenarios. For example, in the architectural design and drafting stage: when designers are fine-tuning the detailed views of specific design elements, such as elevations, sections or structural details, they often need to ensure that these views will not be affected by subsequent updates of the model. The present invention enables designers to lock the display status of views, so that even if new objects are added to the model, the locked views can maintain their design integrity and will not be disturbed by new objects. When designing large-scale building structures, such as bridges, docks and other projects, multiple views and complex graphics are usually involved. Ensuring that the display status of the graphics in each view meets the design requirements is crucial to generating clear and accurate construction drawings. The present technical solution can effectively manage this process, reduce the tedious work of manually adjusting views due to model updates, save design time and reduce the error rate.

[0045] In addition, during the construction document preparation and project management stage, when the construction team prepares detailed construction drawings, it is necessary to select specific views from the model to display structural details and construction requirements. The locked view display content provided by the embodiment of the present invention can avoid the display of non-related components, ensure that the construction drawings are accurate and easy to understand, and help the smooth progress of the construction process.

[0046] Figure 1 is a flowchart of an optional method for locking viewport primitives for a building information model according to an embodiment of the present invention, such as Figure 1 As shown, the method comprises the following steps:

[0047] Step S101, after detecting that the user terminal completes the drawing operation of the target project using the building information model, extract the drawings, views and graphic elements associated with the target project and list them in the project view list, wherein each view includes at least one graphic element.

[0048] In step S101, after the user completes the drawing operation of the target project using the building information modeling software, the system automatically identifies and extracts all drawings, views (it can also refer to viewports, each drawing includes multiple partial views) and graphic element information associated with the project, and establishes a detailed project view list. It should be noted that the construction of the project view list can be achieved through the FilteredElementCollector function in the software, which can traverse the entire project, filter and collect all relevant drawings and view elements. Each view contains at least one graphic element, which may be a building component, a structural element, a device or any other entity represented in the model. By arranging this information into a list, the system can clearly understand the content of each view and provide data support for subsequent view display content locking operations.

[0049] It should also be noted that in the process of extracting views and elements, the view.IsElementHidden() function can be used to determine the display status of each element in a specific view, that is, whether it is hidden. This step is crucial for subsequent locking and hiding operations because it helps the system determine which elements are visible in the current view and which are manually hidden, so that newly added elements can be accurately identified when the model is updated.

[0050] Optionally, step S101 may include: identifying all drawings of the target project completed using the building information model and the view IDs of each drawing; establishing a first mapping relationship between all drawings and the view IDs of each drawing, and recording the first mapping relationship in the project view list; identifying each view under each drawing and the object primitive ID under each view; for each drawing, establishing a second mapping relationship between each view under the drawing and the object primitive ID under each view, and recording the second mapping relationship in the project view list.

[0051] Among them, identifying all drawings and view IDs can be when using building information modeling software for project design. The system first identifies all drawings associated with the target project and further extracts the IDs of all views under each drawing. The view ID is the unique identifier of the view in the BIM software, through which each view can be accurately located and managed. After that, the system constructs a first mapping table to associate all drawings with their respective view IDs to form a clear hierarchical relationship. This mapping not only helps the system understand the relationship between drawings and views, but also provides convenience for subsequent view management. The mapping relationship is recorded in the project view list to facilitate subsequent queries and operations. Then for each view under each drawing, the system further identifies and records the IDs of all object elements in the view. Object elements include but are not limited to building components, structural elements, equipment, etc. Subsequently, the system establishes a second mapping relationship for the view in each drawing, associates the view with the element ID to manage the display content of each view. This mapping relationship is also recorded in the project view list to provide data support for subsequent view locking and element management.

[0052] Step S102, detecting the content modified by the user end using the building information model, and obtaining a detection result, wherein when an object primitive is added to the building information model, each view displays the object primitive.

[0053] When users use BIM software to modify the model, the system will detect these changes in real time and record the changes, especially when new objects are added to the model. After these changes are captured by the system, corresponding detection results will be generated, which contain information about the new objects. Due to the characteristics of BIM software, once a new object is added to the model, all views related to it will be automatically updated to display the new object. Although this automatic update mechanism ensures data consistency, it can be inconvenient in some cases, especially when it is necessary to keep a specific view layout and content fixed.

