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 flow chart of specific implementation mode of the method for X-Y scheme automatic marking provided by the present invention based on BIM
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, 2 d plane picture is generated；
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.
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.
Optionally, the area of each component can be generated when three-dimensional building model generates two-dimentional buildings model in this step
Domain grid figure layer.The attribute information for obtaining each component, establish the corresponding area grid figure layer of component and the attribute information it
Between correspondence.The area grid figure layer is obtained, is split as the two-dimensional model using the method that geometry surrounds
The corresponding two dimensional model of each single component, generates and splits file.
Step S103：According to default mark rule, size marking is carried out to the 2 d plane picture, is generated with mark letter
The 2 d plane picture of breath.
Presetting mark rule includes：Scale setting position, calibration coordinate information, mark font size, mark
Sequentially, the arranged distribution marked.For example, mark cannot intersect between marking line；Specific region cannot mark, markup information
It is short as far as possible with raw information, the specific rules such as mark as far as possible alignment.
The method of X-Y scheme automatic marking provided by the present invention based on BIM, by obtaining the three-dimensional generated based on BIM
Buildings model；Three-dimensional building model is projected, 2 d plane picture is generated；According to default mark rule, to 2 d plane picture
Size marking is carried out, the 2 d plane picture with markup information is generated.X-Y scheme provided by the present invention based on BIM is marked automatically
The method of note carries out two-dimentional conversion based on BIM platforms to three-dimensional building model, and graphics is automatically generated as 2 d plane picture,
And size marking is carried out to the 2 d plane picture automatically, so that subsequent production processing link uses, improve BIM assembled architectures
The efficiency of technology.
It is regular according to default mark in embodiment provided by the present invention with reference to Fig. 2 as a kind of specific implementation mode,
Size marking is carried out to the 2 d plane picture, generating the process of the 2 d plane picture with markup information can specifically include：
Step S201：Receive the instruction that user selects component to be marked；
Step S202：Receive the instruction of user's selection mark rule from preset mark template；
Step S203：Selected mark rule is called, the component to be marked is labeled；
Step S204：Whole components in the 2 d plane picture are labeled according to preset order, are generated with mark
Note the 2 d plane picture of information.
The corresponding mark template of different component can be pre-set in the embodiment of the present invention, and 3-5 kind marks can be specifically set
Injection molded plate, for selection by the user.The type of structure is may particularly include with its corresponding notation methods in each mark template.Example
Such as, for wallboard, how length and width dimensions mark, the sequence of the spacing distance between dimension line and component, mark, mark font
Size etc..
User can select one of them as the specific structure after having selected some specific component in marking template
The corresponding labelling schemes of part are automatically labeled the specific component.
Mark rule can specifically include：The position of scale setting, the coordinate information of calibration, the size for marking font, mark
The sequence of note, the arranged distribution of mark.
The embodiment of the present invention quickly can carry out size by pre-setting the corresponding mark template of each component to component
Mark, it is user-friendly.
As another specific implementation mode, with reference to Fig. 3, advised according to default mark in embodiment provided by the present invention
Then, size marking is carried out to the 2 d plane picture, generating the process of the 2 d plane picture with markup information can specifically wrap
It includes：
Step S301：According to pre-set constraint rule, mark is calculated using the Nonlinear Programming Algorithm of optimization
Data；
Step S302：Whole components in the 2 d plane picture are labeled according to the labeled data, generate band
There is the 2 d plane picture of markup information.
The embodiment of the present invention can be according to the relationship between the mask method of 2 d plane picture, marking line and marking line, mark
Alignment rule is noted, 2 d plane picture is labeled and is shown with the Nonlinear Programming Algorithm determination based on constraint, in target
It is shown within the scope of penalties.
Constraint rule can specifically include：Mark cannot intersect between marking line；Specific region cannot mark, and mark
Information is short as far as possible with raw information, and mark is aligned as far as possible.
The embodiment of the present invention optimizes calculating using nonlinear optimization algorithm, quickly one-touch can carry out ruler to component
Very little mark while user-friendly, can also meet the individual demand of user.
