[0044] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0045] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0046] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0047] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0048] See also Figure 1 , Figure 1 A schematic flow chart of a BIM modeling method based on an IFC component template according to an embodiment of the present application is shown.

[0049] like Figure 1As shown, according to an embodiment of the present application, a BIM modeling method based on an IFC component template is used in a BIM modeling system based on an IFC component template, and the process includes:

[0050] Step S101, receiving an inputted new creation instruction for a target project model, wherein the new creation instruction includes a target IFC component name;

[0051] In this step, the BIM modeling system based on the IFC component template can be an APP. When the user wants to create a new target project model, a new option can be displayed on the APP page. After the project model is created, the IFC component can be created in the project model. Specifically, Figure 2 As shown, when an input instruction for creating a target project model is received, the name of the target project model can be added to the project information, and under the target project model, the IFC component to be created can be added.

[0052] Step S102, according to the creation instruction, obtaining a corresponding target IFC component from the IFC component library, and outputting parameter setting prompt information corresponding to the target IFC component;

[0053] like Figure 2 As shown, when an input instruction for creating a target project model is received, the target project model name can be added to the project information. Under the target project model, the IFC component to be created can be added. After selecting the target IFC component, the system will output corresponding parameter setting prompt information to prompt the user to perform corresponding parameter settings, such as component parameter information corresponding to the target IFC component, including but not limited to the spatial position, geometric dimensions, point layout, etc. of the component.

[0054] Step S103, receiving component parameter information corresponding to the parameter setting prompt information, and generating and outputting a corresponding final IFC component according to the component parameter information;

[0055] In one embodiment, optionally, the component parameter information includes at least one of the following:

[0056] Component shape information, component spatial position information, component attribute information, component geometric size information and component point layout information.

[0057] In this embodiment, the component parameter information includes spatial position information, such as three-dimensional coordinates, X-axis, Y-axis and Z-axis directions, etc., and also includes the shape, properties, geometric dimensions and point layout of the component.

[0058] like Figure 3As shown in the figure, in the IFC standard, the sixth attribute of each component is the spatial location attribute ObjectPlacement (the sixth attribute of each component is the spatial location attribute ObjectPlacement), which directly indexes IfcLocalPlacement. The second attribute of IfcLocalPlacement, RelativePlacement, is the index of the three-dimensional coordinate point, that is, IfcAxis2Placement3D. The first attribute Location of IfcAxis2Placement3D is the three-dimensional coordinate (x, y, z), which points to IfcCartesianPoint.

[0059] Setting the coordinates of the component in the component information template will directly modify it in IfcCartesianPoint to achieve the setting or modification of the IFC file.

[0060] When filling in a corner, you need to rotate the component according to the corner and modify the relevant data and fill it into the IFC file.

[0061] The rotation angle information is also in IfcAxis2Placement3D mentioned above, which is the second attribute Axis (representing the z-axis direction) and the third attribute RefDirection (representing the x-axis direction) of IfcAxis2Placement3D, both pointing to IfcDirection. The Y-axis direction is calculated from the x-axis direction and the z-axis direction by the right-hand rule, and is calculated by the vector product, that is, y=z×x.

[0062] Analyze the transformation matrix after rotation around different axes.

[0063] Rotation around the z-axis / X0Y plane rotation: The component rotates around the z-axis, the z-axis remains unchanged, and the directions of the x-axis and y-axis change, that is, the converted coordinate axes are as follows:

[0064]

[0065] Example: If the rotation angle around the z axis / X0Y plane is 30°, the new coordinate vector is

[0066] Set the original X, Y, and Z axis vectors to x = (0, -1, 0), y = (1, 0, 0), and z = (0, 0, 1);

[0067]

[0068] Rotation around x-axis / Y0Z plane rotation: The component rotates around the x-axis, the x-axis remains unchanged, and the directions of the Z-axis and Y-axis change.

[0069]

[0070] Rotation around y axis / Z0X plane rotation: The component rotates around the y axis, the y axis remains unchanged, and the directions of the X axis and Z axis change.

[0071]

[0072] After obtaining the new coordinate direction, you need to add IfcDirection statements for the z-axis and the x-axis in the IFC file to bind the new direction vector IFC data to the component.

[0073] In the IFC standard, there are a large number of geometric entities that express different component geometric dimensions. Take the geometric dimension settings of a rectangular component as an example:

[0074] The geometric shape of a cuboid component is generally formed by stretching a rectangular section along a certain direction to form a solid. First, index the geometric expression entity IfcExtrudedAreaSolid of the component. The specific index path is as follows: the seventh attribute Representation of the component IFC entity points to Items of IfcProductionRepresentation and IfcShapeRepresentation, and then points to IfcExtrudedAreaSolid.

[0075] The fourth property of IfcExtrudedAreaSolid points to the cross-sectional dimensions. The IFC statement in the figure above is a rectangular IfcRectangleProfileDef. You can also set different cross-sectional shapes such as circular IfcCircleProfileDef and C-shaped IfcCShapeProfileDef. The dimensions of other cross-sectional dimensions are also defined using geometric eigenvalues.