[0054] Step S103, when the detection result indicates that a newly added object graphic element to be displayed appears in the building information model, a comparison is made to see whether the newly added object graphic element in the specified view is in the project view list to obtain a comparison result.

[0055] Once the system detects that new objects have been added to the model, it then automatically identifies and compares these new objects. The system checks whether the new objects to be displayed in the specified view already exist in the project view list. For example, the comparison process is completed by analyzing the view ID and element ID, as well as the current display status of the element in the view. If the new object element does not appear in the list, the system will mark it as a "new object element" to be processed.

[0056] Step S104, when the comparison result indicates that the newly added object primitive is not in the project view list, the newly added object primitive to be displayed in the specified view is hidden, and the display content of the specified view is locked.

[0057] When it is determined that there are new objects in a particular view that are not recorded in the project view list, the system will automatically hide the display of these elements in the view, thereby locking the display content of the specified view and keeping its layout and information stable. For example, the hiding operation can be achieved by automatically calling the View.HideElements function in the building information model, which allows the system to hide a specified set of elements and prevent them from appearing in the locked view. After hiding the new objects, the system locks the display state of the view to prevent subsequent model updates from affecting the view.

[0058] When implementing the above functions, the system also provides a user interaction panel, which allows users to intuitively see which views have been locked and which elements are hidden, and allows users to lock and unlock, as well as view and adjust the display status of a single element in each view. In addition, the system also has the ability to unlock and restore synchronization. Users can choose to restore the synchronous update of views and models, so that hidden elements can be displayed again to meet the requirements of design modification or review.

[0059] Through the above steps, after detecting that the user end completes the drawing operation of the target project using the building information model, the drawings, views and elements of the associated target project can be extracted and included in the project view list, wherein each view includes at least one element; the content modified by the user end using the building information model is detected to obtain a detection result, wherein when an object element is added to the building information model, each view displays the object element, and when the detection result indicates that the newly added object element to be displayed appears in the building information model, the newly added object element in the specified view is compared to see whether it is in the project view list to obtain a comparison result, and when the comparison result indicates that the newly added object element is not in the project view list, the newly added object element to be displayed in the specified view is hidden, and the display content of the specified view is locked. In this embodiment, the display status of the view can be locked. Even if new objects are added to the model, the locked view can maintain its design integrity and will not be disturbed by the new objects, thereby ensuring that the display status of the graphics elements in each view meets the design requirements, reducing the tedious work of manually adjusting the views due to model updates, saving design time and reducing the error rate, thereby solving the technical problem in the related art that each time a new object is added to the building information model, the associated view content will automatically add the new object, resulting in the need to manually hide the new object in the view of each drawing, which is a huge workload and prone to errors.

[0060] Optionally, after extracting drawings, views and elements of the associated target project and listing them in the project view list, the method further includes: responding to the project drawing display instruction, controlling the interactive panel to display all drawing lists and project view lists, wherein the drawing list includes all drawings, and the project view list includes: all views and the corresponding elements under each view; receiving a lock operation performed by the user end on the interactive panel, and obtaining a view lock operation output by the interactive panel, wherein the view lock operation is used to lock the specified view.

[0061] It should be noted that the user can send instructions through the interactive panel to request the display of a list of all drawings and a list of project views. In response to this instruction, a list containing all drawings and view information, as well as the display status of all elements under each view, is displayed, providing users with a comprehensive view management interface and an overview of the element display status.

[0062] In addition, the interactive panel provided in this embodiment also has the function of receiving the user's view locking operation. The user can select a specific view to lock, and the system records this operation and controls the display content of the locked view to no longer change with the model update, maintaining its visual and information integrity.

[0063] Optionally, after extracting drawings, views and elements of the associated target project and listing them in the project view list, it also includes: locking all newly added object elements in each view in the drawing, and displaying the locked newly added object elements in the hidden element bar in the interactive panel.

[0064] That is, when the system detects that a new object element has been added to the model, if the element is related to the locked view, the system will automatically hide the newly added element and display the hidden element information in the hidden element column of the interaction panel. This ensures that the display content of the locked view will not be interfered with by the new element, maintaining the clarity and coherence of the design intent.

