Description

Technical Field

[0001] The present invention belongs to the field of bridge parametric design, and relates to the parametric modeling and output of bridge components using BIM forward design software. Figure 3 The invention relates to a two-dimensional linkage method, especially a two-dimensional linkage bridge parametric modeling, drawing method, device, equipment and medium, which is mainly used in highway, municipal, railway and other bridge fields, and can also be applied to bridge construction, operation management and other fields. Background Art

[0002] With the continuous development of bridge engineering, bridge forms are becoming increasingly complex. Traditional bridge drawing models and quantity counting methods are no longer able to meet the needs of engineering design and construction. For a long time, bridge design has relied on a two-dimensional approach. Engineers manually created drawings using various traditional 2D CAD software, relying on their spatial imagination and design experience to detail key sections of the bridge structure. This approach suffers from a lack of interdependence between drawings. Any local modifications require engineers to manually modify the associated drawings, which is error-prone and inefficient. Furthermore, current bridge design software operates by inputting design parameters to generate 2D drawings. This is also essentially a 2D design method, with drawable freedom limitations. Furthermore, 2D drawings lack visual clarity, requiring engineers to use spatial imagination to examine the bridge structure. With the continuous advancement of computer technology and the widespread application of 3D engineering design techniques, the use of 3D models for design assistance has emerged. However, current 3D modeling requires manual work, resulting in a high output capacity that cannot meet engineering requirements.

[0003] Bridge components are complex, and their design parameters fall into two categories: user-entered parameters and system-calculated parameters. For example, for cast-in-place box girders, the number of user-entered parameters alone can reach over 100. Currently, BIM software creates 3D models based on these design parameters. However, ensuring the accuracy of these parameters (especially those automatically calculated by the system) is a significant challenge. Manually checking the 3D model alone is labor-intensive. Integrating 2D drawings and enabling coordinated 2D and 3D checking greatly simplifies this process.

[0004] According to the survey, the principle of the existing 3D BIM software to generate 2D graphics from 3D components is through projection mapping or 3D section view. Therefore, the principle of 2D drawing generation determines that the drawings can only generate corresponding 2D lines based on their geometric information, which cannot meet the requirements of the bridge drawing specification for the broken representation of components, such as Figure 1As shown in the figure, the pier body and pile foundation of the pier component elevation drawing are too high. If they are all drawn on the drawing, it will take up too much drawing space or even cannot be accommodated. Therefore, they are broken into pieces, which cannot meet the requirements of the specification for layers, colors, line widths, etc. At the same time, for bridge components (such as piers), the drawing method is to combine the same type of components into one drawing. There may be different values ​​of some parameters in this type of components, which are generally marked as parameters on the drawing (such as Figure 1 As shown in the figure, the pier top elevations (H3-H6) in the pier component elevation drawing are then given in a parameter table with specific values ​​for each pier. For more complex upper components, such as cast-in-place box girders with multiple chamfers, simply using sectioning or projection is not enough to generate clear and concise construction drawings.

[0005] Therefore, it is necessary to provide a design method that can simultaneously meet the needs of automatic creation of three-dimensional models of bridge components and generation of two-dimensional drawings, and the two-dimensional drawings and three-dimensional models can realize data linkage, that is, when the parameters are modified on the two-dimensional drawings or three-dimensional models, the models or drawings can be updated synchronously. This can not only give play to the advantages of BIM models, but also make full use of the advantages of clear information and clear markings of two-dimensional drawings, break the barriers between two-dimensional and three-dimensional, and improve the efficiency of design and drawing. Summary of the Invention

[0006] The first purpose of the present invention is to provide a bridge modeling and design method based on component parameterization to address the shortcomings of the existing technology. Figure 3 The 3D linkage method helps engineers efficiently create 3D models of bridge components and generate 2D engineering drawings, improving production efficiency, reducing manpower input and shortening construction period.

[0007] To this end, the above-mentioned purpose of the present invention is achieved through the following technical solutions:

[0008] A two-dimensional and three-dimensional bridge parametric modeling and drawing method includes the following steps:

[0009] S1. Bridge component parameterization step, bridge component parameter input operation, for interactively inputting all parameter information required for bridge component design and providing basic data for bridge design;

[0010] S2, a bridge 3D modeling step based on component parameters, for creating, adding parameters to, and modifying a bridge 3D model according to bridge design parameters;

[0011] S3. Based on the parameterized bridge components and the three-dimensional bridge model, create two-dimensional drawings for defining the drawing information of the upper components, lower components, and auxiliary components, and for generating and modifying two-dimensional drawings;

[0012] S4. The model-drawing linkage modification step based on component parameters is used for real-time modification of components after the parameters of the three-dimensional model and two-dimensional drawings of bridge components are changed.

