Description

Technical Field

[0001] The present invention relates to the technical field of building information modeling, and in particular to a method for extracting a Revit structural line model based on Dynamo, a device for extracting a Revit structural line model based on Dynamo, an electronic device and a computer-readable medium. Background Art

[0002] In the traditional building design and construction process, there are generally three ways to use model analysis and calculation in structural calculation software. The first is to perform modeling and calculation analysis in the structural calculation analysis software. The second is to convert the model format through other BIM software. However, the formats of models established by different software are mostly not universal, and it is necessary to purchase the specific format of the calculation analysis software for conversion. The third and most common method is to export the dwg format by drawing the CAD three-dimensional line model data for calculation analysis. This method is common to almost all structural calculation analysis software.

[0003] Revit is the most commonly used modeling software, but many of the structural models it creates cannot be directly used in structural calculation software such as SAP2000, PKPM, and Yingjianke. They need to be converted into formats through certain specific plug-ins, and there are cases where components are lost after the conversion. Manually drawing the three-dimensional line model of the structure in the Revit model is inefficient, especially for curved components, which have low accuracy and are difficult to draw manually.

[0004] In summary, this method of calculating three-dimensional line form data can meet the needs of structural calculation and analysis except for the case where the workload of depicting the structural model containing curved components is large. Therefore, there is an urgent need for a method to extract the line form information of beams and columns from the Revit structural model, so as to improve the efficiency of structural calculation and analysis in the three-dimensional line form extraction process.

[0061] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0062] Reference Figure 1 , shows a flowchart of a method for extracting Revit structural line formwork based on Dynamo provided in an embodiment of the present invention, which may specifically include the following steps:

[0063] Step 101, running a node package customized in Dynamo software to extract beam and column component information of a Revit model; the beam and column component information includes a family class and a family type name;

[0064] Step 102, extracting geometric position information of beam components and column components in the Revit model; the geometric position information includes the plane positioning XY coordinates of the beam components and column components, the floor elevation of the beam components, the Z-axis offset value of the beam components, and the bottom and top elevations of the column components;

[0065] Step 103, generating beam lines and column lines according to the extracted beam-column component information and the geometric position information of the beam components and the column components, and converting the beam lines and column lines into a beam-column three-dimensional curve model;

[0066] Step 104, check the connection relationship of the generated beam-column three-dimensional curve model in the revit model. After checking and confirming that the connection relationship is correct, export the beam-column three-dimensional curve model in the three-dimensional view as a dwg format file.

[0067] The present invention is based on the method of extracting Revit structural line molds by Dynamo. By running a node package customized in Dynamo software, the beam and column component information in the Revit model can be efficiently and accurately obtained. This information can include basic attributes such as family and family type name, and Dynamo nodes are added and configured to extract the geometric position information of beam components and column components, including the plane positioning XY coordinates of beams and columns, floor elevations, Z-axis offset values, and the bottom and top elevations of columns, etc. The extracted information is further used by Dynamo nodes to generate beam lines and column lines, and these beam lines and column lines are converted into three-dimensional curve models. The generated three-dimensional curve model is then checked for connection relationships in the Revit environment to ensure that the connections between all structural elements are correct. Once the connection relationship is confirmed to be correct, these three-dimensional curve models can be exported as dwg format files in a three-dimensional view, which is convenient for integrated use with other structural calculation software, and promotes the seamless connection of the design process.

[0068] The method of the present invention greatly simplifies the data preparation process from the Revit model to other structural calculation software. Traditionally, this process may require manual input or conversion of data, which is error-prone and time-consuming. However, by using a node package customized in Dynamo and adding configured Dynamo nodes, automated information extraction and processing can be achieved, greatly improving work efficiency and reducing the possibility of human error. Since all necessary information is extracted directly from the Revit source file, the high accuracy of the generated three-dimensional curve model in size and spatial position is ensured. Finally, the processed beam-column three-dimensional curve model is exported as a dwg format file, which is convenient for seamless integration with other structural calculation software and promotes cross-platform collaboration. A connection relationship check step is added before exporting to ensure that the understanding relationship between all beams and columns is correct, thereby enhancing the consistency and reliability of the entire structural system.

[0069] In one embodiment of the present invention, extracting geometric position information of beam components and column components in a Revit model includes:

[0070] Add and configure the Element.GetLocation node to extract the plane positioning XY coordinates of the beam component in the Revit model, the floor elevation of the beam component, and the plane positioning XY coordinates of the column component;

[0071] Add and configure the Element.GetParameterValueByName node to extract the Z-axis offset value of the beam component and the bottom and top elevations of the column component in the Revit model.

