Description

Technical Field

[0001] The present invention relates to the technical field of three-dimensional design, and in particular to a decoration modeling method based on a BIM model. Background Art

[0002] BIM model is the abbreviation of Building Information Modeling, which is a digital tool used in building design, construction and management. It is based on three-dimensional digital technology and simulates the real information of buildings by integrating detailed data of various relevant information of construction projects. It has the advantages of visualization, coordination and simulation.

[0003] The conventional operation mode of the current decoration industry is that designers first build decoration models in a non-construction environment and hand over these designs to the construction team in the form of drawings for execution. However, in the actual construction process, due to various unexpected conditions that may occur on site, the construction team often needs to flexibly adjust the decoration plan and notify the designers to come to the site for on-site inspection and processing.

[0004] The problem is that design models are usually highly integrated and interrelated, and any local changes may affect the structure and balance of the entire model. Therefore, designers often face great difficulties and challenges when modifying models on site, and the construction of new models also requires considerable time and effort.

[0005] At the same time, decoration projects usually have strict time node requirements. The complexity, diversity and variability of the construction site, coupled with the differences in construction capabilities among different construction teams and the different levels of understanding of design drawings or models, all increase the uncertainty and risk in the decoration process.

[0006] Under the combined effect of these factors, designers often face pressure and compromise requirements from the construction team. Such compromises may make it difficult to control the quality, cost and accuracy of decoration, and may even exceed the original expectations and controllable range.

[0007] In order to optimize this process and reduce the occurrence of problems, it is necessary to improve the flexibility and adjustability of the design model. Therefore, a decoration modeling method based on BIM model is proposed. Summary of the invention

[0008] The purpose of the present invention is to provide a decoration modeling method based on a BIM model to solve the problems described in the background technology.

[0009] The technical solution of the present invention is achieved in this way:

[0010] A decoration modeling method based on a BIM model, comprising the following methods:

[0011] Step S1, establishing a database, calling interactive software and a target folder in a cloud server;

[0012] Step S2, setting the file naming and storage format in calling the interactive software;

[0013] Step S3: using modeling software on the terminal device to establish a corresponding basic model and form a basic file according to the preset decoration materials and decoration site, and store it in the database by calling the interactive software;

[0014] Step S4, exporting the basic file from the database by calling the interactive software on the terminal device, and using the modeling software on the terminal device to combine the basic model to establish the preset decoration model V1.0, forming the preset decoration model V1.0 into the preset decoration basic file V1.0 and uploading it to the database by calling the interactive software;

[0015] Step S5: During the acceptance of decoration materials and decoration sites, a modeling software is used on the terminal device to establish a corresponding comparison model for the actual decoration materials and decoration sites and form a comparison file, which is stored in the database by calling the interactive software;

[0016] Step S6: Use the modeling software on the terminal device to import the comparison file into the preset decoration basic file V1.0, first compare the difference between the actual decoration site and the preset decoration model V1.0, and process the difference to form the preset decoration model V2.0, and form the preset decoration basic file V2.0 from the preset decoration model V2.0 and upload it to the database by calling the interactive software;

[0017] Step S7, based on the preset decoration model V2.0, compare the actual decoration material model with the preset decoration model V2.0, and form the preset decoration model V3.0 after processing the difference, and form the preset decoration model V3.0 into the preset decoration basic file V3.0 and upload it to the database by calling the interactive software.

[0018] A further technical solution is that in step S3, the modeling software is used on the terminal device to establish a corresponding basic model and form a basic file according to the preset decoration materials and decoration site, and the specific steps of storing it in the database by calling the interactive software are as follows:

[0019] Step S31: according to the design appearance and size of the decoration material, a proportional object design model is established using modeling software to form a physical basic file, and the physical basic file is named, the naming correctness is checked, and stored in the database by calling the interactive software;

[0020] Step S32: according to the preset size of the decoration site, use the modeling software to establish a proportional site design model, thereby forming a site basic file, and by calling the interactive software, name the site basic file, check the correctness of the naming, and store it in the database.

[0021] A further technical solution is that the specific steps of exporting the basic file from the database by calling the interactive software on the terminal device in step S4 are:

[0022] S41, connecting to the cloud server on the terminal device and using the interactive software to search for the required physical basic files and site basic files, and transferring the target physical basic files and site basic files into the target folder;

[0023] S42, copying the target basic file in the target folder to the terminal device.

