[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments.

In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0032] This application provides a method for generating elevation drawings based on a BIM model. Figure 1 , which is a schematic diagram of a method flow of an embodiment of a method for generating elevation drawings based on a BIM model of the present application. The method can be executed by an electronic device (eg, a terminal), which can be implemented by software and / or hardware.

[0033] The elevation drawing generation method based on BIM model includes:

[0034] Step S10: Determine the type of the target elevation drawing to be generated by the BIM model;

[0035] Step S20: Read all component coding information of the BIM model;

[0036] Step S30: based on the pre-configured coding database, obtaining the model components corresponding to the coding information of all components;

[0037] Step S40: selecting a target component from the model components according to the type of the target elevation drawing;

[0038] Step S50: Determine a face set of the target component, and generate the target elevation drawing according to the face set.

[0039] Building Information Modeling (BIM) is a model based on digital design and construction. It provides comprehensive construction project management and visual display by integrating information such as the building's geometry, space, structure and materials. The BIM model uses the relevant information data of the construction project as the basis of the model to establish a building model and simulate the real information of the building through digital information simulation.

[0040] An elevation drawing is a graphic used in architectural design to show the appearance and features of the main facade of a building. An elevation drawing is an orthographic projection made on a projection plane parallel to the building's facade. The elevation drawing shows the location and size of the building's exterior, walls, windows, doors, roof and other elements. It is mainly used to show the appearance and aesthetic features of a building, helping people better understand the intent of the architectural design.

[0041] Elevation drawings are usually generated by designers through manual drawing, or with the help of some tools to speed up the process of drawing elevation drawings, but these methods require designers to invest a lot of time in designing these drawings. However, when the BIM model changes, designers need to redesign these drawings. For this reason, this application proposes a method for automatically generating elevation drawings based on the BIM model, aiming to enable users to automatically export elevation drawings when the BIM model changes, without spending a lot of time redrawing the elevation drawings, so as to improve the efficiency of drawing elevation drawings.

[0042] The user (for example, a designer) can open the BIM model through the terminal and select the target elevation drawing to be output through the human-computer interaction interface, that is, the user can select the type of the target elevation drawing to be generated. For example, when the target elevation drawing is a building elevation drawing, the south elevation, north elevation, east elevation, west elevation, etc. can be selected. The user can also select multiple elevations at one time.

[0043] After determining the type of the target elevation drawing to be generated by the BIM model, read all the component coding information of the BIM model. Each component has corresponding coding information. The component can be a building element such as a wall, beam, column, door, window, etc., and each component has corresponding attributes, such as size, material, weight, etc. Since the coding database can store components through the mapping relationship between coding information and components, the model components corresponding to all component coding information can be obtained through the coding database. Specifically, based on the pre-configured coding database, the model components corresponding to all component coding information are obtained, including:

[0044] Parsing each component coding information to determine a target coding matching each component coding information in the coding database;

[0045] The target code is used to obtain a model component corresponding to the component coding information from a data table of the coding database.

[0046] Parse each component coding information, for example, parse out the coding information of the building, floor, and room number in the BIM, determine the target code in the coding database that matches the parsed component coding information, and use the target code to obtain the model component corresponding to the component coding information from the data table of the coding database. For example, the component code in the read model is: CD-XC140-18-07-01-ZW-WLM-TL-001, where the code represents Chengdu-Xinchuan 140-18th Building-7th Floor-01st Room-Master Bedroom-Exterior Facade-Paint-001. By parsing the code WLM-TL, the paint model component can be obtained.

[0047] Due to the difference between design rules and drawing rules, it may not be necessary to use all components of the BIM model, that is, the components used in the generated target elevation drawing are only part of the components of the BIM model. Therefore, the target components can be screened out from the model components according to the type of the target elevation drawing. Specifically, the method of screening out the target components from the model components according to the type of the target elevation drawing includes:

[0048] Determining display rules and design rules of the target elevation drawing according to the type of the target elevation drawing;

[0049] Determining material conditions of components in the design rules;

[0050] Target components that meet the display rules and the material conditions are selected from the model components.

[0051] In addition to the building elevation, the target elevation can also be a color separation elevation, a seam separation elevation, etc., to determine the display rules of the target elevation (for example, if the materials of the components are the same, the colors of the faces are the same) and the design rules (for example, the faces of the same material are merged together). Determine the material conditions of the components required in the design rules, and select the target components that meet the display rules and material conditions from the model components. The target components refer to the components used to generate the target elevation.

