As shown in fig. 1, the present invention provides a material monitoring method, including:
step S1, classifying the component family library;
step S2, encoding the members in each classification based on the classification;
and step S3, labeling the codes to corresponding positions on the BIM data model of the material.

As shown in fig. 1, the BIM resource library of the e-commerce company is composed of a component (family) library, a process node library, a material library, a project inventory library and a template library.
In terms of family classification criteria: the classification method of the family library includes classification by speciality, classification by use stage, classification by family source, and the like. According to the scheme requirement that the purchase list style with material coding information can be derived after the BIM model is completed, considering that the family library is associated with the material codes, the method selects to adopt the classification according to the specialties, namely building, structure, electromechanics, fire fighting, power, civil air defense facilities and the like. The concrete steps can be shown in the following table 1:
TABLE 1
In an embodiment of the material monitoring method of the present invention, in step S1, the classifying the component family library includes:
classifying the member family library from top to bottom as: family library, specialty, category, family, and type.
Here, the family library classification system is, from top to bottom: family library-professional-category-family-type. For example: clan storehouse-fire control-fire alarm bell-fire light alarm-standard.
In the aspect of identification data of the family, attributes such as the category, specification, model and the like of the family are required to correspond to actual material information, and the specific operation method can be that the type of the family is clicked when the family is made, and the parameter of the variable characters such as the category, specification, model, manufacturer, material, description and the like is added.
The manufacturing criteria for a family should include the following sections: family templates, naming standards, positioning standards, visibility settings, parameter naming standards, etc.
The family category can be determined by the function of the family created, such as: mechanical equipment, a spray head, an air pipe fitting and the like, then a corresponding family template is selected, and then corresponding setting is carried out in family parameters. For example, an air pipe fitting and a 90-degree elbow are to be established, the group type is determined to be 'air pipe fitting', the group sample plate is 'metric air pipe elbow', and the group parameters are as follows: the part type or component type should be "elbow". If no similar family template can be found, a similar family can be found, modified therein, or a "metric routine model" can be used as a template.
The location of the family may be determined by three reference planes, coordinates (0,0,0), within the family document, the default three reference planes being: the reference altitude, the center (left/right), and the center (front/rear) are strictly defined by three reference planes in which the attribute "definition origin" is "check".
There are two types of family orientation: one is independent positioning and the other is combined positioning. For example, a device family, when the upper device instance is placed in the project document, the clicked position on the plane is the origin position of the device family; the combined positioning is typically a pipe connector family, such as a water pipe elbow family, the origin in the family document is the intersection point of the extension lines of the pipes corresponding to the two ends of the elbow, the elbow is generally automatically generated when the pipe is drawn after being set in the pipe arrangement configuration, the origin is determined by the intersection point of the two lines, and if the origin of the family has a problem, the family can display an exception on the project.
The primitives in the family mainly comprise two model primitives and annotation primitives, and the visibility setting of the family primitives comprises three types: the 'visible' in the primitive attribute can be switched on and off permanently or appointed to be switched on and off under certain conditions through a formula; secondly, a permanent switch is carried out on the model or the annotation primitive in a view → visibility/graphics dialog box; thirdly, performing related setting in the primitive attribute visibility/graph replacement; fourth, it is defined by family type parameters, which mainly apply to nested primitives.
Visibility settings within a family are mainly through a first and a third type, the former is mainly applied to the condition that the visibility of a primitive is influenced by the environment of a project, and the latter is relatively frequently applied and has relatively more parameters. Two points need to be noted here: firstly, in order to ensure the drawing effect and meet the legend of the Chinese building construction standard, symbol primitives based on a two-dimensional view are required to be drawn; and secondly, in order to ensure the normal display of the symbol graphic elements in the two-dimensional view, the plane/ceiling plane view in the visibility/graph needs to be set to be in a non-checking state on all three-dimensional graphic elements or other graphic elements.
In an embodiment of the material monitoring method of the present invention, step S1, after classifying the component family library, further includes:
the components in the component family library are associated with corresponding materials in the materials library.