[0024] A further technical solution is that in step S4, the modeling software is used on the terminal device to combine the basic model to establish the preset decoration model V1.0, and the preset decoration model V1.0 is formed into a preset decoration basic file V1.0 and uploaded to the database by calling the interactive software. The specific steps are:

[0025] Step S43: Use modeling software on the terminal device to import the site basic file to release the site design model, and then gradually import the physical basic file into the site design model to form all the basic models required by the preset decoration model V1.0;

[0026] Step S44, by moving the object design model to the preset position of the site design model in the modeling software, the preset decoration model V1.0 is quickly combined to form a preset decoration basic file V1.0, and the decoration basic file is named, the naming correctness is checked and stored in the database by calling the interactive software.

[0027] A further technical solution is that in step S5, during the decoration material acceptance and decoration site acceptance process, a modeling software is used on a terminal device to establish a corresponding comparison model for the actual decoration materials and decoration site and form a comparison file, and the specific steps of storing the comparison file in a database by calling the interactive software are as follows:

[0028] S51. During the acceptance of materials for decoration construction, a modeling software is used to build a proportional physical model of the items according to the actual appearance and size of the decoration materials, thereby forming a physical comparison file, and the physical comparison file is named, the naming correctness is checked, and stored in the database by calling the interactive software;

[0029] S52. During the site acceptance process before the decoration construction, a proportional physical model of the site is established using modeling software based on the actual measured dimensions of the decoration site, thereby forming a site comparison file. The site comparison file is named, the naming correctness is checked, and stored in the database by calling the interactive software.

[0030] A further technical solution is that the specific steps of step S6 are:

[0031] S61, connecting to the cloud server on the terminal device and using the interactive software to search for the required preset decoration basic file V1.0, physical comparison file and site comparison file, and transferring the target preset decoration basic file V1.0, physical comparison file and site comparison file into the target folder;

[0032] S62, copying the target file in the target folder to the terminal device;

[0033] S63, using the modeling software on the terminal device to first import the preset decoration basic file V1.0 to release the preset decoration model V1.0, and then import the site comparison file into the underlying model to release the site physical model;

[0034] S64, moving the site physical model to the standard point of the site design model in the preset decoration model V1.0, so that the site physical model and the site design model overlap, so as to quickly compare the difference between the two, and use the interference check function of the modeling software to perform interference check on the site physical model and other object design models to obtain the inspection result;

[0035] S65. According to the comparison difference results and the inspection results, the assembly relationship between the object design model and the site physical model is readjusted in the preset decoration model to eliminate the interference effect, and the preset decoration model V2.0 is obtained to form the preset decoration basic file V2.0. The decoration basic file is named, the naming correctness is checked, and stored in the database by calling the interactive software.

[0036] A further technical solution is that in step S7, based on the preset decoration model V2.0, the actual decoration material model is compared with the preset decoration model V2.0, and the preset decoration model V3.0 is formed after processing the difference, and the preset decoration model V3.0 is formed into a preset decoration basic file V3.0 and uploaded to the database by calling the interactive software. The specific steps are:

[0037] S71. Based on the preset decoration model V2.0, the physical comparison file is gradually imported, the physical model of the object is released, and the physical model of the object is moved to the standard point of the corresponding object design model, so that the physical model of the object and the object design model overlap, so as to quickly compare the difference between the two, and use the interference check function of the modeling software to perform interference check on the site physical model and the object physical model to obtain the inspection result;

[0038] S72. According to the comparison difference results and the inspection results, the assembly relationship between the physical model of the object and the physical model of the site is readjusted in the preset decoration model V2.0 to eliminate the interference effect, obtain the preset decoration model V3.0, form the preset decoration basic file V3.0, and name the decoration basic file by calling the interactive software, check the naming correctness and store it in the database.

[0039] The beneficial effects of the present invention are:

[0040] Through the above method, two basic models can be established in advance, one is the preset decoration model V1.0, and the other is the preset decoration model V2.0. Through the construction of these two models, it can help designers quickly sort out the factors that cause the change after the decoration site changes. In large-scale decoration construction, it is carried out in parallel with multiple lines rather than a single line, including the gradual construction of the decoration site, the gradual selection, customization, purchase, and even processing of decoration materials, the gradual transportation and acceptance of decoration materials, the resignation and entry flow of designers, and the change of the construction team. In this process, the decoration modeling method of the present invention can form an effective unified method, gradually update the physical basic files, physical comparison files, site basic files, and site comparison files required for modeling, and timely update the model status according to the progress of construction, so as to better control all aspects of decoration.