[0052] After the target component is screened, a face set of the target component is determined, and a target elevation drawing is generated according to the face set of the target component. Specifically, determining the face set of the target component and generating the target elevation drawing according to the face set includes:

[0053] Acquire all faces of a target component and determine a face set of the target component, wherein the face set includes display information of the target component in the target elevation view;

[0054] Determining the elevation viewing angle of the target elevation drawing according to the type of the target elevation drawing;

[0055] The target elevation drawing is generated according to the elevation viewing angle, the face set and the elevation depth of the target component.

[0056] Get all the faces of the target component to form a face set. For example, if a target component is a cube, the face set of the target component is the six faces of the cube. The face set contains all the display information of the components that need to be displayed in the target elevation view (for example, the surface material of the component, the component type, etc.). According to the type of the target elevation view, determine the elevation view of the target elevation view, for example, the south elevation view, the north elevation view, the east elevation view, the west elevation view, or the elevation view expressed by the axis, etc. The elevation depth refers to the distance in the vertical direction of a face. Each face has a value in the vertical direction. For example, the horizontal projection plane of XY has a Z value for its elevation depth. Since the depth of the elevation describes the extension of the component face in the vertical direction, the target elevation view can be generated according to the elevation view, the face set, and the elevation depth of the target component.

[0057] Further, generating the target elevation view according to the elevation viewing angle, the face set and the elevation depth of the target component includes:

[0058] Obtaining the elevation depth of the target component;

[0059] According to the elevation depth of the target component, sorting each face of the face set to obtain a sorted face;

[0060] A deduplication operation is performed on the sorted faces to generate the target elevation drawing.

[0061] According to the elevation depth of the target component, each face of the face set is sorted from shallow to deep to obtain the sorted faces. Since the sorted faces may be repeated, overlapping, or blocked, it is necessary to perform a deduplication operation on the sorted faces, and generate the target elevation map based on the deduplication-operated faces. Sorting can ensure that the output target elevation map can display the surface information of the component in a certain order, and provide a calculation basis for the merging and deduplication of faces.

[0062] Furthermore, performing a deduplication operation on the sorted faces to generate the target elevation view includes:

[0063] Filtering out duplicate faces or overlapping faces from the sorted faces;

[0064] Performing a merging process on the repeated faces or the overlapping faces to obtain a merged face;

[0065] Deleting the blocked surface from the merged surfaces to obtain the target surface;

[0066] The target elevation map is generated based on the target surface.

[0067] Filter out duplicate or overlapping faces from the sorted faces, and merge faces with the same facade depth. By merging faces, duplicate information can be reduced, as well as the gaps between different faces, making the generated target facade more concise and easier for users to view and understand. Since there may be occluded faces among the merged faces, it is also necessary to delete the occluded faces from the merged faces. For example, if there are walls and windows with different depths after merging, if the window is in front of the wall, the occluded part of the wall will be removed. The remaining faces obtained by deleting the occluded faces are recorded as target faces, and the target facade is generated based on the target faces.

[0068] Further, generating the target elevation image based on the target surface includes:

[0069] A fill color and a fill type are set for the target surface to generate the target elevation view.

[0070] Set the fill type and fill color for the target surface according to the component material. The fill types include gradient fill, texture fill, grid fill, etc., so as to output the target elevation drawings such as building elevation drawings, color separation elevation drawings, and seam elevation drawings. Building elevation drawings are drawings or images showing the facade of a building, used to present the appearance and structure of the building in the vertical direction. Color separation elevation drawings are drawings that distinguish different parts of a building by different colors or shadows based on building elevation drawings. Seam elevation drawings are drawings or images that highlight the gaps or connecting parts of a building based on building elevation drawings. You can also add some annotations to the target elevation drawings, such as elevation, material, etc. You can also add text annotations to the target elevation drawings, including information such as size, material, coordinates, etc. By adding annotation information, you can obtain relevant design drawings for reference during construction and review.

[0071] This application can quickly create building elevation drawings, color separation elevation drawings, seam elevation drawings and other elevation drawings based on the BIM model. After the BIM model design is changed or the model is adjusted, the relevant elevation drawings can be automatically generated according to the adjusted BIM model without having to redraw from scratch, which improves the drawing efficiency and greatly reduces the workload of designers. Designers can focus more on the core parts of creativity and design without spending a lot of time on tedious drawing. The accuracy and consistency of the output elevation drawings can also be ensured.
