Description

Technical Field

[0001] The present invention relates to a template drawing system and method, and in particular to a template drawing system and method based on an Autodesk modeling product. Background Art

[0002] Wooden formwork has a smooth surface, can be sawed and drilled, and is resistant to low temperatures, making it suitable for winter construction. The surface of the cast object is smooth and beautiful, does not contaminate the concrete surface, is easy to assemble and disassemble, is simple to operate, and can be made into curved flat formwork. Wooden formwork is still widely used in the market, especially for complex structures and nodes. Currently, in buildings with cast-in-place reinforced concrete structures, formwork engineering generally accounts for about 20% of the structural engineering cost. In particular, the loss of wooden formwork used for complex structures can be as high as 20%-30%. During wooden formwork construction, pattern making, cutting, and mold matching are directly related to the loss value, which in turn affects the refined management and efficiency of the project. Currently, wooden formwork still has problems such as low pattern making efficiency, difficulty in pattern making for complex nodes, lack of intuitiveness, high on-site cutting loss rate, and low precision.

[0003] Existing formwork drawing methods calculate the dimensions of each concrete formwork piece, generate a formwork diagram, and generate a code for cutting. A dedicated parameter module then generates the formwork contact area, primarily for project quantity accounting and settlement. Existing formwork drawing methods fail to reflect formwork matching results or individual formwork pieces within the entire fixed-length formwork for optimal layout. This method does nothing to address the high loss rate of wooden formwork, failing to reduce construction costs or improve efficiency.

[0004] At the same time, existing template drawing methods are all systematically developed and heavily quantified, often requiring comprehensive application of various calculations, specifications, wood backing strips, and tie bolts. This makes it impossible to achieve optimal template layout and drawing on a fixed-length template. Furthermore, the software is expensive and suffers from poor applicability and compatibility. Therefore, a template drawing system and method based on Autodesk modeling products is needed to address the existing inability to reflect template matching results or individual templates on the entire fixed-length template for optimal layout and drawing. Summary of the Invention

[0005] The purpose of the present invention is to provide a template drawing system and method based on Autodesk modeling products, which can solve the problem in the prior art that the mold matching results or a single template cannot be reflected in the entire fixed-length template for optimal layout and drawing.

[0006] The present invention is achieved in that:

[0007] A template drawing system based on Autodesk modeling products, comprising:

[0008] The component template extracts the coplanar parameter module, which is used to identify and delete the intersecting vertical coplanarities between various structural components in the Autodesk modeling product environment;

[0009] Component template decomposition and stacking parameter module, used to decompose and stack various 3D component templates into 2D planes in the Autodesk modeling product environment;

[0010] The component template optimization tiling parameter module is used to convert component templates stacked on a two-dimensional plane into a single fixed-length template in the optimal arrangement and combination within the Autodesk modeling product environment;

[0011] The component template coding drawing parameter module is used to obtain the optimized plane cutting drawing of the two-dimensional fixed-length template in the Autodesk modeling product environment, and to encode the component template one by one.

[0012] A template drawing method using a template drawing system based on an Autodesk modeling product comprises the following steps:

[0013] Step 1: Use various software of Autodesk modeling products to create the original BIM civil engineering model or establish a new BIM civil engineering model;

[0014] Step 2: Delete the intersecting vertical coplanarities between beams, slabs, columns, walls and other components in the BIM civil engineering model to obtain a three-dimensional non-coplanar template model;

[0015] Step 3: Disassemble the three-dimensional non-coplanar template model into equal proportions and stack them on a two-dimensional plane;

[0016] Step 4: Arrange and combine the component templates stacked on the two-dimensional plane onto a single fixed-length template to obtain the optimal plane layout;

[0017] Step 5: After obtaining the optimal plane arrangement, the component template encoding drawing parameter module encodes the component template, and the component templates in the two-dimensional plane and the three-dimensional model correspond to each other.

[0018] Described step 2 comprises the following sub-steps:

[0019] Step 2.1: In the BIM civil engineering model, use the component template to extract the coplanar parameter module to identify the coplanarity between components such as beams, slabs, columns, and walls, and analyze whether the coplanarity between components is coplanar or embedded;

[0020] Step 2.2: The component template extracts the coplanar parameter module, divides the structural components into similar items according to the coplanar type or embedded coplanarity, forms a grid model, and uses the grid model in the geometric space to perform two types of Boolean code operations or Boolean operation inversion retention;

[0021] Step 2.3: The component template extracts the coplanar parameter module to trim and delete the coplanar surfaces between the components, and removes the overlapping surfaces between the beam and the floor slab, and the floor slab and the column, to obtain an accurate three-dimensional non-coplanar template model of the contact surface with the concrete.

