Example 1
An automatic refining method of a BIM model mainly comprises the following steps of automatically refining three resources:
extracting unique components of the archived BIM model, extracting a project template of the archived BIM model, and extracting project sharing parameters of the archived BIM model.
Next, specific automatic refinements of these three resources will be described, respectively.
Firstly, extracting a specific component file of an archived BIM model:
the names and MD5 codes of all the first components after duplication elimination in the filed BIM model are obtained and matched with the names and MD5 codes of second components in the established enterprise component resource library to obtain unique components which are unique in the current BIM model and do not exist in the enterprise component resource library, a unique component resource warehousing auditing process is automatically initiated, the unique components after being audited are warehoused to the enterprise component resource library, and designers design and use the unique components.
It should be noted that the filed BIM model refers to a BIM model filed on the record after the collaborative design is finished, and the BIM model is a generating basis and a model delivery basis of a final drawing.
The component is a minimum three-dimensional data geometry and information unit formed by a BIM model, and is a minimum non-repeated item of a fixed value determined by a key attribute parameter or a plurality of key attribute parameter sets in the item.
The enterprise component resource library in the database is a plurality of component sets which meet the standard, and the enterprise component resource library reflected to the Autodesk Revit software is a plurality of loadable family file sets which meet the use standard.
The family is an element in modeling software and is also a carrier of parameter information, and the values corresponding to a plurality of attribute parameters of one family are possibly different to correspondingly form a plurality of family types.
MD5 codes are a cryptographic hash function widely used to generate a 128-bit (16-byte) hash value (hash value) to ensure the integrity and consistency of information transmission, and MD5 codes are unique. The naming standards and requirements of the components in the invention are as follows (the naming mode of the invention conforms to the national GB/T51269-2017 building information model component classification and coding standard):
1) the family name should indicate the content, version, status of the family.
2) With the purpose of accuracy and convenience, each professional names the target according to the existing use habit, and unnecessary redundant description is reduced.
3) Family names can be co-expressed by multiple Chinese fields as needed, and the total number of Chinese fields is no greater than 4. The fields are connected by an "_" symbol, and no spaces, other characters or symbols are used.
4) The year number represents the warehousing year of the family, 2 digits after the year are taken, and if 20 represents the family warehousing in 2020;
5) the serial number indicates the updated version of the family in the current year, and is indicated by English capital letters A-Z, and if 'B' indicates the second version of the family in the current year.
6) Specific naming modes and examples are as follows, and each specialty, each family, etc. may be referred to for naming:
A. formal family (family that is included in the enterprise component repository after being reviewed), naming principle is shown in fig. 7.
For example, structure _ concrete beam _ U-shape _ XN21A, furniture _ kitchen paper _ kitchen equipment _ refrigerator _ single-open refrigerator _ XN21B
B. Temporary family (family that was not incorporated into the enterprise component repository by examination), naming convention as shown in fig. 8.
For example, structure _ steel column _ H-shaped _ LDA8, structure _ concrete structure _ steel core concrete column _ circular _ LDA8.
As shown in fig. 1, in this embodiment, the specific steps of screening the unique components of the archived BIM model include:
a1, opening an archived BIM model, acquiring all family instances in the BIM model, acquiring families according to the family instances, removing repeated items of the families, acquiring family files according to the families, obtaining a component set of the current BIM model, namely a first component set, and acquiring names and MD5 codes of all first components in the first component set;
a2, acquiring the names and MD5 codes of all second building blocks in a second building block set in the enterprise building block resource library;
a3, traversing the names and MD5 codes of all the first building blocks and the second building blocks in the first building block set and the second building block set, comparing the name and MD5 code of each first building block with the name and MD5 code of the second building block in the second building block set, and determining whether the name and MD5 code of the first member is the same as the name and MD5 code of the second member set, if the name and MD5 code of the first member is the same as any one of the name and MD5 code of the second member set, then it is determined that the first building block already exists in the second building block set, a jump is made to a7, if the name and MD5 code of the first building block are different from the name and MD5 code of the second building block set, if the first component does not exist in the second component set, the first component is determined to be a special component, and the step is shifted to A4;
a4, standardizing and naming the special component according to temporary family resources, and adding the special component into an enterprise component resource temporary library;
a5, initiating a checking process, checking the special members in the enterprise member resource temporary library, and jumping to A6 after the checking is passed, otherwise, jumping to A7;
a6, naming the special components which pass the examination according to formal family, and putting the special components into an enterprise component resource library;
and A7, ending.
