Description

Technical Field

[0001] The present invention relates to the technical field of BIM modeling, and in particular to a Revit-based parametric modeling method for a horse head door. Background Art

[0002] BIM forward design uses the three-dimensional model as the starting point and data source to complete the entire process from scheme design to construction drawing design. It can detect the rationality of the design in real time, ensure the accuracy of building information data, and provide guarantees for subsequent applications in various aspects such as construction and operation and maintenance.

[0003] Autodesk Revit is one of the most mainstream BIM applications in the industry and is widely used in BIM design projects. Modeling of door sills in Revit typically requires engineers to manually create different door sill families based on project requirements and door sill drawings. Complex door sills can be time-consuming. For projects with tight deadlines and a wide variety of door sill styles, traditional modeling methods not only consume significant manpower and time, but also significantly impact project design efficiency. Summary of the Invention

[0004] The present invention is made to solve the above technical problems, and its purpose is to provide a parametric modeling method of horse head doors based on Revit, which can improve the modeling efficiency of horse head doors in projects.

[0005] In order to achieve the above object, the present invention provides a parametric modeling method of a horse head door based on Revit, comprising the following steps:

[0006] S1. Collect basic information of all gates from the design plan of the target project, including gate type, gate size, gate location information and support materials;

[0007] S2. Based on the basic information, create parameters of different family types to form a shared parameter file;

[0008] S3. In Revit software, locate the spatial position of any type of horse-head door model, establish a reference plane, use dimensioning and alignment functions to associate the physical outline of the current type of horse-head door with the reference plane, and use the shared parameter file to quickly establish and control the parameters of each current type of horse-head door in the target project, thereby forming models of all horse-head doors under the current type of horse-head door;

[0009] S4. Repeat step S3 until the modeling task of each horse head door under all types of horse head doors in the target project is completed.

[0010] As described above and in practice, the Revit-based parametric modeling method for horse-head doors described in this invention associates the physical outlines of horse-head doors with reference planes. Once a model for one type of horse-head door is created, models of other sizes of horse-head doors within that type can be created simply by modifying the shared parameter file within the model. Compared to independently creating individual horse-head door models, this method significantly improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, the exemplary embodiments can be embodied in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concepts of the exemplary embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0016] In this embodiment, a parametric modeling method of a horse head door based on Revit is disclosed for accurately controlling the grouting process. Figure 1 As shown in the figure, the parametric modeling method of the horse head door based on Revit mainly includes the following steps:

[0017] Step S1: from the design plan of the target project, collect the basic information of all the gates, including the type of gate, size of gate, location information and support materials.

[0018] In a specific embodiment, horsehead gate types include double-sided flat-top horsehead gates, double-sided sloping-top horsehead gates, and single-sided horsehead gates. Horsehead gate dimensions include tunnel length, tunnel wall height, tunnel net width, tunnel support thickness, tunnel floor thickness, shaft length, shaft net diameter, and shaft wall thickness. The tunnel length includes variable-section tunnel length and constant-section tunnel length. The tunnel wall height includes constant-section tunnel wall height and variable-section tunnel wall height. The variable-section wall height includes minimum and maximum wall heights. Support materials include concrete, shotcrete, anchor rods, and anchor cables.

[0019] Step S2: Based on the basic information, create parameters of different family types to form a shared parameter file.

[0020] In one embodiment, creating different family type parameters and forming a shared parameter file specifically includes the following steps:

[0021] Step S21: classify the basic statistical information according to the type, size, positioning information and support material of the horse head gate and record it in an Excel table;

[0022] Step S22: Name the basic information of the Excel record, and the name is consistent with the parameterized name;

[0023] Step S23: Complete the creation of a shared parameter file in the Revit software label based on the named name.

[0024] Through these two steps, the detailed parameters of all types and specifications of horse head doors in the target project can be summarized, and a shared parameter file that can be called at any time in the Revit software can be formed, which facilitates the quick calling of various parameters of the horse head doors during subsequent modeling.

[0025] In one embodiment, the statistical basic information is checked for omissions and deficiencies, and the same parameter information in different horse head gates is processed to the same standard. This ensures that in the subsequent modeling process, the required parameter information of each model can be quickly and accurately called without missing or mismatching phenomena, ensuring the high efficiency of the entire modeling process.

[0026] Step S3. In Revit software, locate the spatial position of any type of horse head door model, establish a reference plane, use dimensioning and alignment functions to associate the physical outline of the current type of horse head door with the reference plane, and use the shared parameter file to quickly establish and control the parameters of each current type of horse head door in the target project to form models of all horse head doors under the current type of horse head door.

[0027] In this step, a basic horse head gate model is first established based on the basic information of the horse head gate. The various parameters in it are associated with the reference plane. When other horse head gate models of this type are established subsequently, they can be directly modified on this basis to complete the rapid establishment and control of the parameters of the new horse head gate.

[0028] In one embodiment, when locating the spatial position of any type of horse head door model, the following steps are included:

[0029] Step S311: Select a construction facility in the target project as a positioning base point based on the basic information, such as a main well or a secondary well in the target project.