[0022] Described step 3 comprises the following sub-steps:

[0023] Step 3.1: The component template decomposition and stacking parameter module uses the most basic computer triangular mesh model, uses arrays and strings to subdivide the triangular mesh surface, uses the quadrify string to restore it to a standard quadrilateral surface, and uses the vertical normal algorithm to obtain the three-dimensional spatial angle of the quadrified orthogonal surface;

[0024] Step 3.2: The component template decomposition and stacking parameter module uses computer-based triangular mesh surfaces. The template surfaces in all directions in three dimensions are quadrilateralized and exploded in sequence, and then tiled and stacked in equal proportions on the same two-dimensional plane.

[0025] Step 3.3: The normal direction of the axillary beam is calculated using anisotropic data, and unfolded according to the normal surface angle to obtain a template processing style consistent with the actual cutting size.

[0026] Described step 4 comprises the following sub-steps:

[0027] Step 4.1: Set the plane parameters of the actual fixed-length template. The component template optimization tiling parameter module converts the component templates that are tiled and stacked in equal proportions onto the fixed-length template plane through the computer plane graphics engine and JavaScript.

[0028] Step 4.2: Use the component template to optimize the tiling parameter module to write the permutation and combination tool string to automatically arrange the component template on the fixed-length template plane.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. The present invention relies on the BIM three-dimensional model established by Autodesk modeling products. After the component templates of the three-dimensional model are de-coplanarized through the component template extraction coplanar parameter module, the component template decomposition and stacking parameter module and the component template optimization tiling parameter module are used to convert the component templates in proportion and intelligently tile and sort them onto the two-dimensional fixed-size template, so as to maximize the use of the templates and realize the automation, accuracy, systematization and intelligence of the template drawing. The component template coding drawing parameter module is used to number the component templates of the two-dimensional plane and the three-dimensional model accordingly, which is used to guide the on-site cutting and installation of the template, which is conducive to precise construction, reduces waste and improves construction efficiency.

[0031] 2. Since the present invention uses Autodesk modeling products to establish BIM three-dimensional models, it is applicable to various software of Autodesk modeling products, has good compatibility, low development cost, and can accurately and efficiently produce template processing drawings for BIM models in any format. The software calculates areas and dimensions accurately, reducing manual calculation time and improving processing efficiency, especially for complex nodes of building structures. It can automatically cut out a fixed-size template to the maximum extent possible, reducing rework caused by manual re-patterning or errors in complex mixed node areas, and saving costs.

[0032] 3. The present invention can split all complex structural components into single-piece fixed-length template processing drawings with one click, saving the waste of scraps caused by unreasonable cutting by on-site workers, optimizing labor losses, reducing template loss rate, greatly saving project costs, and eliminating erroneous processing. It is conducive to improving on-site construction efficiency and construction quality, reducing costs and increasing efficiency, and providing effective support for energy saving, emission reduction, low carbon, green, and smart construction.

DETAILED DESCRIPTION

[0036] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] Please see the attached Figure 1 , a template drawing system 10 based on Autodesk modeling products, comprising:

[0038] The component template extracts the coplanar parameter module 20, which is used to identify and delete the intersecting vertical coplanarities between various structural components in the Autodesk modeling product environment.

[0042] Compared with traditional template software, the present invention realizes the intelligent arrangement of wood template cutting and waste through the functional loading of component template coplanar parameter module 20, component template decomposition and stacking parameter module 30, component template optimization tiling parameter module 40 and component template coding and drawing parameter module 50. It has the advantages of fast calculation, accurate cutting, convenient cutting, fast speed, obvious lightweight effect, simple operation, strong applicability, etc., which can maximize the elimination of problems such as template cutting waste.

[0043] Please see the attached Figure 1 and attached Figure 2 A template drawing method based on Autodesk modeling products includes the following steps:

[0044] Step 1: Use various software of Autodesk modeling products to create an original BIM (Building Information Modeling) civil engineering model or establish a new BIM civil engineering model.

[0045] The Autodesk modeling product series software includes AutoCAD, Revit, 3ds Max, Civil 3D, Ecotect, Navisworks, Inventor, Remake, etc. Autodesk modeling products are commonly used design software in the construction field. Their functions and usage methods will not be repeated here.

[0046] Step 2: Delete the intersecting vertical coplanarities between beams, slabs, columns, walls and other components in the BIM civil engineering model to obtain a three-dimensional non-coplanar template model.

[0047] Described step 2 comprises the following sub-steps:

[0048] Step 2.1: In the BIM civil engineering model, use the component template to extract the coplanar parameter module 20 to identify the coplanarity between components such as beams, plates, columns, and walls, and analyze whether the coplanarity between the components is coplanar or embedded.

[0049] Step 2.2: The component template extracts the coplanar parameter module 20, which divides the structural components into similar items according to the coplanar type or embedded coplanarity to form a grid model, and uses the grid model of the geometric space to perform two types of Boolean code operations or Boolean operation inversion retention.