Due to the characteristics of large quantity and large variation of the components, the component name and the component file MD5 are coded into the first component and the second component for comparison, so that the situation of repeated creation of the same type of components can be effectively avoided, wherein the component name is coded according to a standardized naming mode, and the MD5 can prevent a user from modifying the component file name only on the basis of component encryption to repeat construction.
The MD5 code is a unique code of a BIM model component file, and is a unique code of a family file, and if the component is identified as a unique component after comparison, it means that the component is not in the existing enterprise component repository, but the same type of component exists in the enterprise component repository, and therefore, the parameter set and formula database of the component of the same type as the unique component in the enterprise component repository are bound with the unique component: the parameter set and formula database for the same type of component as the unique component in the enterprise component repository are written to the current unique component. The writing method is to perform secondary development writing on Revit.
Secondly, extracting the project template file of the archived BIM model:
extracting project template information (related information such as components, views and drawings) in the archived BIM model and forming a project template file, naming the project template file according to a standard naming mode, comparing the project template file with the project template file name in an established project template file resource library, if the project template file of the BIM model does not exist in the project template file resource library, automatically initiating a warehousing auditing process of the project template file in the current BIM model, and entering an enterprise project template file resource library after being audited by resource managers for resource reuse.
The project template is a template file which improves drawing efficiency, unifies drawing standards, ensures drawing quality, is prefabricated according to project characteristics before a project starts, and has both unity and particularity.
The enterprise template repository is a plurality of project template geometries which meet the use standard, and the Autodesk Revit software is reflected in a plurality of template file collections which meet the use standard and are in rte format.
The standardized naming convention for the project boilerplate is as follows:
1) for the project template file extracted from the filed BIM model, parameter comparison is carried out between the project template file and the template file name in an enterprise template resource library in a database so as to judge whether the project template file exists in the resource library;
2) after renaming, parameter modification and standardization are carried out on families which do not exist in a resource library sample plate library, a digital design resource review process is entered for uploading;
3) naming sample files extracted from items of the archived BIM model by adding item design numbers on the basis of the original naming rule for distinguishing, wherein the specific mode is as follows:
design number _ professional sign _ [ XX ] professional template + R + version number _ XN + release year + version
The extracted building specialty template as from the archived BIM model is named:
design number _ a _ building professional template _ R2019_ XN 20A.
The above is a standard naming mode, which is unique for an enterprise, and is a basis for judging whether templates in the BIM model already exist in the template file repository.
As shown in fig. 2, in this embodiment, the specific steps of extracting the item template of the archived BIM model include:
b1, opening the archived BIM model, and exporting the project template information of the archived BIM model to form a project template file;
b2, carrying out standardized naming on the exported project template file;
b3, extracting the project sample files operated in the step B2, comparing the project sample files with the file names of the project sample files in the sample file resource library, if the comparison is successful, judging that the project sample files exist in the sample file resource library, and jumping to B6, otherwise, judging that the project sample files do not exist in the sample file resource library, and jumping to B4;
b4, auditing the project template file; jumping to B5 if the audit is passed, otherwise, jumping to B6;
b5, adding the approved project template information into an enterprise template resource library;
and B6, ending.
Extracting project sharing parameters of the archived BIM model:
the method comprises the steps of obtaining a project sharing parameter file of an archived BIM model, naming the project sharing parameter file according to a standard naming mode, comparing the name of the project sharing parameter file with a project sharing parameter file in an established project sharing parameter file resource library, automatically initiating a warehousing auditing process of the project sharing parameter file in the current BIM model if the project sharing parameter file of the BIM model does not exist in the project sharing parameter file resource library, and entering an enterprise project sharing parameter file resource library after being audited by resource managers.
The project sharing parameter is defined in the model project and can be transmitted between different functions of software and between projects, and the project sharing parameter file is in txt format and is a specific carrier of the sharing parameter file.