[0013] Step S1 is the bridge design parameter input step. When component parameters are modified and after steps S2 and S3, the component's 2D drawings and 3D models are automatically updated. In step S1, bridge component parameterization includes creating a bridge component definition and setting its design parameters, modeling parameters, and output parameters. Design parameters include component type, model, fixed size parameters, design standards, and mechanical parameters; modeling parameters include component positioning parameters, component coding, and variable size parameters; and output parameters include output mode, drawing style (fill, pattern, line type, line width, symbol), annotation parameters (style, content, font, height, color), break parameters, and annotation parameters.

[0014] Step S2 includes: generating a three-dimensional model of the bridge component and attaching parameters (S2-1), a sub-step. After step S1 is completed, the operation of step S2 is performed. In step S2, creating the bridge model includes: determining the design standard, engineering grade, and load information of the project based on the bridge design conditions (topography, geology, surrounding environment, and route information), and calling the parametric bridge component of step S1 accordingly. The span combination of the bridge is determined according to the actual project, and the specific model and mechanical parameters of the component to be used are determined; and the positional relationship between the component and the route, and between the components, is determined based on the positioning parameters defined by the component; the variable size parameters of the component instance are calculated by integrating the design conditions, load information, positioning information, and fixed size parameters, thereby determining the design parameters, modeling parameters, and drawing parameters of the placed component instance; generating a three-dimensional bridge model based on the positioning parameters, and attaching the component coding information to the model to complete the creation of the three-dimensional bridge model.

[0015] Step S3 includes four sub-steps: defining the merge drawing rules S3-1, searching all bridge components, merging and classifying them according to parameters S3-2, classifying them into drawings, marking parameters, adding parameters S3-3, and generating a parameter value table for each component S3-4; Step S3 is performed after Step S2 is completed.

[0016] Specifically, the combined drawing rules of the bridge project are defined, the components in the three-dimensional bridge model are grouped according to the drawing rules, and the parameters of the components in each group are counted; for each group of components, the drawing method (sectioning, schematic) to be used when drawing two-dimensional drawings is determined according to the component definition associated with the model; according to the drawing method, the layer, style and other information of the component drawing are determined in combination with the drawing style parameters, and the corresponding annotations are generated according to the annotation parameter information defined by the component, and the corresponding annotation information is generated in combination with the model. At the same time, a table of design parameter information of each group of components is generated; thus, the drawings of the project are generated; the generated two-dimensional drawings have the parameter information of the components, and the two-dimensional drawings are equivalent representations of the three-dimensional components, that is, the two-dimensional graphics of the components are two-dimensional bridge components composed of a combination of lines, annotations, text, etc.

[0017] The merging drawing rules for bridge projects include: there may be a large number of similar components in a single bridge project. According to the requirements of the drawing specifications, similar components need to be merged and grouped according to design parameters, and the components in the same group need to be represented on the same drawing to define the grouping principles; for each drawing category (structural drawing, reinforcement drawing) of each component (upper, lower, and auxiliary), the merging drawing rules are defined separately, and the rules include: but are not limited to the geometric dimensions of the component, the number of elements of the component, the component type, the reinforcement layout parameters, etc. and the combination of various rules; by defining the merging drawing rules, automatic merging is achieved when generating bridge drawings, and the component parameters in the group are summarized to generate a component parameter table.

[0018] The generation of two-dimensional drawings of bridges includes: overall bridge drawing, upper component drawing, lower component drawing and auxiliary component drawing; the drawing methods include: perspective drawing, parametric drawing and schematic drawing; perspective drawing means drawing the component outline based on the three-dimensional model of the component by projection or sectioning, and identifying the visible edges; parametric drawing means reading the instance parameters on the bridge model component and generating the corresponding two-dimensional graphics by drawing; schematic drawing means drawing the component using symbols rather than drawing according to its geometric parameters.

[0019] Step S4 includes two sub-steps: component retrieval S4-1 and component parameter update S4-2. This step is performed after step S2 and step S3 to update the components with corresponding parameters in the model and drawings in real time.

[0020] Step S4 specifically includes two parts: bridge model change-driven update and bridge drawing change-driven update; the design results can be modified on the model and drawings. The model and drawings are associated by adding component coding parameters to the elements, automatically retrieving the corresponding associated design parameters, and modifying the same-coded elements according to the modified parameters; all modification steps are linked and updated, and a modification in one place will be updated everywhere; this process is automatic and does not require manual intervention to ensure data consistency.

[0021] The linked modification step S4 can be invoked multiple times, modifying the results (including 2D drawings and 3D models) from other processes (steps S1, S2, and S3). Multiple iterations are possible, with real-time linkage between data, models, and drawings, significantly improving efficiency. The design process for bridge structures is completed by integrating 2D and 3D design methods.