[0041] When decoration modeling is actually applied to physical decoration, designers can quickly and locally change the decoration modeling based on the temporary suggestions of the construction team, analyze the interference caused by the changes, and generate the corresponding V3.0 version for other designers to learn from and refer to. Ultimately, it enables fast and effective communication between designers and the construction team, thereby strictly controlling the quality, cost and accuracy of decoration.

[0046] In order to better understand the technical content of the present invention, specific embodiments are provided below, and the present invention is further described in conjunction with the accompanying drawings.

[0047] A decoration modeling method based on a BIM model, comprising the following methods:

[0048] Step S1, establishing a database in the cloud server, calling interactive software and a target folder.

[0049] Step S2: setting the file naming and storage format in calling the interactive software.

[0050] The purpose of setting up the calling interactive software is to limit the users and ensure that the design files can be stored in the database with the correct naming format, so that the users can quickly call the required design files from the database and quickly copy these design files to the target folder, so that the users can uniformly retrieve the required design files in the target folder.

[0051] See also Figure 1 to Figure 2 , provides an implementation of an interactive software interface on how to ensure that design files can be stored in the database in the correct naming format. This is a basic HTML and JavaScript implementation example that creates an interactive interface that includes the following usage logic:

[0052] 1. Provide customers with an interactive interface with a virtual button for "Save File";

[0053] 2. When the customer clicks the virtual button "Save File" on the interactive software interface, the interactive software pops up the "Input Interface";

[0054] 3. The "input interface" displays example characters of the file naming rules, such as "venue-A5-2nd floor-area C-C01-design size-20230817", "item-PVC water pipe-80*2000-design size". It should be noted that only one naming rule is shown here, and the specific situation needs to be formulated according to different decoration projects. The "input interface" also provides an "input box". The "input box" is used by customers to name the files to be stored. The "input interface" also provides a virtual "upload" button. Click the virtual "upload" button to pop up a pop-up box for file upload. Customers select the files to be uploaded in the pop-up box and click confirm to return to the "input interface". The "input interface" also provides a virtual "save in database" button. When the customer clicks the virtual "save in database" button, the interactive software checks the file name in the "input box" to ensure whether it complies with the naming rules. If it complies with the naming rules, it checks whether the uploaded file exists. If the uploaded file exists and the naming rules are met, the file is named with the characters in the "input box" and stored in the database. If it does not comply with the naming rules, a 2-second error prompt picture will pop up on the "input interface". If the file does not exist, a 2-second error prompt picture will pop up on the "input interface".

[0055] Figure 1 and Figure 2 The code contains the necessary buttons and input boxes. It should be noted that this example only contains front-end code and does not involve actual file upload or database storage logic, which usually requires back-end services to handle.

[0056] This code creates a basic interactive interface, including a "Save File" button and an "Input Interface" that is initially hidden. Clicking the "Save File" button displays the "Input Interface", where the user can enter the file name and click the "Upload" button to select the file. Once the file is selected, the "Save to Database" button becomes available. Clicking the "Save to Database" button will trigger file name validation and file existence check. If both pass, relevant information will be printed in the console (in actual applications, this should be the logic of sending requests to the backend to handle file uploads and database storage). If the file name does not meet the rules or no file is selected, an error message will be displayed. The error message will be automatically hidden after 2 seconds.

[0057] Please note that the validateFileName function in this example uses a very simple regular expression to validate the file name. Customers need to adjust this regular expression according to the actual naming rules. In addition, this example does not actually implement file upload and database storage, which usually require backend service support. In actual development, you can choose to use AJAX, Fetch API or other technologies to communicate with the backend service.

[0058] Step S31: according to the design appearance and size of the decoration material items, use the modeling software to build a proportional item design model to form a physical basic file, and call the interactive software to name the physical basic file, check the correctness of the naming, and store it in the database.

[0059] Step 32: according to the preset size of the decoration site, use the modeling software to establish a proportional site design model, thereby forming a site basic file, and by calling the interactive software, name the site basic file, check the correctness of the naming, and store it in the database.