(1) The project sharing parameter file extraction naming rule is as follows:
1) for the project sharing parameter file extracted from the filed BIM model, carrying out standardized naming on the sharing parameter file, and carrying out file name comparison with an enterprise sharing parameter file database in a resource library so as to judge whether the project sharing parameter file exists in the resource library;
2) entering a digital design resource examination process for project sharing parameter files in an enterprise sharing parameter file database which does not exist in a resource library, and warehousing after the examination is passed;
3) naming the project sharing parameter file extracted from the project by adding a project design number on the basis of the original naming rule for distinguishing, and the specific mode is as follows:
design number _ professional sign _ [ XX ] professional project shared file parameter + R + version number _ XN + release year + version
The extracted building professional project sharing parameter file as from the archive BIM model is named:

Example 2
The invention also discloses an automatic refining system of the BIM model design resources, which comprises the following steps:
as shown in fig. 4, the component extraction module: acquiring all example components in the filed BIM according to an API (application program interface) open interface of BIM software, acquiring a family through the example components, acquiring a family component file through the family, removing repeated family components according to component names, acquiring names and MD5 codes of the remaining components, forming a first component set by all the remaining components, matching the names and the MD5 codes of the first components in the first component set with the names and the MD5 codes of second components in the established enterprise component resource library to obtain specific components which are specific in the current BIM and do not exist in the enterprise component resource library, automatically initiating a component resource auditing process, and warehousing the specific components which pass the auditing into the enterprise component resource library. The component extraction module is used for enriching a digital design resource library and reducing repeated construction work of resources.
Building blocks are the units that make up the BIM model, are the classes of primitives in a class, and group primitives according to the common, same in use, and similar in graphical representation of parameter (attribute) sets. Some or all of the attributes of different primitives in a building block may have different values, but the settings of the attributes are the same. Due to the characteristics of complex manufacturing, large engineering quantity and the like, the method is a link which occupies a long time in BIM modeling. The system formulated by the invention can automatically identify component resources in the BIM after traversing the BIM of the filed project.
The system extracts the component resource file, and stores the component resource file in an enterprise component resource library after the component resource file is checked. In addition, the quantity and the composition proportion of the three types of component resources in the project file can be checked to assist project managers in checking the use condition of the component resources.
As shown in fig. 5, the template extraction module: extracting project template information (related information such as members, views, drawings and the like) in the archived BIM model to form a project template file, naming the project template file according to a standard naming mode, comparing the name of the project template file with the name of the project template file in an established project template file resource library, uploading the project template file in the current BIM model if the project template file of the BIM model does not exist in the project template file resource library, uploading the project template file to an enterprise project template file resource library after being audited by resource managers, and repeatedly using resources.
The template can set working environments meeting the requirements of different users, including system setting conditions, family setting conditions, project browser setting conditions and the like, and is a very important basic prerequisite link of BIM design. The newly-built BIM project file can be created depending on the existing template, so that various settings and component loading work of the BIM design project in the design process can be greatly reduced, and the completion of the BIM design project is accelerated. The system can extract the sample plate in the filing BIM design project model and initiate the verification process, and the sample plate enters the enterprise sample plate resource library after the verification is finished.
As shown in fig. 6, the project sharing parameter extraction module: the method comprises the steps of obtaining a project sharing parameter file of an archived BIM model, naming the project sharing parameter file of the BIM model according to a standard naming mode, comparing the name of the project sharing parameter file with a sharing parameter file in an established project sharing parameter file resource library, automatically initiating a warehousing audit flow of the project sharing parameter file in the current BIM model if the project sharing parameter file of the BIM model does not exist in the project sharing parameter file resource library, and uploading the project sharing parameter file to an enterprise project sharing parameter file resource library after the audit of resource managers.
General project information is defined in project sharing parameters of the BIM model file, and the project sharing parameters can be transmitted between different projects in a txt document mode. However, due to poor familiarity with BIM software or other reasons, a design BIM model in the form of a txt file does not pass well between different BIM design projects. The system can read the shared parameter txt file in the filed BIM model, store the file in the database, form a transferable file with the project entry as a label, form a parameter file library, provide a shared parameter option for a newly-built BIM design project, simplify BIM design initialization work and improve design efficiency.
The system formulated by the invention can read the BIM design model of the filing region, and extract the internal BIM model design resource after the program operation. FIG. 9 is a flow chart of the use of the system for automatically refining BIM model design resources according to the present invention.
