Description

Technical Field

[0001] This invention relates to the field of innovative applications of parametric design, and in particular to a BIM model analysis method for deriving basement zoning construction schemes. Background Technology

[0002] Grasshopper (GH) is a visual programming language that runs on the Rhino platform. It's a mainstream software for data-driven design and also overlaps with interaction design. Compared to traditional design methods, GH's two biggest advantages are: first, it allows users to input commands, enabling the computer to automatically generate results based on predetermined algorithms, with the results not limited to models, video streams, or visualizations; second, by writing algorithm programs, repetitive mechanical operations and numerous logical evolutionary processes can be replaced by the computer's iterative calculations, and adjustments can be made directly by modifying parameters. These methods effectively improve the efficiency of designers.

[0003] In current construction projects, Revit software is typically used for 3D design. Designers often need to first complete 2D drawings using CAD and then create 3D models based on those drawings using Revit. However, basements have complex terrain and elevations, numerous components, and varying underground elevations for each component. These parameters must be entered into each component individually by the designer, resulting in a huge workload for modeling, which is time-consuming and labor-intensive, severely restricting the application of BIM technology in basement construction design. Summary of the Invention

[0004] To address the problems existing in the current technology, a BIM model analysis method for deriving zoning construction schemes for basements is provided. This method is mainly used to visualize the derivation of zoning construction schemes and assist in decision-making regarding zoning construction schemes.

[0005] To address the aforementioned technical problems, a first aspect of this application provides a BIM model analysis method for simulating basement zoning construction schemes, comprising the following steps:

[0006] Step 1: Create a complete BIM model in Revit that requires zoned construction;

[0007] Step 2: Create closed curves in Rhino to divide each partition and their corresponding partition names;

[0008] Step 3: Use the Rhino Inside for Revit plugin to split and rebuild the BIM model in Revit, and add partitioning parameters to each split Revit instance;

[0009] Step 4: Add a filter to the Revit view template and assign different display colors according to the values ​​of the partition parameters;

[0010] Step 5: Using Revit's native schedule, calculate the concrete volume within each partition based on the instance's partition parameter values.

[0011] Step 6: By adjusting the division of the zoning curves in Rhino, real-time values ​​of each concrete component are obtained to make decisions on the zoning construction plan.

[0012] Furthermore, the BIM model established in step one and the closed curve established in step two share the same origin.

[0013] Furthermore, the BIM model in step one includes beams, floor slabs, columns, and walls.

[0014] Furthermore, step three includes:

[0015] Use the Rhino Inside for Revit plugin to read Revit's native floor slab information and filter the floor slab's outer contour line and internal opening line by area;

[0016] Read the partition curves in Rhino to cut the outer contour lines of the selected floor slabs, forming the outer contour lines of the sub-slabs;

[0017] Use the outer contour of the sub-slab to inherit the original floor slab information of the parent slab and regenerate a new floor slab in Revit;

[0018] The internal opening lines are read to generate the shaft opening;

[0019] By determining whether the partition name text is within the outline of the partition curve, the partition curve is matched one-to-one with the partition name;

[0020] Analyze whether the geometric center point of the new floor slab is within the zoning curve outline, determine the zoning of the new floor slab, and add zoning parameter values ​​for each new floor slab.

[0021] Furthermore, the original floor slab information includes the floor slab outline, slab thickness, and elevation.

[0022] Furthermore, the steps for filtering out the outer contour line and internal opening line of the floor slab by area include: defining the curve with the largest enclosed area as the contour line and the rest as internal opening lines.

[0023] A second aspect of this application provides a computer device, the computer device comprising:

[0024] Memory, used to store executable instructions;

[0025] When executing executable instructions stored in the memory, the processor implements the steps of the BIM model analysis method for basement zoning construction scheme derivation as described in any of the preceding claims.

[0026] A third aspect of this application provides a computer-readable storage medium storing executable instructions, which, when executed by a processor, implement the steps of the BIM model analysis method for basement zoning construction scheme derivation as described in any of the preceding claims.

[0027] A fourth aspect of this application provides a computer program product, including a computer program or instructions, which, when executed by a processor, implement the steps of the BIM model analysis method for basement zoning construction scheme derivation as described in any of the preceding claims.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. Enable batch partitioning and reconstruction of Revit models and assignment of partition parameter values;

[0030] 2. Due to its advantages of visualization, real-time adjustment, and real-time data updates, it facilitates decision-making for zoning construction plans. Attached Figure Description

[0034] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0035] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] First, the following are explanations of some of the terms that appear in the text:

[0037] Revit is a software used to create Building Information Models (BIM), and it is currently the mainstream software for building BIM models.

