Description

Technical Field

[0001] The present invention belongs to the technical field of three-dimensional digital design, and specifically is a method for adding BIM attributes to a model and outputting a BIM attribute table. Background Art

[0002] BIM is the abbreviation of Building Information Modeling. It was first proposed by the construction industry and gradually expanded to the entire engineering construction field. BIM model refers to a model with geometric attributes and non-geometric attributes and information. At present, the attributes of BIM model are roughly divided into geometric attributes and non-geometric attributes. Geometric attributes can be viewed and read based on the model results, and non-geometric attributes need to be entered by designers at various stages of engineering design.

[0003] However, the existing models do not have any attribute information except geometric attributes. There are many BIM model building softwares, and the model formats as well as the methods and strategies of software parsing BIM attributes are different, which leads to incompatible conversion of BIM models on different platforms and loss of BIM attributes. Summary of the invention

[0004] The purpose of the present invention is to provide a method for adding BIM attributes to a model and outputting a BIM attribute table, so as to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solution: a method for adding BIM attributes to a model and outputting a BIM attribute table, comprising:

[0006] 1) Create a BIM standard data model;

[0007] 2) Add extended attributes to parts;

[0008] 3) obtaining a classification standard for structural components in the BIM model, wherein the classification standard is used to characterize corresponding properties of the structural components;

[0009] 4) Read the attribute information of BIM model components to form a first data list, and read all attribute information in the BIM standard data model to form a second data list

[0010] 5) Compare each component of the BIM model to be verified with the components in the BIM standard data model component library to check whether the components match;

[0011] 6) For each component that meets the matching conditions, attribute verification is performed based on the component attributes in the BIM model standard data model component library, and a BIM attribute table is output.

[0012] Preferably, an inspection batch attribute is added to the extended attributes and used as a time parameter identifier to form a time series in the text storage process.

[0013] Preferably, a BIM standard data model is established based on the engineering stage domain, component classification tree, attribute pool and component library.

[0014] Preferably, the data structure of the BIM standard data model is in the form of database, XML, EXCEL, or TXT document.

[0015] Preferably, the extended attributes include component type, component name, color, code, geometric size, and material.

[0016] Preferably, for each BIM model component to be verified, all BIM standard attributes associated with its matching BIM standard component are searched, and for each BIM standard attribute of the BIM standard component, the names of all attributes in the BIM model component to be verified are compared one by one. If the name of a certain attribute of the BIM model component to be verified is consistent with the name of the BIM standard attribute, then it is determined that the attribute of the BIM model component to be verified matches the BIM standard attribute, and the BIM model component to be verified has the BIM standard attribute; if no attribute of the BIM model component to be verified is consistent with the name of the BIM standard attribute, then it is determined that no attribute of the BIM model component to be verified matches the BIM standard attribute, and the BIM model component to be verified lacks the BIM standard attribute.

[0017] Preferably, the steps of the components that do not meet the standards are specifically displayed in the BIM attribute table by highlighting, marking or listing.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The purpose of the present invention is to provide a method for adding BIM attributes to a model and outputting a BIM attribute table, which can automatically verify whether the BIM model meets the standards, has high verification efficiency and accurate verification results, facilitates users to reshape the BIM model on a third-party platform and deeply apply the BIM model, and solves the loss of BIM attributes caused by differences in design platforms.
