[0029] Please refer to Figure 1 , Figure 1 The flowchart of the automatic assembly method based on BIM provided by the embodiments of the present application; as shown in Figure 1 , the method comprises steps S101-S104.

[0030] S101, creating a component family file by using Revit software, and performing parameterization processing on the component family file, and selecting corresponding IFC format to export the component family file to obtain a corresponding IFC data file;

[0031] S102, performing format analysis on the IFC data file to obtain a corresponding JSON file;

[0032] S103, import the pre-set quota information table as a data table into the JSON file, compile the JSON file into a new IFC data file, update the IFC data file, and input the updated IFC data file into the Revit software;

[0033] S104, after creating a building project in the Revit software, call the corresponding component family file, and based on the pre-set calculation rules, calculate the target quotation of each component and output the corresponding list quotation data.

[0034] In this embodiment, first, the component family file is created by applying Revit, and then the component family file is parameterized, for example, the vertical spacing of light steel keel and partition keel is set to 300mm, and when the corresponding partition wall length exceeds 300mm, vertical keel is automatically added, so that the spacing between the keels is maintained at a distance of 300mm, wherein the vertical keel is fixed with gypsum board, bottom plate and outer plate according to the process, and the spacing distance between adjacent gypsum board, bottom plate and outer plate is kept consistent, then the corresponding IFC format is selected to export the corresponding parameterized component family file, and the IFC data file of the BIM model is obtained.

[0035] It should be noted that in step S102, the IFC data adopts an entity relationship model defined by the EXPRESS language, which includes three-dimensional geometric model information and other information, and the description mainly includes type description (Type), entity description (Entity), rule description (Rule), function description (Function) and process description (Procedure).

[0036] Then, the corresponding format analysis file is written by Python, and the IFC data is parsed into a JSON file, so that the user can view the corresponding parameter relationship index.

[0037] Then, the conversion tool in Python is used to import the quota information table as a data table into the parsed JSON file to supplement the IFC data; in a specific embodiment, the quota information table includes the following field contents: number, sub-component name, specification, unit, unit price, market price, usage quantity, quota total price, market total price, material type; wherein each number corresponds to each sub-component name.

[0038] Then, the IFC data in the JSON file is compiled, and the entered JSON file is compiled into IFC data by Python, and the family model is entered into the system (Revit software) as a Revit family model, that is, the compiled component family file replaces the original component family file.

[0039] In actual use, the user creates a building project on the Revit software, then calls the corresponding (pre-set) component family file, regulates the length of the model, that is, automatically generates the corresponding building model (three-dimensional model) according to the regulation set by the parameterized component family file, and calculates the target quotation of each component based on the preset calculation rule, and finally exports the list quotation data.

[0040] The application realizes the functions of rapid quantity calculation and rapid group pricing by creating the analysis and application of IFC data in the BIM model and binding the quota information table and the three-dimensional model; has a simpler effect, can obtain the total price of the corresponding component sub-item project by analyzing the corresponding BIM model, and can obtain the list quotation through the cost platform; has a more convenient effect, because the unit price and the market unit price are bound to the BIM model, one-key output list quotation can be realized, and the operation is more convenient; has a more intelligent effect, the BIM component is bound to the quota and the information price, and through the setting of the front parameter, the computer can more intelligently complete the group pricing work of the list quotation; has a more accurate effect, the calculation quantity is automatically completed by the computer, the error of manual calculation is greatly reduced, and the automatic group pricing is also more standardized.

[0041] In a specific embodiment, the step S101 of "creating a component family file by using the Revit software and parameterizing the component family file" comprises:

[0042] S10, creating a component family file by using the Revit software, obtaining a corresponding parent component, and obtaining all sub-components corresponding to the parent component;

[0043] S11, creating a model corresponding to all sub-components, and parameterizing and storing the current parameters between the sub-components based on a preset parameter specification rule.

[0044] In this embodiment, for example, a light steel keel component family file is created according to a parent component such as a light steel keel model component, that is, a light steel keel model component (appearance) is created, wherein the light steel keel component model comprises the following sub-components: through keel, horizontal support keel, vertical keel, horizontal keel (ceiling and floor keel), support card, gypsum board, bottom plate, outer layer plate, and rivet.