[0038] Grasshopper (GH for short) is a visual programming language that runs on the Rhino platform and is one of the mainstream software for data-driven design.

[0039] Rhino Inside for Revit is a plugin that integrates with the Revit platform, allowing the Rhino platform to be embedded within the Revit interface and enabling data interaction between the two software programs via the Grasshopper battery pack.

[0040] See Figure 1 As shown in the figure, this invention provides a BIM model analysis method for basement zoning construction scheme derivation, mainly used to visualize the derivation of zoning construction schemes and assist in zoning construction scheme decision-making. The method mainly includes the following steps:

[0041] Step 1: Create a complete BIM model (beams, slabs, columns, walls) in Revit that requires zoned construction;

[0042] Step 2: In Rhino, create closed curves that divide the space into partitions (with the same origin as the 3D model in Step 1) and their corresponding partition names (1-1, 1-2, 2-1, 2-2, etc.). See [link / reference]. Figure 2 As shown;

[0043] Step 3: Use Rhino Inside for Revit to split and rebuild the BIM model (beams, slabs, columns, walls, etc.) in Revit, and add partitioning parameters to each split Revit instance;

[0044] Step 4: Add a filter to the Revit view template and assign different display colors according to the values ​​of the partition parameters;

[0045] Step 5: Using Revit's native schedule, calculate the concrete volume within each partition based on the instance's partition parameter values.

[0046] Step 6: By adjusting the division of the zoning curves in Rhino, real-time values ​​of each concrete component are obtained to make decisions on the zoning construction plan.

[0047] In step 3, Rhino Inside for Revit utilizes Grasshopper battery pack technology. Taking floor slab partitioning as an example, the programming logic of the Grasshopper battery pack is as follows:

[0048] 1. Use the Rhino Inside for Revit plugin to read Revit's native floor slab information (floor slab outline, slab thickness, elevation);

[0049] 1.1. Filter out the outer contour line and internal opening line of the floor slab by area (the largest area enclosed by the curve is the contour line, and the rest are internal opening lines);

[0050] 2. Read the partition lines in Rhino and cut the outer contour lines in 1.1 to form the outer contour lines of the sub-plates;

[0051] 3. Use the outer contour lines of the sub-slabs in step 2 to inherit the original floor slab information from the parent slab in step 1, and regenerate new floor slabs in Revit.

[0052] 4. Read the internal opening lines from 1.1 to generate the shaft opening.

[0053] 5. By determining whether the partition name text is within the partition line outline, the partition lines are matched one-to-one with the partition names;

[0054] 6. Analyze whether the geometric center point of the new floor slab in step 3 is within the zoning line outline, determine the zoning of the new floor slab, and add zoning parameter values ​​for each new floor slab.

[0055] This invention provides a BIM model analysis method for basement zoning construction scheme derivation. Through the above technical solution, it realizes batch division and reconstruction of Revit models and assignment of zoning parameter values; and due to Grasshopper's advantages of visualization, real-time adjustment, and real-time data updates, it provides convenience for decision-making on zoning construction schemes.

[0056] This invention also provides a computer program product or computer program, which includes computer instructions stored in a computer-readable storage medium. A processor of a computer device reads the computer instructions from the computer-readable storage medium and executes the computer instructions, causing the computer device to perform the steps of the BIM model analysis method for basement zoning construction scheme derivation described in the embodiments of this application.

[0057] This invention provides a computer-readable storage medium storing executable instructions. When the executable instructions are executed by a processor, the processor will execute the steps of the BIM model analysis method for basement zoning construction scheme derivation provided in this invention.

[0058] In some embodiments, the computer-readable storage medium may be a memory such as FRAM, ROM, PROM, EPROM, EEPROM, flash memory, magnetic surface memory, optical disk, or CD-ROM; or it may be a variety of devices including one or any combination of the above-mentioned memories.

[0059] In some embodiments, executable instructions may take the form of a program, software, software module, script, or code, written in any form of programming language (including compiled or interpreted languages, or declarative or procedural languages), and may be deployed in any form, including as a standalone program or as a module, component, subroutine, or other unit suitable for use in a computing environment.

[0060] As an example, executable instructions may, but do not necessarily, correspond to files in the file system. They may be stored as part of a file that holds other programs or data, for example, in one or more scripts in a HyperText Markup Language (HTML) document, in a single file dedicated to the program in question, or in multiple collaborating files (e.g., a file that stores one or more modules, subroutines, or code sections).

[0061] As an example, executable instructions can be deployed to execute on a single computing device, or on multiple computing devices located in one location, or on multiple computing devices distributed across multiple locations and interconnected via a communication network.