[0030] Step S312: Use the model lines of the Revit software to establish the center of the 2000mm×2000mm rectangle to complete the spatial positioning of the horse head door model.

[0031] This step can provide accurate positioning and reference information for subsequent modeling operations.

[0032] In one embodiment, in step S3, when establishing the reference plane, the positioning and drawing of the median line of the horse head gate model are completed based on the spatial position positioning of the horse head gate model.

[0033] Before using the dimensioning and alignment functions to associate the solid outline of the current type of horse head door with the reference plane, perform the following steps:

[0034] Step S321: Based on the basic information of the current type of horse head door, open the metric regular model of the new family creation function of Revit.

[0035] Step S322: On a horizontal plane perpendicular to the center line of the horse head gate, use a reference plane to establish three horizontal lines and four vertical lines, and the horizontal lines and vertical lines intersect to form a control network.

[0036] Step S323: Based on the basic information, use the creation function to build models for the constant-section laneway, variable-section laneway, and the intersection position between the laneway and the shaft of the current type of horse head gate.

[0037] Among them, for constant cross-section tunnels, entity lofting is used to directly complete the establishment;

[0038] The establishment of the variable-section roadway model includes: establishing two sets of control networks to simultaneously control the solid model and the hollow model; using the creation function, first establishing the solid model, and then establishing the corresponding hollow model to complete the cutting of the solid model, thereby completing the establishment of the variable-section roadway model;

[0039] The model establishment for the intersection of the tunnel and the shaft includes: completing the complete modeling of the main tunnel model, and then using the hollow model to penetrate the preset intersection area to form a positioning opening; establishing the main structure of the shaft through solid stretching modeling technology; using hollow Boolean operations to cut the redundant shaft extension parts in the tunnel model, thereby completing the modeling of the intersection.

[0040] In this embodiment, when establishing the solid model and the hollow model, the order should be followed: the solid model should be established first and the hollow model should be established later.

[0041] Through the operations in step S3, model files of various horse head gates of the same type in the target project can be quickly established.

[0042] Step S4: Repeat step S3 until the modeling task of each horse head door under all types of horse head doors in the target project is completed.

[0043] At this point, all the horse-head door models in the target project have been established. In one embodiment, the Revit-based parametric modeling method for horse-head doors further includes step S5: creating a model storage folder based on the basic information to store all the horse-head door model files, where the folder is named "horse-head door model library" and the horse-head door model file name includes the type, material, and support material of the current horse-head door. This facilitates user use by quickly locating the relevant horse-head door model.

[0044] The following is a further explanation of the above-mentioned parametric modeling method of the horse head door based on Revit, with reference to a specific embodiment. In this embodiment, the relevant data is presented using a double-sided flat-top horse head door as an example. Accordingly, the method includes the following steps:

[0045] First, from the design plan of the target project, the basic information of all the horse head gates is collected, including the type of horse head gate, the size of the horse head gate, the positioning information of the horse head gate and the support materials.

[0046] This information is then categorized and recorded in an Excel spreadsheet for easy access in Revit. The names of the basic information recorded in Excel are consistent with the parameterized names, and a shared parameter file is created within the Revit tab based on these names. This process also includes checking for omissions in the statistical information and correcting any missing parameters in different gates.

[0047] Taking the double-sided flat-top horse head gate as an example, its specific basic information is shown in Table 1 below. The supporting materials are concrete and anchor rods.

[0048] Table 1:

[0049]

[0050]

[0051] Then, in Revit software, based on the above basic information, the main well in the project is selected as the positioning base point, and the center of the 2000mm×2000mm rectangle established by the model line of Revit software is used to complete the spatial position positioning of the horse head door model, and a reference plane is established. The metric conventional model of the new family function of Revit is opened, and 3 horizontal lines and 4 vertical lines are established on the horizontal plane perpendicular to the center line of the horse head door using the reference plane. The horizontal and vertical lines intersect to form Figure 2 The control network shown in the figure is then used to build models of the constant-section laneway, variable-section laneway, and laneway-to-shaft intersection of the current type of horse-head door based on the basic information. The dimensioning and alignment functions are used to associate the outline of the horse-head door entity with the reference plane. Thus, a benchmark double-sided flat-top horse-head door model is completed. Figure 3 As shown, each basic information therein is associated with the reference plane. Subsequently, the relevant parameter information in the shared parameter file can be directly called in the software to modify and control it to form a horse head gate model of another specification size.

[0052] Finally, use the above shared parameter file to quickly establish and control the parameters of other horse head doors in the target project, forming the model of all double-sided flat-top horse head doors in the target project. Figure 4 As shown, for horse head gate models of other specifications and sizes, a new model can be formed by simply adjusting the specific values ​​of each parameter in the software, which significantly reduces the workload during modeling.

[0053] Through the above-mentioned Revit-based parametric modeling method for horse-head doors, when modeling the horse-head door model of the target project, only a complete baseline model needs to be established for each type of horse-head door. Models of other specifications and sizes of the same type only need to adjust and control various parameters on this basis to form a new horse-head door model, which greatly reduces the modeling workload and improves modeling efficiency.

[0054] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