Here, the material library, i.e., the material of the material, is associated with the member family library of the family.
(1) The material table can be counted according to the actual material, including information such as material name, material model, material parameters and the like.
(2) Or modifying or adding new material in the software material library according to the existing material table, and requiring that the information of the appearance, physical property, material model, parameter and the like of the material is consistent with the material table.
In the aspect of material manufacturing, a material library is opened, materials are newly built, and the names of the materials are consistent with the names of the materials. Material information consistent with the material table of the material, such as name, description, category, manufacturer, cost, etc., is entered in the identification column. And then the figure and the appearance of the material are modified to be consistent with the actual material.
In an embodiment of the material monitoring method of the present invention, after associating the component in the component family library with the corresponding material in the material library, the method further includes:
and establishing a corresponding project amount inventory library based on the related components in the component family library and the corresponding materials in the material library.
The engineering quantity list can be automatically realized in Revit, and the value of the engineering quantity list needs to be established on the basis of modeling precision, perfection of a component family library and perfection of a material library, so that the establishment of the engineering quantity list library is arranged behind the family library and the material library.
The engineering quantity inventory library is shown in a form of a detailed table in Revit, and a field is an attribute of a member, wherein the attribute can be counted only by sharing parameters, so that the member parameters can be counted only by setting the sharing parameters when a family is made.
And establishing a unified normal form of fields, filters, sorting/grouping, formats and appearances in the detail list to standardize the list library.
Detail sheet creation process such as
(1) "View" - "Diangzhen/quantity";
(2) selecting detail objects to be exported, such as windows, doors, walls and the like, and clicking for determination;
(3) selecting needed parameters in the optional column, and clicking 'adding';
(4) sequentially adding the group and type, the width, the height and the total, and if other parameters are required to be continuously added according to the requirement, editing the detailed list parameters and transversely sorting through deleting, moving up, moving down and the like;
(5) clicking 'calculation value' to edit area calculation, inputting a name, changing the type into 'area', selecting 'width' to input 'number in a formula column, then selecting height to obtain a calculation formula of' width 'and height', and clicking to determine;
(6) clicking 'sorting/grouping', selecting 'family and type' in a sorting mode, and 'listing each instance item by item' to cancel checking;
(7) clicking to determine to obtain a preliminary list, wherein the unit and the precision of the area do not meet the requirements, one column of the area can be selected, and a format unit is clicked in a menu column;
(8) and (4) canceling the use item setting, adjusting the related options, and clicking to determine.
(9) The list generated by the above method is for the whole project, if the list of a single standard layer needs to be generated, the list can be set by a filter, and the method is as follows: the "elevation" parameter continues to be added in the attribute column.
(10) Clicking the filter, sequentially selecting 'elevation' -equal to 'F3' (one elevation of the standard layer) in the filtering condition, and clicking to determine, thereby generating the window detail only aiming at the F3 standard layer.
(11) The Excel table can not be directly exported from the detail table in Revit, and only the TXT format can be exported firstly, and then the TXT file is opened by Excel to be stored as the Excel table.
(12) Or installing a RevitBus plug-in, and directly exporting the Excel table by using the detail table export function.
In an embodiment of the material monitoring method of the present invention, step S2, encoding the members in each category based on the categories includes:
performing corresponding four-level coding on the components in each classification based on the classification, wherein the four-level coding sequentially comprises: the system comprises a first-level large type, a second-level classification, a third-level classification and specification models, wherein the specification models comprise characteristic items and corresponding characteristic values.
In the method, through accurate classification and qualitative of material codes, reliable purchase price data can be provided for each important decision of group leaders and the decision of various operation behaviors. And basic data and value-added services are provided for the subsequent opening of third-party applications of the e-commerce platform. The method realizes the association of material codes and BIM basic family libraries, promotes the development of group BIM, subdivides project cost, accelerates the cost estimation speed, improves the cost estimation accuracy and services the information construction of the group.