[0072] In order to accurately extract the geometric position information of beam and column components in the Revit model, the present invention adds and configures the Element.GetLocation node, which is specifically used to capture the plane positioning XY coordinates of the beam and column and the floor elevation. At the same time, the Element.GetParameterValueByName node is added and configured to extract the Z-axis offset value of the beam and the bottom and top elevations of the column. The application of these two nodes ensures a comprehensive understanding of the spatial position of the beam and column components in the model, thereby improving the accuracy of generating a three-dimensional curve model.

[0073] In one embodiment of the present invention,

[0074] Add and configure the Element.GetLocation node to extract the plane positioning XY coordinates of the beam component in the Revit model, the floor elevation of the beam component, and the plane positioning XY coordinates of the column component, including:

[0075] Add and configure the Element.GetLocation node to extract the plane positioning XY coordinates of the beam components in the Revit model and the floor elevation where the beam components are located, and use the CodeBlock node to extract the plane positioning XY coordinates of the column components in the Revit model;

[0076] Add and configure the Element.GetParameterValueByName node to extract the Z-axis offset value of the beam component and the bottom and top elevations of the column component in the Revit model, including:

[0077] Add and configure the Element.GetParameterValueByName node, and use the CodeBlock node to extract the Z-axis offset value of the beam component in the Revit model, the floor elevation and Z-axis offset value of the bottom and top of the column component;

[0078] Add and configure the Element.GetParameterValueByName node, use the CodeBlock node to expand the elevation of the floor where the bottom and top of the column are located, and use the "+" node to superimpose the floor elevation of the bottom and top of the column with the Z-axis offset value to generate the bottom and top elevations of the column.

[0079] This embodiment refines the method of obtaining the plane positioning XY coordinates of the beam component and the floor elevation thereof through the Element.GetLocation node, and adopts the CodeBlock node to obtain the plane positioning XY coordinates of the column component.

[0080] At the same time, this embodiment also describes in detail how to use the Element.GetParameterValueByName node to extract the Z-axis offset value of the beam component and the bottom and top elevations of the column component in the revit model. Specifically, the CodeBlock node is used to extract the Z-axis offset value of the beam component, as well as the floor elevation and Z-axis offset value of the bottom and top of the column component. By superimposing the floor elevation and Z-axis offset value of the bottom and top of the column component through the "+" node, the accurate elevation of the bottom and top of the column component can be generated, ensuring that the size and position of the generated three-dimensional curve model in the vertical direction are also accurate, providing reliable guarantee for subsequent structural analysis.

[0081] In one embodiment of the present invention, beam lines and column lines are generated according to the extracted beam-column component information and the geometric position information of the beam components and the column components, and the beam lines and column lines are converted into beam-column three-dimensional curve models, including:

[0082] Use the geometry node to perform geometric transformation on the plane positioning XY coordinates of the beam component, the floor elevation of the beam component, and the Z-axis offset value of the beam component to generate the beam line, and use the ModelCurve.ByCurve node to convert the beam line into a three-dimensional curve model of the beam;

[0083] Use the Point.ByCoordinates node to connect the plane positioning XY coordinates of the column component with the bottom and top elevations of the column component to generate the bottom spatial coordinates of the column component and the top spatial coordinates of the column component. Use the Geometry.Line.Create node to generate the column line for the bottom spatial coordinates of the column component and the top spatial coordinates of the column component, and use the ModelCurve.ByCurve node to convert the column line into a column three-dimensional curve model.

[0084] In the process of generating beam lines and column lines, the present invention uses the geometry node in Dynamo to perform geometric transformation on the plane positioning XY coordinates, the floor elevation and the Z-axis offset value of the beam component to generate the beam line, and uses the ModelCurve.ByCurve node to convert it into a three-dimensional curve model, thereby realizing the accurate representation of the beam component in three-dimensional space.

[0085] For column components, first use the Point.ByCoordinates node to generate the corresponding spatial coordinate points based on their plane positioning XY coordinates and the bottom and top elevations, and then connect these points through the Geometry.Line.Create node to form a column line. Finally, use the ModelCurve.ByCurve node to convert the column line into a three-dimensional curve model, achieving accurate representation of the column component in three-dimensional space and connection with the beam component.