[0060] When using modeling software, there are many modeling software with similar functions that can be used, such as CATIA and SOLIDWORKS. Here, SOLIDWORKS is used as an example. In SOLIDWORKS, select the same base surface to create the object design model and the site design model, and save them in .SLDPRT format.

[0061] See also Figure 3 Here is a simple example code, using Python's Flask framework as the backend service, which can receive files and file names sent by the frontend, further verify and process the received data, rename the files according to the received file names and save them to the specified location on the server, and finally store the file information (such as file path, file name, etc.) in the database. It should be noted that this example only represents one implementation path of this function. Technicians can also use more complex database systems (such as MySQL, PostgreSQL) to replace SQLite to achieve more details and functions. These technical means are also feasible technical means and will not be described in detail here.

[0062] Step S41, connecting to the cloud server on the terminal device and using the calling interactive software to search for the required physical basic files and site basic files, and transferring the target physical basic files and site basic files into the target folder.

[0063] The above interactive interface also provides a virtual button of "Search File". After clicking the virtual button of "Search File", a "Search Box" pops up. The "Search Box" includes a "Text Input Box" for customers to input characters and a "Search" virtual button. After clicking the "Search" virtual button, instructions are sent to the backend database according to the characters in the "File Input Box". It should be noted that in Figure 1 , Figure 2 Under the inspiration of the code, adding functions such as the search file button is a common code writing procedure, which will not be given in detail here. Relevant technicians can use conventional codes to implement the above functions.

[0064] Step S42: copy the target basic file in the target folder to the terminal device.

[0065] See also Figure 4 , use Python's built-in libraries os and shutil to handle file and folder operations. The following is a basic Python script example to implement the implementation method of calling the target file from the database of the cloud server to the target folder. It should be noted that data matching and debugging are required between the above-mentioned back-end software and the previous front-end software. These are existing technical means that can be implemented by those skilled in the art and will not be described in detail here. The above implementation method only shows a feasible solution, and does not mean that the file retrieval solution is the only solution. Those skilled in the art can also use other software to implement the functions required by the present invention.

[0066] Step S43, use the modeling software SOLIDWORKS on the terminal device to create an assembly, and import the site basic file to release the site design model to form the bottom layer of the assembly, and then gradually import the physical basic file into the site design model to form all the basic models required for the preset decoration model V1.0.

[0067] Step S44, by moving the physical object design model to the corresponding position of the site design model in the modeling software SOLIDWORKS, and setting the assembly method of the physical design model through the "matching" instruction card, when multiple repeated physical design models are needed, the physical design models can be quickly copied and pasted in the "design tree" on the left side of the software, and quickly arranged, so as to quickly combine the preset decoration model V1.0, form the preset decoration basic file V1.0, and name the decoration basic file by calling the interactive software, check the correctness of the naming, and store it in the database.

[0068] Step S51: During the acceptance of materials for decoration construction, a proportional physical model of the items is established using the modeling software SOLIDWORKS according to the actual appearance and size of the decoration materials, thereby forming a physical comparison file, and the physical comparison file is named, the naming correctness is checked, and stored in the database by calling the interactive software;

[0069] Step S52: During the site acceptance process before the decoration construction, a proportional physical model of the site is established using the modeling software SOLIDWORKS according to the actual measurement size of the decoration site, thereby forming a site comparison file, and the site comparison file is named, the naming correctness is checked, and stored in the database by calling the interactive software;

[0070] Step S61, connecting to the cloud server on the terminal device and using the interactive software to search for the required preset decoration basic file V1.0, physical comparison file and site comparison file, and transferring the target preset decoration basic file V1.0, physical comparison file and site comparison file into the target folder;

[0071] Step S62, copying the target file in the target folder to the terminal device;

[0072] Step S63: on the terminal device, first import the preset decoration basic file V1.0 into the modeling software SOLIDWORKS to release the preset decoration model V1.0, and then import the site comparison file into the underlying model to release the site physical model;

[0073] Step S64, move the site physical model to the standard point of the site design model in the preset decoration model V1.0, so that the site physical model and the site design model overlap, so as to quickly compare the difference between the two by visual inspection, and use the "interference detection" command function in the "evaluation" tab of the modeling software SOLIDWORKS to perform interference inspection on the site physical model and other object design models, and obtain visual inspection results, so as to compare and obtain the assembly difference between the actual built site and the target decoration items at a glance, and have a high-level conceptual understanding of the decoration situation in the area;

