The invention provides a kind of BIM modeling methods, Fig. 1 is referred to, Fig. 1 is the BIM modeling methods that the present invention is provided
Flow chart.The BIM modeling methods comprise the following steps：
In step s 11, Building Skin is obtained into CATIA platforms.If zero deflection, into next step.Build table
Skin is usually to make three-dimensional epidermis according to by CAD plan and elevation, or the RHINO forms provided by other people
Building Skin.The Building Skin of the RHINO forms provided by other people needs it importeding into after CATIA platforms, then putting down CAD
Face figure, elevation, axle net, which are imported, carries out three-dimensional check, it is ensured that used after epidermis is errorless.After this step, building table need to be detected
There is deviation in skin and live practical structures.If there is deviation, adjustment of modifying is needed, Building Skin is obtained again to CATIA
In platform.
In step s 12, lattice and numbering are carried out to Building Skin.It is logical according to the epidermis of CAD flat facade self manufacture
The lattice of epidermis can be further carried out after crossing Party A and designing institute's accreditation.With reference to CAD flat facade and the lattice size of design
Opinion carries out lattice to epidermis.Ensure that lattice size and lattice border are beneficial to optimization and processed as far as possible.The epidermis point that other people provide
Lattice need to detect that lattice whether there is flaw, such as：Elongated quadrangle lattice exist broken string become 5 while or at 6,；Whether lattice
Repeat etc..Other people provide epidermis frame bar, and such case is typically that epidermis frame bar is attached on epidermis, need to be about to certainly epidermis according to
Lattice wire cutting, should be noted that frame bar whether there is error with epidermis, need adjustment frame bar to be allowed to attach epidermis if existing
After use.Other people, which are provided in epidermis, has that part face is undivided, and the lattice that Party A provides carefully need to be verified, when there is part face
Undivided situation should split face, then name lattice and resequence.After lattice confirms, tackle it and optimize, it is excellent
The opinion that change form should adopt design is carried out.The priority of optimization is：Flat board, single, ruled surface, hyperbolic.Lattice after optimization
The overall appearance of building can not be influenceed.Wherein, when being numbered, numbering domestic demand include project name, floor, plate number and
Plate additional information.
In step s 13, the design rule of section bar mould figure is established.Section bar mould figure be typically designer in manuscript
Finish and used, it is necessary to extract in importing CATIA, need to check whether mould graph line is continuous before importing, if having T1 Repeated Line Tl
Bar.Due to design size in-depth, the section of mould figure may change, and confirm that mould figure changes after should now being linked up with design
Rule, Xin Motu is imported in model and replaces original mould figure.Can be directly in CATIA voluntarily for the mould figure numbered by a small margin
Modification.It is accurate that the reference location point of section bar mould figure need to confirm with design, follow-up as occurred positioning datum change, should in time with design
Synchronous change, it is to avoid Wrong localization occur in other correlated parts.
In step S14, standard component is set up.Setting up standard component includes：Java standard library is classified；Establish the defeated of standard component
Enter condition；Carry out the foundation of java standard library；The standard component established is named.Classification to standard component：It is different for project,
The classification form of standard component is also differed.It should link up, according to different curtain wall forms standard component be entered with design at design initial stage
Row classification, such as cell curtain wall, frame curtain wall etc..The input condition of standard component：Set up in CATIA files one entitled " INPUT "
Geometric figure collection, it would be desirable to the feature such as well-regulated point, line, surface of reference is put into wherein.It is all under the geometric figure collection
Feature is common reference.The foundation of java standard library：By the section bar mould figure of importing, the CATIA commonly used commands such as stretching, cutting are used
Three-dimensional section bar is generated, incised notch, perforate etc. is included.Principal mode material and framework should first be set up when setting up java standard library, adaptor and uniform
Part etc. is added successively, and adhesive tape, screw etc. can not such as be done without specific demand.Standard component principal mode material should check inside after the completion of setting up
Without continuing to deepen after interference, it should be detected again after the completion of the addition such as adaptor, it is ensured that interference is not present in inside.The life of java standard library
Name：Java standard library should give its unique title after the completion of setting up, and the situation that naming rule need to classify according to standard component confirms.Rear
Avoid repeating bulk mistake caused by title during continuous use.
In step S15, test and modification standard component.Standard component should take diverse location to be tested after the completion of setting up, and examine
Survey with the presence or absence of orientation problem and design defect etc..Change after standard component test goes wrong should follow the original for not changing framework
Then, once framework is changed, then the association of whole standard component is just all changed, and error rate is very high.The position of error is judged first,
Then changed after finding its corresponding father and son's level element, accurate decision element.Before modification, a original text of backup is made sure to keep in mind
Part, it is to avoid the mistake that can not be reversed caused by mistake change.Standard component should be surveyed after the completion of setting up in diverse location sampling
Examination, it is especially desirable to verify special extreme position.
In step s 16, according to the overall generation model of standard component.In this step, secondary development program can be used to give birth to
Into model, using CATIA orders generation model or use developing instrument bar generation model.It is higher or demand is carried for demand
The project of machined parameters is taken, model mass generation, the platform of secondary development should be carried out using language secondary development such as C++ or VB
Unification is not required to, as long as feature reaches.For need to only extract the model of simple machined parameters, CATIA knowledge only need to be used
The module of engineering can Mass production model, such as UDF, POWERCOPY.Then data are extracted using SHEETMETAL functions
Out.For the flow of standardization effort, only need the tool bar of configuration feature that the function of Mass production model can be achieved, this
When model data amount should not be excessive
In step S17, corresponding manuscript and in-process inventory are generated according to model.Parameter is added in standard library file
The information of change, such as point, line, surface, data.Pass through the corresponding Automatic generation of information part manuscript of procedure identification.Reference Design
Opinion and design requirement, the dimensioned area of interpolation data information, such as screw number, glass, passes through addition in correspondence part
The calculation formula of parameter can be such that the data of the model of diverse location accurately calculate.After mass generation model, pass through
Program batch extracting generates in-process inventory, and the wherein gauge outfit of in-process inventory can be with customization type.Add and join in standard library file
Number information, equally needs to increase calculation formula, addition lattice dimension information etc. with in-process inventory, then recognizes phase by program development
Parameter is answered to automatically generate component drawings.
In addition, when being modeled, it is likely that occur the situation of drawing change.In general it is divided into following several situations：
Because when the demand of other party causes the drawing to change, change amount is general all than larger.If it find that main frame type
Material or framework etc. change, then resolutely re-establish standard library file, rather than again and again change original standard component.
Because design in-depth causes drawing to change.Drawing amount of change is generally smaller caused by design in-depth, then only need
Change can just be completed by replacing the section of change of location.
Because design defect causes drawing to change.There is the position of design defect need to increase design species, standard library file
It should synchronously increase, the type newly increased can be generated by java standard library file modification, reduce design time.
The invention has the advantages that：
1, at the beginning of design, outward appearance control of the designer to project is to use to carry out reference to Building Skin model, because
This can also ensure that its outward appearance is accurate with the in-depth that designs a model, designed model.Epidermis model is effectively equivalent to a book
Catalogue, and model is the content of this this book, and epidermis model describes the macroscopic view numbering of model, positional information.And this information
There is inner parameter to be contacted in epidermis and model.Therefore when being modified to epidermis, its concrete model is in journey
It can be also updated under sequence driving, and then ensure that the accuracy of project.
2, because there is the contact described by first point in epidermis and model.Therefore, designer can be placed on more energy