[0022] The second object of the present invention is to provide a two- and three-dimensional bridge parametric modeling and drawing device to address the deficiencies in the prior art.

[0033] A processor is used to execute the computer program stored in the memory to implement the two-dimensional and three-dimensional bridge parametric modeling and drawing method steps described above.

At the same time, the input parameters, three-dimensional models or two-dimensional drawings can be modified arbitrarily according to the rules. Any modification will trigger the update operation of other related graphics elements, ensuring the consistency of the output results of the model and drawings; at the same time, it greatly facilitates the inspection and verification of design parameters, ensures the correctness of the design results, and realizes true three-dimensional forward design; it has powerful verification functions and real-time dynamic update functions, and can also be applied to the design change process to ensure the consistency of the output results of the model and drawings, providing strong data support for engineering informatization.

[0041] The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

[0042] A method for 2D and 3D linked bridge parametric modeling and drawing includes: a bridge component parameterization step S1, a 3D bridge modeling step S2 based on component parameters, a 2D drawing creation step S3 based on the parametric components, and a model-drawing linked modification step S4 based on component parameters. Specifically, the method is as follows:

[0043] S1. Parameterization of bridge components:

[0044] Parameters include three categories: design parameters, modeling parameters, and drawing parameters. Among them: design parameters include: component type, model, size parameters, design standards, mechanical parameters, and intelligent design parameters; modeling parameters include: component base point parameters, interface parameters, component coding information, and size calculation parameters; drawing parameters include: drawing method parameters, drawing style parameters (fill, pattern, line type, line width, symbol), annotation parameters (style, content, font, font height, color), break parameters, and note parameters.

[0045] Design parameters define information such as the selection criteria, structure, steel strands, reinforcement, and loads for bridge components. Modeling parameters determine the calculation principles, layout methods, and geometric parameters such as the number of components to be laid out based on actual engineering requirements, thereby generating 3D bridge components with engineering properties. Drawing parameters primarily define the component's presentation style in drawings, such as whether the component is drawn broken, symmetrically, and its color, thickness, and size. By defining design parameters, modeling parameters, and drawing parameters, a component's semantic representation is constructed, which can be saved as a template for reuse in a component library.

[0046] S2. Component-Parameter-Based 3D Bridge Modeling: The program generates a 3D spatial model with attribute information based on the semantic representation of bridge components and the current project's engineering information (such as geology, alignment, topography, hydrological conditions, and clearance). Component coding information and design parameters are also added to each component. Users can modify component design parameters, such as pile length and diameter, by clicking on the generated 3D model.

[0047] S3. Generate a 2D drawing of the bridge based on the parameterized bridge components and the 3D bridge model:

[0048] Substep S3-1 primarily defines the rules for merging drawings. When drawing bridge components, merging multiple components is generally necessary. This step primarily defines the criteria for merging components. For example, for substructure drawings, merging criteria include, but are not limited to, structural form, foundation type, and the presence of tie beams. Multiple merging criteria are combined and arranged to calculate the number of drawings to be drawn. Component parameter information is also collected based on the merging principles. Similarly, this information can be saved as a template, which can be used and modified for other bridges.

[0049] The sub-step of step S3-2 mainly searches for all bridge components and classifies them according to parameters. This step is automatically executed. After the 3D modeling operation is completed, the program filters and groups the bridge components according to the drawing rules defined in S3-1.

[0050] Step S3-3 is the step for generating drawings of the lower components, which mainly involves classification into drawings, parameter annotation, and parameter addition. According to the grouping results, the program will express the members of each group on the same two-dimensional drawing by merging the drawings. For components in the same group, for parameters with the same values, the specific values ​​are annotated on the drawing, while for parameters with different values, they are represented in the form of codes and the specific values ​​are given in the parameter table. At the same time, this sub-step performs the parameter addition operation, that is, the design parameters of the components are associated with the two-dimensional graphics elements. The annotation elements of the parameters are parameter-driven graphics elements. When the annotation is double-clicked, the associated design parameters can be modified. When the design parameters are modified, the linkage modification step S4 is automatically triggered.

[0051] The S3-4 sub-step is mainly to generate a table of parameter values ​​for each component.

[0052] S4. Modeling-Drawing Linked Modification: Substep S4-1 primarily involves component retrieval, while substep S4-2 primarily involves component parameter updates. This step, performed after steps S2 and S3, updates the corresponding parameter components in the model and drawings in real time. Once the user generates a 3D model and 2D drawings of a bridge component, the elements in the 3D model and drawings are automatically assigned relevant design parameter information. Users can click on an element in the 3D model or 2D drawing to modify a parameter, and the element is automatically updated. Simultaneously, the program retrieves the relevant 2D and 3D components with this parameter information based on the coded information, automatically updating any retrieved components with this information.