[0074] Step S65: According to the comparison difference result and the inspection result, the assembly relationship between the object design model and the site physical model is re-adjusted in the preset decoration model to eliminate the interference effect, and the preset decoration model V2.0 is obtained to form the preset decoration basic file V2.0, and the decoration basic file is named, the naming correctness is checked, and stored in the database by calling the interactive software;

[0075] Designers can use the "Measure" command in the "Evaluation" tab of the modeling software SOLIDWORKS to mark the distance parameters between various points, lines, and surfaces in the decoration space, and issue a plane design drawing at each angle. When decorating, the decoration team can perform actual operations based on the preset decoration model V2.0, which can reduce operational errors and obtain a visual multi-angle decoration schematic diagram, thereby increasing the decoration speed.

[0076] Step S71, when the decoration team encounters a large difference between the physical objects used for decoration and the object design model in the preset decoration model V2.0 during the decoration process, the designer can import the corresponding physical comparison file on the basis of the preset decoration model V2.0 according to the needs, release the physical model of the object, and move the physical model of the object to the standard point of the corresponding object design model, so that the physical model of the object and the object design model overlap, so as to quickly compare the difference between the two, and use the interference check function of the modeling software to check the interference between the physical model of the site and the physical model of the object, and obtain the inspection results, so as to quickly and intuitively obtain the effect picture after the application of the physical decoration, avoiding the confusion of various parameters caused by redrawing. The new effect picture will be used to guide the decoration team to carry out decoration. The decoration team can intuitively see the decoration results from the three-dimensional model on site, and can raise new questions at any time based on the re-updated model, which speeds up the recognition and overlap of the design concepts of designers and construction personnel, thereby speeding up the construction progress.

[0077] Step S72, according to the comparison difference results and the inspection results, readjust the assembly relationship between the physical model of the object and the physical model of the site in the preset decoration model V2.0 to eliminate the interference effect, and obtain the preset decoration model V3.0, or multiple derivative models based on V3.0, to form a preset decoration basic file V3.0, or other V3.1, V3.2 and other multiple files, and name the decoration basic file by calling the interactive software, check the correctness of the naming, and store it in the database, so that it can be quickly called when the construction site is changed later, without re-modeling.

[0078] Application principle of the present invention:

[0079] Through the above method, two basic models can be established in advance, one is the preset decoration model V1.0, and the other is the preset decoration model V2.0. Through the construction of these two models, it can help designers quickly sort out the factors that cause the change after the decoration site changes. In large-scale decoration construction, it is carried out in parallel with multiple lines rather than a single line, including the gradual construction of the decoration site, the gradual selection, customization, purchase, and even processing of decoration materials, the gradual transportation and acceptance of decoration materials, the resignation and entry flow of designers, and the change of the construction team. In this process, the decoration modeling method of the present invention can form an effective unified method, gradually update the physical basic files, physical comparison files, site basic files, and site comparison files required for modeling, and timely update the model status according to the progress of construction, so as to better control all aspects of decoration.

[0080] When decoration modeling is actually applied to physical decoration, designers can quickly and partially change the decoration modeling based on the temporary suggestions of the construction team, analyze the interference caused by the changes, and communicate quickly and effectively with the construction team, so as to strictly control the decoration quality, cost and accuracy.

[0081] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

The decoration modeling method based on the BIM model according to claim 5 is characterized in that: In step S7, the actual decoration material model is compared with the preset decoration model V2.0 based on the preset decoration model V2.0, and the preset decoration model V3.0 is formed after the difference is processed. The preset decoration model V3.0 is formed into a preset decoration basic file V3.0 and uploaded to the database by calling the interactive software. The specific steps are: S71. Based on the preset decoration model V2.0, the physical comparison file is gradually imported, the physical model of the object is released, and the physical model of the object is moved to the standard point of the corresponding object design model, so that the physical model of the object and the object design model overlap, so as to quickly compare the difference between the two, and use the interference check function of the modeling software to perform interference check on the site physical model and the object physical model to obtain the inspection result; S72. According to the comparison difference results and the inspection results, the assembly relationship between the physical model of the object and the physical model of the site is readjusted in the preset decoration model V2.0 to eliminate the interference effect, obtain the preset decoration model V3.0, form the preset decoration basic file V3.0, and name the decoration basic file by calling the interactive software, check the naming correctness and store it in the database.
