Specific implementation mode
In the following, being described in further detail to the implementation of technical solution in conjunction with attached drawing.
It will be appreciated by those of skill in the art that although the following description is related to many of embodiment for the present invention
Technical detail, but be only for not meaning that any restrictions for illustrating the example of the principle of the present invention.The present invention can be applicable in
In different from the occasion except technical detail exemplified below, without departing from the principle and spirit of the invention.
It, may pair can be in description in the present specification in addition, tedious in order to avoid making the description of this specification be limited to
The portion of techniques details obtained in prior art data has carried out the processing such as omission, simplification, accommodation, this technology for this field
It will be understood by for personnel, and this does not interfere with the open adequacy of this specification.
Hereinafter, it will describe for realizing the embodiment of the present invention.
Fig. 1 is the subway engineering collaborative design split based on DWG file with recombination method according to the embodiment of the present invention
The configuration diagram of system.As shown in Figure 1, splitting the subway engineering collaborative design system packet with recombination method based on DWG file
Include central database, project database, local device (not shown), wherein the local device be used for from a certain engineering item
Pel is split in the relevant design drawing file of mesh, and will upload to the central database with the relevant primitive data of pel,
The project database is for storing and the relevant design drawing file of engineering project, wherein in the design drawing file,
Each pel has corresponding primitive data, pel basic information and pel fresh information, and the primitive data includes pel
Pictorial information, the pel basic information include primitive handle, pel version, pel mark, and the pel fresh information includes
Pel state.
Fig. 2 is according to the subway station CAD design file declustering of the embodiment of the present invention and the fractionation flow of recombination method
Schematic diagram.
Referring to Fig. 2 come the step of illustrating to split flow.
Step 1 retrieves an entity from the model space of cad file (such as DWG file) by traversal, if traversal
Retrieval is finished less than entity, then method terminates；
Whether the entity that step 2, judgement retrieve in step 1 is novel entities (can be according to pel state)；
Specifically, the mark (UUID) that the entity retrieved in step 1 is searched in entity data bak, if in entity
There are above-mentioned UUID in database, then further retrieve the growth data corresponding to the entity, carry out handle verification (HANDLE
Verification), if the HANDLE values in entity data bak are identical as the HANDLE values in growth data, for old entity.
Wherein, the growth data corresponding to entity includes：UUID, version number, user, profession, HANDLE.
If there is no the growth datas of UUID or the HANDLE values to differ in entity data bak, it is determined as new
Entity.
If step 3 judges that the entity is old entity in step 2, it is updated condition adjudgement,
If state is " newly-built ", the state of the entity in entity data bak is changed,
If state is " update ", increase the version number of the entity；
If step 4, state is " not updating ", step 1 is returned to, traversal mode is continued through and retrieves entity,
The entity is exported to entity data bak from cad file, and returns to step 1 by step 5.
Fig. 3 is according to the subway station CAD design file declustering of the embodiment of the present invention and the recombination flow of recombination method
Schematic diagram.
Referring to Fig. 3 come the step of illustrating recombined streams journey.
Step 1, from entity data bak take out recombination drawing need total data (including solid data, growth data,
Symbol table, dictionary etc.), solid data is pressed into entity array；
Step 2, traversal searches the entity with UUID associated with recombination drawing in entity array, if traversed
Complete retrieval terminates less than entity, then method；
Whether step 3, judgement have created the entity in drawing；
Specifically, the m_idObject for obtaining entity illustrates not yet to create the entity if m_idObject is NULL；
If step 4 not yet creates the entity, locking data structure imports the entity in drawing, and returns to step
Rapid 2；
As special circumstances, if finding that when importing the entity, the entity has block's attribute, it is returned only to and creates
Entity pointer, rather than directly create entity.
Step 5 creates symbol table in drawing, and unlocks data structure.
