Description

Technical Field

[0001] The present invention relates to the field of building intelligentization and automation design, and in particular to an automatic marking method for detailed design drawings based on a BIM model. Background Art

[0002] In modern construction projects, steel structure design is a key link, and detailed design drawings are one of the important technical documents for steel structure construction. Traditional detailed design drawings mainly rely on manual annotation, which is not only time-consuming and labor-intensive, but also prone to unstable annotation quality due to differences in designer experience, which in turn affects construction efficiency and quality. With the gradual popularization of BIM technology, architectural design has entered a new stage of digitalization and intelligence, providing technical support for the development of automated annotation systems. However, the automatic annotation systems for detailed steel structure design drawings on the market still have problems such as insufficient annotation accuracy, incomplete component identification, and inflexible templates, which cannot meet the needs of complex steel structure projects.

[0003] Therefore, it is of great practical significance to provide an automatic annotation method for detailed design drawings based on the BIM model to realize the automation and standardized annotation of steel structure drawings, reduce manual intervention, and improve annotation efficiency and quality. Summary of the invention

[0004] The purpose of the present invention is to provide a method for automatically marking detailed design drawings based on a BIM model.

[0005] The object of the present invention is achieved in that: A method for automatically marking detailed design drawings based on a BIM model comprises the following steps: Step 1. Open the detailed design BIM software and open the automatic drawing annotation program. Set the relevant properties in the "System Settings" of the software. Click the "Run" button at the bottom of the software to annotate and output drawings, generate lists and IFC, or annotate separately.

[0006] Step 2. Select the component in the model or the drawing in the drawing list, select the "Drawing Annotation" function in the software and check the component type, click the "Run" button at the bottom, and the software will automatically create drawings based on the selected template and annotate the components.

[0007] Step 3. Select the drawing in the drawing list, select the "Drawing Output" function in the software, select the drawing to be output from the drawing list, click the "Run" button at the bottom, and the software will automatically generate the drawing for management.

[0008] Step 4. Select the components in the model, select the "Report Creation" function in the software, select the report to be output from the list, click the "Run" button at the bottom, and the software will automatically output the corresponding report file.

[0009] Step 5. Select the components in the model, select the "IFC Export" function in the software, set the relevant properties, and click the "Run" button at the bottom. The software will automatically output the IFC file.

[0010] Step 6. The software background will record the output drawing information and automatically generate a drawing ledger. In the "Drawing Ledger" function of the software, view the drawing ledger for each batch.

[0011] The component types in step 2 include the system automatically distinguishing component types through geometric information, size and position characteristics, identifying different component categories such as steel beams, steel columns, and steel wall panels, and storing them in designated categories according to component types; users flexibly adjust and create annotation templates according to project requirements, configure annotation rules for different components, and save different types of component templates for reuse, thereby meeting specific annotation requirements in complex projects.

[0012] The automatic annotation of drawings according to the selected annotation template in step 2 includes the system automatically calling the matching template from the template library based on the identified component type, standardizing the detailed information of sections, dimension lines, welds and elevations to ensure the uniformity and standardization of the drawings.

[0013] The drawing generation and management in step 3 includes the system automatically generating processing drawings and review drawings from the marked component drawings according to the set output path, and saving them in hierarchical categories by project name, sub-item batch, and drawing type.

DETAILED DESCRIPTION

[0020] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1 As shown, a method for automatically marking detailed design drawings based on a BIM model includes the following steps: Step 1. Open the detailed design BIM software and open the automatic drawing annotation program. Set the relevant properties in the "System Settings" of the software. Click the "Run" button at the bottom of the software to annotate and output drawings, generate lists and IFC, or annotate separately.

[0022] Step 2. Select the component in the model or the drawing in the drawing list, select the "Drawing Annotation" function in the software and check the component type, click the "Run" button at the bottom, and the software will automatically create drawings based on the selected template and annotate the components. Figure 2 shown.

[0023] The component types in step 2 include the system automatically distinguishing component types through geometric information, size and position characteristics, identifying different component categories such as steel beams, steel columns, steel wall panels, and storing them in designated categories according to component types; users flexibly adjust and create annotation templates according to project requirements, configure annotation rules for different components, and save different types of component templates for reuse, thereby meeting specific annotation requirements in complex projects.

[0024] The automatic annotation of drawings according to the selected annotation template in step 2 includes the system automatically calling the matching template from the template library based on the identified component type, standardizing the annotation of detailed information such as sections, dimension lines, welds and elevations, and ensuring the uniformity and standardization of the drawings.

[0025] Step 3. Select the drawing in the drawing list, select the "Drawing Output" function in the software, select the drawing to be output from the drawing list, click the "Run" button at the bottom, and the software will automatically generate the drawing for management. The drawing generation and management in step 3 includes the system automatically generating processing drawings and review drawings from the marked component drawings according to the set output path, and saving them by project name, sub-item batch, and drawing type. At the same time, it generates a drawing catalog and report list for subsequent search and management.

[0026] Step 4. Select the components in the model, select the "Report Creation" function in the software, select the report to be output from the list, click the "Run" button at the bottom, and the software will automatically output the corresponding report file.

