[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.

[0021] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0022] Example 1

[0023] Existing technologies typically employ a reverse design approach for quantity take-off in building model calculations. The accuracy of the calculation results is dependent on the accuracy of the CAD model conversion, and the efficiency of the calculation is also limited by the efficiency of the CAD model conversion. Specific drawbacks are as follows:

[0024] 1. Low quantity calculation efficiency: This mode introduces a form conversion process, and the efficiency of quantity calculation is limited by the efficiency of CAD form conversion. In a normal residential building project, it takes about 200 to 500 minutes to import CAD into GTJ to complete form conversion and verification. If the design drawings are hand-drawn, this time will increase significantly.

[0025] 2. Quantity calculation accuracy: CAD model making inevitably introduces the issue of information conversion accuracy, which will directly affect the correctness of the quantity calculation results.

[0026] 3. Design Rework: Since the design output is two-dimensional drawings, the design work is completed before the 3D model is created. After the 3D model is created, BIM technology can be used for model visualization and design validity checks. If problems are found in the model at this stage, modifications need to be made on the 3D model, and the design needs to be redesigned and updated in the CAD drawings.

[0027] 4. Low audit efficiency: Because the design model and engineering quantity are independent, the engineering quantity analysis is not intuitive during the audit, and the efficiency of troubleshooting is low.

[0028] This embodiment provides a method for outputting quantities from an integrated design and quantity calculation model. This method is implemented using GTJ quantity calculation software. Specifically, when calculating the quantities of building engineering projects, GTJ software can integrate civil engineering and reinforcement models, completing modeling in one step. Each component contains both reinforcement and civil engineering information. This reduces problems and editing during the data import process, improving work efficiency. In particular, the response time for functional operations on projects of the same scale is more than 30% faster than the original single reinforcement / civil engineering model, while the efficiency of project aggregation is more than 5 times faster. Furthermore, when importing CAD drawings into GTJ quantity calculation software, there is no need to convert them to T3 format. Unrecognized components can be accurately located and alerted, achieving more accurate automatic identification and easy modification. The identification operation is streamlined: extraction-identification-verification. Verification and checking functions are provided at each stage of the process to ensure the accuracy of each part of the model.

[0029] Figure 1 The flowchart of the output method of the integrated design quantity calculation model is shown, as follows: Figure 1 As shown, the output method of this integrated design quantity calculation model may include steps S1 to S4, wherein:

[0030] Step S1: Obtain the 3D design model and the 2D CAD drawing, wherein the 3D design model and the 2D CAD drawing are uniquely corresponding;

[0031] A 3D design model is a three-dimensional model created using design software. This model can include data such as the project name, area, floors, components, and geometric elements. The design software can be BIM model design software or various types of design software applicable to conventional technical fields; no restrictions are placed here. Two-dimensional CAD drawings are the two-dimensional representation of the 3D design model, used for detailed descriptions of local details of the project. In the actual quantity calculation process, the 3D design model and the 2D CAD drawings are uniquely corresponding and together serve as the basic data for the quantity calculation process.

[0032] Step S2: Generate a three-dimensional initial quantity calculation model based on the three-dimensional design model;

[0033] Conventional quantity surveying methods typically involve creating a 3D model from 2D CAD drawings to obtain basic data, which is then visualized and validated to arrive at the final quantity survey result. However, there are fundamental differences in the representation of 2D drawings and 3D models. The conversion process requires numerous information conversion algorithms, and architectural model data is often vast and complex in practical applications, inevitably leading to accuracy issues that directly affect the correctness of the quantity survey results.

[0034] This embodiment uses the three-dimensional design model as one of the basic data for determining the quantity of building works, which reduces the problem of data dimension mismatch, enables faster conversion of relevant model data, and improves the overall efficiency of quantity calculation.

[0035] Optionally, step S2 may include steps S21 to S23, wherein:

[0036] Step S21: Read the business level information of the 3D design model based on the 3D design software;

[0037] The 3D design software can be conventional design software such as CAD and SolidWorks, or other similar 3D design software available on the market; there are no restrictions. Business-level information can include wall components, shape information, elevation, column cross-sections, structural categories, or slopes. By identifying different categories of information in the 3D design model, a 3D quantity calculation model can be created.

[0038] Step S22: Generate quantity calculation information for the 3D design model based on the category to which the business level information belongs;

[0039] Each business level information has a corresponding category. In this embodiment, the category of business level information can be elevation, family type, or primitive attribute. Each category of business level information has a corresponding information conversion algorithm. By matching the category of business level information with the information conversion algorithm, the computational quantity information corresponding to each category of business level information can be obtained.