[0045] After obtaining the complete light steel keel component, the light steel keel component is parameterized and adjusted based on a preset parameter specification rule, for example, for a light steel keel partition keel 75 series vertical spacing of 300 mm, the vertical keel is automatically added when the length of the corresponding partition wall exceeds 300 mm, and the vertical keel is fixed at the head and tail, wherein the gypsum board, the bottom plate and the outer layer plate are consistent with the size of the partition wall.

[0046] After the parameter adjustment is completed, the created component family file is saved.

[0047] In an embodiment, before the step S101 of "selecting an IFC format corresponding to the component family file to export the component family file to obtain an IFC data file", the step S101 further includes:

[0048] S20, adding a shared parameter code to the parent component based on a preset bill of quotation rule.

[0049] In this embodiment, the project shared parameter code is added to the parent component. According to the preset bill of quotation rule, the shared parameter code is B2-294 when the vertical spacing of the 75 series of light steel keel partition keel is 300 mm. Through such a setting, the user can call the corresponding component family file according to the shared parameter code, so that the final output bill of quotation data is the required quotation.

[0050] In an embodiment, the step S103 of "importing the preset quota information table into the JSON file as a data table" includes:

[0051] S30, generating a corresponding key-value pair based on the shared parameter code and establishing a mapping relationship between the shared parameter code and the corresponding key-value pair;

[0052] S31, entering cost resource information and material resource information in the key-value pair, wherein the cost resource information includes market unit price and quota unit price, and the material resource information includes usage quantity and material type;

[0053] S32, entering a corresponding function relationship in the key-value pair to obtain a calculation rule.

[0054] In this embodiment, for example, taking light steel keel as an example, the cost resource information and the material resource information of the light steel keel are obtained in advance. Specifically, the cost resource information and the material resource information can be shown in Table 1 as follows:

[0055] Table 1:

[0056]

[0057] The number in Table 1 corresponds to the number of each sub-component corresponding to the light steel keel, that is, each shared parameter code corresponds to a plurality of key-value pairs, for example, the shared parameter code B2-294 corresponds to the key-value pairs of the name, specification, unit, quota unit price, market unit price, quantity, quota total price, market total price and corresponding value, in this embodiment, the corresponding key-value pairs are entered into the IFC cost resource and material resource, the number is used as the mapping relationship, and the corresponding function relationship is entered, for example, for every 1 m increase of the wall, the U-shaped light steel keel of 38*40 increases by 14.14 m, the labor increases by 0.91 workdays, and the vertical keel is automatically calculated according to the parameter family creation rule, that is, for every 300 mm increase of the interval, one vertical keel is added, and the total price calculation rule is the corresponding quantity*unit price.

[0058] In a specific embodiment, the step S104 comprises:

[0059] S40, creating a building project, and selecting to import a corresponding component family file by using a wall drawing function in the Revit software;

[0060] S41, obtaining each sub-component in the component family file, and automatically generating a model corresponding to a parameter-processed sub-component based on a preset parameter specification rule;

[0061] S42, obtaining all field contents in the component family file by using a statistical table creation function in the Revit software, and according to a creation rule of the parameter family, counting the quantity in each field content, and automatically calculating a market total price and a quota total price based on the calculation rule;

[0062] S43, exporting all target quotations by using a report export function in the Revit software, to obtain a quotation file.

[0063] In this embodiment, a project is created by using the Revit software, and a light steel keel family file is applied, specifically: a general building project is created, a corresponding light steel keel family file is selected to be imported by using a wall drawing function in the Revit, a model with a required length is regulated, that is, a light steel keel partition wall (vertical 300 mm interval) is automatically generated according to a regulation rule of the parameterized family file; a statistical table creation function in the Revit software is used to automatically obtain information fields contained in the corresponding family file, which includes the field contents (each field content in the quota information table) entered in the step S103, and according to the wall length, that is, the parameter family rule, the quantity under the corresponding field is automatically counted, and the total price is automatically calculated according to the calculation rule. The market price can be uniformly entered by using an external tool when the quota information table is generated; a report export function in the Revit software is used, in a specific embodiment, the quotation file is a CSV or EXCEL format file, and it should be understood that the function of one-key output of the list quotation can also be realized by developing a plug-in.