[0027] Step 5. Select the components in the model, select the "IFC Export" function in the software, set the relevant properties, and click the "Run" button at the bottom. The software will automatically output the IFC file.

[0028] Step 6. The software background will record the output drawing information and automatically generate a drawing ledger. In the "Drawing Ledger" function of the software, view the drawing ledger of each batch, such as Figure 3 shown.

[0029] Design steps: System Settings Module Design content: In "System Settings", you can fill in project settings such as project name, sub-item name, batch, version number, etc. In "Process Definition", you can check the type of drawings to be output, whether they are review drawings or processing drawings; in "Drawing Properties", you can change annotation properties, such as annotation style, dimension line color size, font properties, etc.; in "Path Settings", you can set the format selection and save path settings for output content including IFC, reports, drawing formats, etc. In "Annotation Filter", you can filter annotations for specified part names or prefixes.

[0030] Drawing annotation module Design content: The user selects a specific component in the model or a specific drawing in the drawing list, and the software automatically annotates the component or drawing through the "drawing annotation" function. "Drawing annotation" is divided into component drawings, part drawings and layout drawings. For complex components, you can add and adjust annotation templates, configure annotation rules for different components, and save different types of component templates for reuse to meet specific annotation needs in complex projects. For complex component drawings or part drawings, the software system has also developed "auxiliary functions". These separate small tools can assist designers in semi-automatic drawing, which can greatly save efficiency.

[0031] Drawing output module Design content: The user selects a specified drawing in the drawing list, and the software outputs the corresponding drawing file through the "Drawing Output" function. You can set the output of the drawing, including modifying the drawing's file name, drawing number attribute, drawing frame size, and drawing scale and other attributes.

[0032] Report creation module Design content: The user selects the components in the model or reverses the components through the drawing list, selects the "Report Creation" function, selects the report type from the list, and the software automatically generates the component report.

[0033] IFC export module Design content: The user selects the components in the model or reverses the components in the drawing list, selects the "IFC export" function, sets the relevant properties and then outputs the IFC file to prepare for uploading the project information to the company's one-stop system platform. The IFC parameter setting module includes the output file path, file format, output type, object type, and additional attribute information.

[0034] Drawing Ledger Module Design content: The software records the output drawing information in the background and automatically generates a drawing ledger for subsequent management and query. Drawing types are divided into component drawings, parts drawings, and layout drawings, which are issued in various forms and divided into three categories: review drawings, processing drawings, and change drawings. The issuance ledger management aims to establish a content management page on the system that records the time, output person, output content, and output location of the output drawings.

[0035] Application Cases: The automatic annotation software for detailed design drawings has been successfully applied in 12 projects. Compared with traditional manual annotation, it reduces time consumption and improves annotation efficiency by more than 80%. Automatic annotation through standardized templates reduces annotation errors caused by human operation and reduces the error rate to below 1.2%.

[0036] Take the 3# project of Nanda Production and R&D Base as an example. This project is located in the southwest of Baoshan District, Shanghai, between the outer and middle ring roads, close to the city center, and the main structure is a six-story steel frame structure. The columns and beams of this project are connected in the form of column-beam brackets. There are 690 components with a total weight of 673 tons. The drawings of this project are annotated using automatic annotation software, which takes about 4 to 5 hours to complete. If it is manually annotated, it is estimated to take about 3 days. Taking the steel beam with the component number of the five-story main beam 3-5-ZL-17 as an example, the software annotation operation display effect is as follows: 1. Open the Tekla structures model of this project and select the component 3-5-ZL-17 to be annotated.

[0037] 2. Open the steel structure detailed drawing automatic annotation management system, then fill in the project name, sub-item name, processing flow and other information in the "System Settings", select the default standard drawing properties, and then select the path information for the drawings, reports and IFC files to be output.

[0038] 3. Select the option of component drawing-steel frame beam in "Drawing Annotation" and click "Run".

[0039] 4. The software will note "Steel Beam" in the view label of the front view and start automatically marking the drawing.

[0040] 5. Before marking, the software will delete useless views, part marks, dimension lines, etc. in the drawing, leaving only the front view of the component.

[0041] 6. The software selects the steel frame beam adjustment annotation template based on the selected component type, and then creates an AA top view section in the main view according to the settings in the steel frame beam template. The view ratio of the top view is consistent with the size ratio of the front view; the software will create a section at the location of the connecting plate in the front view based on the component feature attributes. The part marks at the BB and CC sections in the drawing are different, and their respective section views are created separately. The same part marks will not be created and the size ratio of the section will also be consistent with the main view.

[0042] 7. The software creates the front view, AA top view section and node detail section according to the annotation template, and creates the overall dimension line, plate location line, bolt hole location line and part mark, bolt mark and other information of each part in the component in the view.

[0043] 8. After the annotation of each view is completed, the software will automatically adjust the scale of each view according to the size of the drawing label and the position of the material table. After adjusting to the appropriate size, the software will automatically arrange the views according to the annotation template.

[0044] 9. Marking is completed.