[0040] Optionally, step S22 may include steps A1 to A3, wherein:

[0041] Step A1: Convert the business level information belonging to the elevation category into the floor quantity calculation information of the 3D design model;

[0042] Floor quantity calculation information can be obtained by statistically analyzing the relative distance between any two adjacent elevation categories.

[0043] Step A2: Convert the business hierarchy information belonging to the family type into component quantity calculation information of the 3D design model;

[0044] The system reads family types (component types such as walls, beams, slabs, or columns) from the 3D design model and, in conjunction with the user's real-time settings, maps these family types into text information according to a preset specification sequence. This text information serves as the component quantity calculation information for the 3D design model. The preset specification sequence is a sequential combination of family type information and user-defined settings.

[0045] Step A3: Convert the business-level information belonging to the category of graphic element attributes into temporary graphic element quantity calculation information of the 3D design model.

[0046] The system sequentially reads the corresponding graphic elements according to region, floor, and component type, and iterates through all found graphic elements. It then converts the attributes and volume information of each graphic element to generate temporary graphic element quantity calculation information. This temporary information can be a text sequence combining graphic element attributes and volume information. Graphic element attributes can be any conventional attribute such as length or cross-sectional area, while volume information can be the graphic element's location within the entire 3D design software.

[0047] Step S23: Based on the 3D quantity calculation software, reverse the quantity calculation information to generate a 3D initial quantity calculation model.

[0048] Among them, reverse construction can be used to create a three-dimensional model of engineering information obtained from two-dimensional CAD drawings / three-dimensional design software, and construct the corresponding three-dimensional structural model.

[0049] The 3D quantity take-off software can be GTJ 3D quantity take-off software or other similar 3D design software on the market; no restrictions are placed here. The various quantity take-off information obtained above is then reverse-engineered within the 3D quantity take-off software, that is, the text data is restored to a 3D model, ultimately obtaining an initial 3D quantity take-off model. This initial 3D quantity take-off model only contains architectural structural appearance data such as project, area, floor, component, and element, excluding embedded structural data such as steel reinforcement. Since the 3D design model reflects the overall appearance of the project, the component type appearance data it includes can completely reflect the actual project. Therefore, extracting appearance type data from the 3D design model ensures the accuracy of the model data, thereby further improving the accuracy of the quantity take-off results.

[0050] Optionally, step S23 may include steps B1 to B3, wherein:

[0051] Step B1: Obtain a preset data protocol, wherein the preset data protocol includes a category identifier and a data conversion rule, and the category identifier and the data conversion rule are uniquely corresponding;

[0052] The default data protocol can be the GFC (Glodon Foundation Classes) data protocol, also known as the BIM data interface. This protocol defines the standards for describing the model data and relationships of projects, areas, floors, components, and elements, providing a unified technical standard for communication and conversion between different file formats, facilitating the transfer and reading of design documents across different platforms. The default data protocol includes type identifiers for projects, areas, floors, components, elements, and relationships, along with the corresponding data conversion rules for each type.

[0053] Step B2: Convert the quantity calculation information according to the category identifier and data conversion rules to generate a three-dimensional initial quantity calculation model.

[0054] According to the model data and relationship format of the project, area, floor, component, and graphic element agreed in the GFC protocol, the text quantity calculation information data of the 3D design model is converted into a 3D GTJ project.

[0055] Specifically, the process involves loading text quantity calculation information. First, the project category identifier is read and matched with the category of the data in the quantity calculation information. The matched text quantity calculation information is then converted using project conversion rules to complete the reverse reconstruction of project category data. Second, the region category identifier is read, and the corresponding region quantity calculation information is obtained by traversing the quantity calculation information. The region quantity calculation information is then converted using region conversion rules to complete the reverse reconstruction of region category data. Third, the floor information identifier is read, and the corresponding floor quantity calculation information is obtained by traversing the quantity calculation information. The floor quantity calculation information is then converted using floor conversion rules to complete the reverse reconstruction of floor category data. Fourth, the element attribute and volume information category identifiers are read again, and the corresponding temporary element quantity calculation information is obtained by traversing the quantity calculation information. The temporary element information is then converted using element attribute and volume information conversion rules to complete the reverse reconstruction of temporary element category information. Finally, the connection relationship of the element information is converted using association relationship conversion rules to finally obtain the initial 3D quantity calculation model.

[0056] Step S3: Determine the reinforcement quantity information based on the two-dimensional CAD drawings and the three-dimensional initial quantity calculation model;

[0057] Two-dimensional CAD drawings are typically used to reflect specific details in architectural engineering. Therefore, it is more accurate to determine embedded data such as reinforcement information from two-dimensional CAD drawings. At the same time, the data extraction is more focused, which also improves the recognition efficiency.