[0065] Another optional embodiment includes, after hiding the newly added object graphics elements to be displayed in the specified view and locking the display content of the specified view, responding to the unlocking operation of the user end and restoring the object graphics element update function in the specified view; when the newly added object graphics elements appear in the building information model, updating the newly added object graphics elements in the restored specified view, and displaying the newly added object graphics elements in the display graphics element column corresponding to the specified view.

[0066] In this embodiment, the user can restore the dynamic link between the view and the model through the unlock function of the interactive panel, allowing the view content to be updated according to the model. After unlocking, any newly added object primitives will be re-displayed in the view and listed in the display primitive column, intuitively reflecting the latest status of the model.

[0067] Furthermore, the present embodiment can also perform a list display, and the viewport element locking method for the building information model also includes: responding to the panel drawing display instruction, the interactive panel displays a locked drawing list and an unlocked drawing list; responding to the panel view display instruction, the interactive panel displays a locked view list and an unlocked view list; responding to the view element display instruction, the interactive panel displays all elements displayed in the current view and all elements hidden in the current view.

[0068] Among them, when displaying the list of locked and unlocked drawings and views, the system responds to the panel display command, and the interactive panel displays the locked and unlocked drawing lists and view lists. This function allows users to quickly understand which drawings and views are locked and which are still in a dynamic update state. Then the user can use the view element display command to display all displayed elements and all hidden elements in the current view on the interactive panel. This provides users with real-time control over the view display content, making it easy to show and hide specific elements to meet design or review requirements.

[0069] Optionally, the viewport element locking method for the building information model also includes: the visibility status of the object elements corresponding to each view in each drawing is directly related to the number of items in the drawing steel bar schedule, wherein the visibility status includes: hiding the newly added object elements when the specified view is locked, and restoring the display of the newly added object elements when the specified view is unlocked.

[0070] In building information modeling software, the visibility status of the elements in each view of the drawing directly affects the number of items in the drawing reinforcement schedule. When a specified view is locked and the newly added object element is hidden, the number of items related to the element in the schedule will decrease; when the view is unlocked and the newly added element is restored, the number of items will increase accordingly. This association mechanism ensures the consistency of drawing information and reinforcement schedule, which is crucial for construction document preparation and project cost management.

[0071] The above-mentioned embodiment can avoid the problem that designers or engineers need to manually adjust each related view after the model is modified by automatically identifying and hiding the newly added objects, thereby greatly reducing the workload and improving work efficiency. In addition, locking the view display content ensures the visual clarity of the drawing. Even if new components are added to the model, the locked view will not be disturbed, so that the drawing can be more focused on the core information that the designer or engineer wants to express. Furthermore, users can easily manage the display and hiding status of the view through the interactive panel, including locking, unlocking and updating operations, which provides more flexible and sophisticated control means for complex model management. In large projects, due to the dynamic linking characteristics of views and models, manual management of view display content often becomes a bottleneck in project management. The present invention optimizes the efficiency of project document preparation and review by automating this process, and provides an important technical tool for project management.

[0072] Another optional specific implementation is described in detail below.

[0073] The goal of the embodiments of the present invention is to solve the problem that when a new object is added to a model in a general modeling software, the display content of the related views will be added. The specific solution introduces the "view display content custom setting" function, allowing users to lock the display status of the element in the drawing view, thereby avoiding manual resetting after each model modification.

[0074] Figure 2 is a flowchart of an optional method for locking view display content according to an embodiment of the present invention. Figure 2 As shown, including:

[0075] The first step is to extract project drawings, views, and element information and include them in the list.

[0076] In this embodiment, an interactive panel can be provided through TaskDialog for user operation, displaying all drawings (ViewSheet) and view (View) information, allowing the user to view and manage the list of displayed and hidden elements (Elements) in the current viewport.

[0077] In this embodiment, a drawing lock function button may be provided, for example:

[0078] Fi lteredElementCollector: Extract drawings, views, and elements from a project.

[0079] view.IsElementHidden(): Determines whether the element is hidden in the view.

[0080] The second step is to select view lock through the interaction panel.
