Specific implementation mode
In order to enable those skilled in the art to better understand the solution of the present invention, with reference to the accompanying drawings and detailed description
The present invention is described in further detail.Obviously, described embodiments are only a part of the embodiments of the present invention, rather than
Whole embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Lower obtained every other embodiment, shall fall within the protection scope of the present invention.
A kind of stream of specific implementation mode of three-dimensional building model method for dividing and processing provided by the present invention based on BIM
Journey figure is as shown in Figure 1, this method includes：
Step S101：Obtain the three-dimensional building model generated based on BIM；
BIM three-dimensional buildings model is that the three-dimensional that designer is designed based on BIM design platforms is built in the embodiment of the present invention
Build figure.
Step S102：The three-dimensional building model is projected, two-dimensional model is generated, each component is generated and corresponds to
Area grid figure layer；
Component is can specifically to be divided the division of preset building unit in assembled architecture according to actual conditions,
Such as one block of wallboard, beam or column.Design department carries out architectural design according to selected architectural structure system, including house type, appearance,
Hot-water heating Electromechanical Design etc., but factory cannot whole house disposable production, it is necessary to the production of one component of a component, example
Such as, a face wall in a house, several meters to tens meters long to differ, factory can not possibly disposably produce super big wallboard again, transport
Defeated and lifting is too difficult, and too small wallboard manufacture and efficiency of assembling are again too low, and assembly also bothers, and need to do the splicing node of water-proofing treatment
Too much, it is the extremely crucial of contact design, manufacture and assembly so how building splits into reasonable, suitable prefabricated components
A ring, be known as tearing plate open in industry, tear that plate is more reasonable, and manufacture is simpler, and production efficiency is also higher open, assembly is simple, efficiency of assembling
Also higher.
By being projected to three-dimensional building model in this step, directly three-dimensional building model conversion can be built for two dimension
Build model.Meanwhile when three-dimensional building model generates two-dimentional buildings model, generating the area grid figure layer of each component.
The three-dimensional building model method for dividing and processing based on BIM that the embodiment of the present invention is provided, described to described three
Dimension buildings model is projected, and two-dimensional model is generated, and is generated the corresponding area grid figure layer of each component and is further included later：

System.By assigning area grid layer properties, can make also to include its component category in the corresponding two dimensional model of each single component
Property information, the use of more convenient user.
Step S103：The area grid figure layer is obtained, is torn open the two-dimensional model using the method that geometry surrounds
It is divided into the corresponding two dimensional model of each single component, generates and split file.
Area grid figure layer is obtained, the region of a certain component is searched, using the method that geometry surrounds by the component from two dimension
Complete single figure is captured out in areal model, as fractionation file.
In addition, the two-dimensional model is split as each list by the embodiment of the present invention in the method surrounded using geometry
The corresponding two dimensional model of a component, generates after splitting file and further includes：It is described in generation with the version of component, coding information
File is split to be named.
Specifically, the version of component is the update to version in design process, and coding information is each in BIM models
Unique identification code that component assigns.The form of expression of unique identification code can be number.In BIM design processes,
To assembled, each component assigns a unique number attribute (can automatically generate), in design, manufacture, transport and object
Stream is all made of this number and is managed.Correlated process information is collected with this unique number：Including stock, material,
Tooling, processing teams and groups personnel, assembly teams and groups, assembly time etc..
As a kind of specific implementation mode, in the embodiment of the present invention identification code of component can specifically by project, Lou Dong,
The information such as floor, component, product information are constituted.Under normal circumstances, project and Lou Dongjun have had unique code, herein can be straight
Connect calling.Floor, element type can be according to serial number gencrations, such as floor 01, element type 02, then the coding generated can be with
It is 0102.Further, it is also conceivable to product coding, the common mode component in same project, same type are assigned in coding
Give identical product coding.It is combined by product code and other unique encodings, generates the unique encodings of PC components.Each information
Sequence between serial number can be carried out according to set sequence, can also be voluntarily arranged by user, this does not influence the reality of the present invention
It is existing.For example, the sequence that project-Lou Dong-floor-element type-product coding may be used is arranged, generate finally only
One identification code.
After generating fractionation file, version, the coding information of component is used to be named for the fractionation file generated.