[0058] By identifying structural reinforcement information marked on the plane in 2D CAD drawings and matching it with the corresponding 3D initial quantity calculation model, the accuracy of reinforcement information identification has been improved.

[0059] In this embodiment, steps S23 and S3 are both executed in the GTJ quantity calculation software, which facilitates direct quantity calculation after the three-dimensional quantity calculation model is generated, thus speeding up the quantity calculation efficiency.

[0060] Optionally, step S3 may include steps S31 to S34, wherein:

[0061] Step S31: Read the floor table information summarized from the two-dimensional CAD drawings and create three-dimensional floor information;

[0062] Step S32: Divide the 2D CAD drawing into multiple partial drawings;

[0063] The 2D CAD drawing is divided according to the minimum unit rule to obtain multiple partial drawings. The minimum unit rule can be the component information of a certain category in a certain floor.

[0064] Step S33: Match the local drawings with the three-dimensional floor information and the three-dimensional initial quantity calculation model to achieve the positioning of the local drawings;

[0065] First, the local drawing is positioned for the first time (i.e., local positioning) based on the matching results between the 3D floor information and the floor to which the component information in the local drawing belongs. Then, the local drawing is positioned for the second time (i.e., global positioning) based on the component information in the 3D initial quantity calculation model.

[0066] Step S34: Extract layers and identify information from the located local drawings according to the component type to determine the reinforcement quantity information.

[0067] The process involves traversing the segmented and located partial drawings, extracting the reinforcement information layers for each component type according to business requirements, and then performing information recognition on the extracted layers to obtain reinforcement quantity information containing 3D volume information. During layer extraction, reinforcement information can be extracted for a single type of component or for multiple types of components.

[0068] Step S4: Match and fill the steel reinforcement quantity information with the three-dimensional initial quantity calculation model to generate the target engineering quantity information.

[0069] During matching, the primitives in the 3D initial quantity calculation model are traversed, and the reinforcement quantity calculation information is loaded. The primitives in the GTJ terminal 3D initial quantity calculation model that are on the same floor, of the same component type, and in the same location as the reinforcement quantity calculation information are selected as the matching results of the corresponding primitives in the GTJ terminal 3D initial quantity calculation model. The corresponding reinforcement quantity calculation information is then updated to the corresponding primitives in the 3D initial quantity calculation model to complete the update of the reinforcement information and finally obtain the target engineering quantity information.

[0070] Optionally, step S4 may include steps S41 to S44, wherein:

[0071] Step S41: Traverse the graphic element information in the three-dimensional initial quantity calculation model and match the steel reinforcement quantity calculation information with the type and location information of each graphic element.

[0072] Step S42: If the matching is successful, fill the reinforcement quantity calculation information into the primitive information of the three-dimensional initial quantity calculation model;

[0073] Step S43: If the matching fails, the local drawing to which the rebar quantity calculation information belongs is repositioned, and the layers are extracted and the information is identified to obtain new rebar quantity calculation information. The new rebar quantity calculation information is then matched with each element information again, and the successfully matched new rebar quantity calculation information is filled into the element information of the three-dimensional initial quantity calculation model.

[0074] Step S44 continues until all steel reinforcement quantity information is matched, generating the target project quantity information.

[0075] Through the above operations, the design model is exported and imported into GTJ to complete the model reverse construction. The reinforcement information is supplemented by 3D design model recognition and reinforcement information matching to obtain a GTJ 3D quantity calculation model including civil engineering and reinforcement information. The mature quantity calculation capabilities of GTJ quantity calculation software are reused to complete the engineering quantity calculation and summary.

[0076] In this embodiment, the conversion from a 3D design model to a 3D quantity calculation model solves the problem of universal conversion between models from different design software, making the basic data that make up the 3D quantity calculation model more accurate. Simultaneously, the identification of reinforcement information in 2D CAD drawings supplements the identification data of the 3D design model, improving the composition of the basic data. By fusing the data from these two dimensions, the target engineering quantity information is finally generated, coordinating the design and quantity calculation work, avoiding the time waste and errors introduced by the formwork conversion process, and completing the quantity calculation of non-modeled reinforcement components, improving the efficiency and accuracy of the quantity calculation process, and reducing costs. Based on this application, the technical problem of low efficiency and accuracy caused by formwork conversion and quantity calculation using CAD drawings is solved. By supplementing the identification of the 3D design model and the reinforcement information in the 2D CAD drawings, the accuracy of engineering quantity calculation is improved.