[0086] In one embodiment of the present invention, a connection relationship check is performed on the generated beam-column three-dimensional curve model in the revit model. After the connection relationship is checked and determined to be correct, the beam-column three-dimensional curve model is exported in the three-dimensional view as a dwg format file, including:

[0087] Check in the Revit model whether the intersection of each beam-column node in the generated beam-column 3D curve model is connected;

[0088] If there are any unconnected intersections of beam-column nodes, the user will be reminded to close the unconnected intersections of beam-column nodes.

[0089] After checking and confirming that the connection relationship is correct, export the beam-column 3D curve model in the 3D view as a dwg format file.

[0090] After the generation of the beam-column three-dimensional curve model is completed, the present invention emphasizes the importance of connection relationship checking. In the Revit model, it is necessary to ensure that each intersection of the beam-column node has a correct connection. To this end, the beam-column connection relationship is automatically checked through this embodiment. When unconnected beam-column nodes are found, the user can be reminded to take measures to close these nodes to ensure the integrity of the structure. Once all connection relationships are verified and confirmed to be correct, these three-dimensional curve models can be exported as dwg format files.

[0091] The following is a complete process of designing the method of extracting Revit structural line formwork based on Dynamo of the present invention:

[0092] (1) Open Dynamo software and create a new script file;

[0093] (2) Create a custom node in the Dynamo interface. This node is mainly used to automatically obtain the information of beam and column components in the model (family category, family type name). Edit the node and complete the input, packaging, and publishing of the custom Python node package code. The Python code is as follows: Figure 2 As shown, the node is located at the initial end of the process, such as Figure 3 and Figure 4 As shown in process a;

[0094] (3) Add and configure the Element.GetLocation node and connect process a and process b, where:

[0095] 1) Extract the plane location of the beam component and the floor elevation where it is located, such as Figure 3 As shown in process b;

[0096] 2) Extract the plane positioning and floor elevation of the column component. Since the column component has bottom and top coordinates, and the default floor elevation obtained by this node is zero, a CodeBlock node is added here to extract the XY coordinates of the column plane positioning. The floor elevations of the bottom and top of the column need to be retrieved from other steps. Here, only the plane XY coordinates are extracted, such as Figure 4 As shown in process b;

[0097] (4) Add and configure the Element.GetParameterValueByName node and connect step a and step c, where:

[0098] 1) Extract the parameter value of the beam component: Use the CodeBlock node to obtain the Z-axis offset value parameter of the beam, such as Figure 3 As shown in process c;

[0099] 2) Extract the parameter values ​​of the column components: Since step (3) cannot obtain the floor elevation and Z-axis offset value of the column, it is necessary to repeat the node here to obtain it. Use the four parameters of two sets of CodeBlock nodes to obtain the floor elevation and Z-axis offset value parameters of the bottom and top of the beam column respectively, such as Figure 4 As shown in process c; add an Element.GetParameterValueByName node, use the CodeBlock node to expand the elevation of the bottom and top of the column obtained in process c, and finally use the "+" node to superimpose the floor elevation of the bottom and top of the column with the Z-axis offset value to generate the elevation of the bottom and top of the column, as shown in Figure 4 As shown in process c and f;

[0100] (5) Beam curve generation: Use the geometry node to perform geometric transformation on the beam information extracted in the above steps to generate beam lines, such as Figure 3 As shown in process d, the ModelCurve.ByCurve node is finally used to convert the beam line into a three-dimensional curve model, such as Figure 3 As shown in process e;

[0101] (6) Generate the column spatial coordinates: Use the Point.ByCoordinates node to connect the column plane positioning coordinates of process b with the column bottom and top elevations obtained in process f to generate the column bottom spatial coordinates and column top spatial coordinates, such as Figure 4 Process g is shown as follows:

[0102] (7) Finally, use Geometry.Line.Create to generate the column line, and use the ModelCurve.ByCurve node to convert the column line into a three-dimensional curve model;

[0103] (8) Check the generated structural line form in the Revit model to see if the connection relationship is correct, and ensure that each beam-column node intersection is connected. Unsatisfactory nodes need to be closed manually, and finally export the DWG format in the 3D view, such as Figure 5 shown.

[0104] It should be noted that, for the sake of simplicity, the method embodiments are described as a series of action combinations, but those skilled in the art should be aware that the embodiments of the present invention are not limited by the order of the actions described, because according to the embodiments of the present invention, certain steps can be performed in other orders or simultaneously. Secondly, those skilled in the art should also be aware that the embodiments described in the specification are all preferred embodiments, and the actions involved are not necessarily required by the embodiments of the present invention.