[0050] Boolean operations are logical deduction methods based on digital symbols, including union, intersection, and subtraction. These operations are used in graphics processing to combine simple basic shapes to create new forms. Boolean operations have evolved from two-dimensional to three-dimensional Boolean operations. Two types of Boolean code operations, or Boolean inversion and preservation, are commonly used in geometric modeling operations and will not be discussed here.

[0051] Step 2.3: The component template extracts the coplanar parameter module 20 to trim and delete the coplanar surfaces between the components, and processes the overlapping surfaces between the components such as the coplanarity between the beam and the floor slab, the coplanarity between the floor slab and the column, so as to obtain an accurate three-dimensional non-coplanar template model of the contact surface with the concrete.

[0052] Since the three-dimensional BIM civil engineering model is created based on Autodesk modeling products, the component template coplanar parameter module 20 can use Revit structural model, Glodon structural model, PKPM Yingjianke structural model and any other structural model established by BIM software as the basic model according to the structural characteristics and complex forms, and quickly, automatically and accurately remove the coplanarity of the three-dimensional components.

[0053] Step 3: Disassemble the three-dimensional non-coplanar template model in equal proportions and stack it on a two-dimensional plane.

[0054] Described step 3 comprises the following sub-steps:

[0055] Step 3.1: The component template decomposition and stacking parameter module 30 uses the most basic computer triangular mesh model, uses arrays and strings to subdivide the triangular mesh surface, and uses the quadrify string to restore it to a standard quadrilateral surface, meeting the basic algorithm and modeling theory of the template quadrilateral surface. Through the vertical normal algorithm, the three-dimensional spatial angle of the quadrified orthogonal surface is obtained.

[0056] Step 3.2: The component template decomposition and stacking parameter module 30 uses a computer-based triangular mesh surface to quadrify the template surfaces in all directions in three dimensions and then explode them, and then lay them flat and stacked in equal proportions on the same two-dimensional plane.

[0057] The tiled template faces overlap, preventing any issues like missing, omissions, or errors. The plane faces correspond to the same number of template faces as the actual component's 3D model, with no changes to size or area. The scripting language within the component template decomposition and stacking parameter module (30) ensures a one-to-one mapping of the 3D and 2D plane face counts.

[0058] Step 3.3: The normal direction of the axillary beam is calculated using anisotropic data, and unfolded according to the normal surface angle to obtain a template processing style consistent with the actual cutting size.

[0059] Step 4: Arrange and combine the component templates stacked on the two-dimensional plane onto a single fixed-length template to obtain the optimal plane layout.

[0060] Described step 4 comprises the following sub-steps:

[0061] Step 4.1: Set the plane parameters of the actual fixed-size template, for example, 1.2m×2.4m. The component template optimization tiling parameter module 40 converts the component templates that are tiled and stacked in equal proportions to the 1.2m×2.4m fixed-size template plane through a computer plane graphics working engine and JavaScript.

[0062] Step 4.2: Use the permutation and combination tool string writing in the component template optimization tiling parameter module 40 to automatically arrange the component template on the fixed-length template plane.

[0063] Preferably, the polygonal face number edges, corner alignment method, and script language requirements of several arrangement and combination methods are adopted, and the principle of setting concentration and leaving no gaps between templates is adopted. The component template is automatically arranged to the lower left corner of the fixed-size template plane, and the space in the upper right corner is maximized to reduce the waste of the template and obtain the optimal layout of the plane, thereby realizing automation, optimization, minimum waste of area, and the most reasonable template module for intelligent cutting.

[0064] Convert the three-dimensional model into a two-dimensional plane, and optimize the combination of each component template on a single fixed-length template to maximize the utilization rate of the fixed-length template and reduce the loss rate.

[0065] Step 5: After obtaining the optimal plane arrangement, the component template encoding drawing parameter module 50 encodes the component template, and the component templates in the two-dimensional plane and the three-dimensional model correspond to each other.

[0066] This invention not only accurately calculates the size and area of a single component template, but also optimally combines the component templates into a two-dimensional single-sheet fixed-size template based on the parameters of a single 1.2m×2.4m fixed-size template (2.88 square meters). This allows for rapid generation of a cutting template processing diagram and assigns corresponding numbers to the component templates in the two-dimensional plane and the three-dimensional model, facilitating on-site construction and assembly. During construction, on-site workers can compare the three-dimensional model with the two-dimensional plane, facilitating efficient and convenient assembly of complex templates into corresponding positions, providing visual guidance. This can particularly improve the quality and efficiency of template assembly construction at complex nodes.

[0067] This invention can automatically arrange small, beveled formwork pieces, such as column heads and axillar beams, or formwork with complex joints, minimizing the use of single, fixed-length wooden formwork sheets. By converting 3D models into 2D planes, this approach maximizes savings in wooden formwork consumables, minimizing cutting lengths, and eliminating any scrap. This maximizes formwork cutting efficiency, saving up to 32% in wooden formwork for large-scale project cutting. This also enables visualization of both 3D models and 2D cutting diagrams.

[0068] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