[0076] The fourth attribute (XDim) and fifth attribute (YDim) of IfcRectangleProfileDef are the length and width of the section respectively. The length of the component is determined by the extruded length (the fourth attribute Depth) of IfcExtrudedAreaSolid.

[0077] Considering that there may be a large number of components of the same type in an engineering project, the platform supports batch creation of components, which greatly improves modeling efficiency. By setting the point layout rules of multiple components, component models are created in batches through matrix layout. The default is 1 component. The directions along the x-axis, y-axis, and z-axis are the directions of the entire project.

[0078] In this embodiment, a project template for a new model is selected, and appropriate IFC components are loaded for modeling. Before loading into the project, component-related parameters are input, including spatial position, geometric dimensions, etc. The platform automatically generates corresponding components according to the set parameters and deploys them on the specified spatial coordinates, thereby realizing template-driven modeling.

[0079] Step S104: assemble all the final IFC components to generate a target BIM model corresponding to the target project model.

[0080] In this embodiment, according to the project requirements, components of different professions are loaded and assembled to form a project BIM model.

[0081] In one embodiment, optionally, the method further comprises:

[0082] The target BIM model is stored in an IFC format.

[0083] Traditional BIM modeling methods are mainly implemented in commercial software, which is a private BIM model format of software manufacturers. The present invention uses a component model in the IFC format to create a project BIM model, which can be connected to different software or platforms to achieve data interconnection.

[0084] By implementing BIM modeling based on IFC components, components in other software formats can be exported to IFC format. Through a uniformly set parsing and expansion mechanism, IFC components that meet the requirements of this solution can be formed. The number of components can continue to grow to meet the modeling of different types of projects, with strong scalability.

[0085] In one embodiment, optionally, the method further comprises:

[0086] Receive input component code configuration template setting instructions;

[0087] According to the component code configuration template setting instruction, the corresponding component code configuration template setting is performed, wherein the component code configuration template includes an IFC entity, a component type, a component name and a code.

[0088] In this embodiment, if Figure 4 As shown, the component coding configuration template includes IFC entity, component type, component name and code, etc.

[0089] Compared with BIM modeling of traditional commercial software, whose model architecture is highly arbitrary and difficult to match with the component system of standard specifications, this solution studies and formulates standardized coding configuration templates. While meeting the coding settings of different coding methods, the BIM model is built according to the classification coding system, and the classification level is clearer and more reasonable. Based on the configuration template, the mapping mechanism with IFC semantic data is realized, providing technical support for the automatic indexing of coded entity objects. The creation of BIM models is directly driven by parametric templates, which is more accurate and efficient.

[0090] In one embodiment, optionally, the method further comprises:

[0091] Get standard IFC components;

[0092] According to the component coding configuration template, matching the corresponding component classification unique code for the standard IFC component;

[0093] According to IFC standard rules, the attributes corresponding to the component classification unique codes are associated with the standard IFC components to generate the IFC component library.

[0094] In this embodiment, if Figure 5 As shown, standard IFC components are imported, and the component classification unique codes are automatically matched according to the component coding configuration template, and the classification coding attributes are written into the components according to the IFC standard rules, so as to uniformly manage and store the components.

[0095] In one embodiment, optionally, the method further comprises:

[0096] Receive input component editing instructions;

[0097] According to the component editing instruction, a corresponding editing operation is performed on the component in the IFC component library.

[0098] In this embodiment, the components in the IFC component library can be managed, for example, editing operations can be performed, and the editing operations include but are not limited to operations such as adding, modifying, deleting and querying, so as to meet different usage requirements of different users.

[0099] In one embodiment, optionally, the component parameter information further includes: timestamp information corresponding to the component;

[0100] The method further comprises:

[0101] receiving input schedule simulation instructions of a target project model;

[0102] According to the progress simulation instruction and the timestamp information, a corresponding project progress simulation is performed on the target project model.

[0103] In this embodiment, when setting component parameters, specific timestamp information may also be added, so that the project progress may be simulated based on the timestamp information, thereby facilitating users to understand the project progress.

[0104] In summary, if Figure 6 As shown, the specific process of the BIM modeling method based on the IFC component template according to an embodiment of the present application includes:

[0105] Develop standardized component coding configuration templates for management and persistent storage.

[0106] The platform imports IFC standard components, automatically matches component classification unique codes according to coding templates, and writes classification coding attributes into components according to IFC standard rules, so as to uniformly manage and store components.

[0107] Select the project template for the new model, load the appropriate IFC components for modeling, and input component-related parameters, including spatial position, geometric dimensions, etc., before loading into the project. The platform automatically generates corresponding components based on the set parameters and deploys them on the specified spatial coordinates, thereby realizing template-driven modeling.

[0108] According to project needs, components of different disciplines are loaded for assembly to form a project BIM model, which is stored in IFC format.

[0109] Through the above technical solution of the present invention, based on the component library of BIM general data format IFC and based on the classification coding standard specification, a classification system for various facilities and equipment in the BIM component library is established. Using the infrastructure equipment of various professions in the BIM component library, through the component template bound to the IFC data, the component model is directly placed in the three-dimensional view to achieve modeling in a driven manner, eliminating the complex modeling process of the component itself, and improving the modeling efficiency and standardization.
