Description
Technical field
The present invention relates to a kind of CAD server unit and method, belong to computer-aided design (CAD) (CAD) field, be specifically related to a kind of Heterogeneous CAD System integrated approach and device.
Background technology
At manufacture, engineering field, there are various computer aided design systems (CAD system) using, often in the different departments of same mechanism, or different designer, due to the consideration of the aspects such as use habit, learning cost, historical resource, need to apply multiple different CAD system simultaneously, design and develop work for identical product or engineering, thereby, making can be integrated between the CAD system of isomery, realizing data interaction, bi-directional drive, collaborative work, is a general demand.
For example, designer A and B design respectively two parts of a bicycle of identical product-----, A uses AutoCAD design vehicle frame, B uses Solidworks design wheel, between the design proposal of A and the design proposal of B, there is multiple dependence, for instance, the designed radius of wheel of B must be less than the half of distance between two wheel shafts of vehicle frame; Therefore, a demand is: B, in the time utilizing Solidworks design wheel, needs the distance of design result---critical data in the Vehicle Frame Design that AutoCAD generates---between two wheel shafts of-vehicle frame of " knowing " A; " knowing " described herein not only relies on the information interchange being conveyed between B such people and people by A to realize, but need certain mechanism, the required key parameter of B in the design proposal of A can in real time, be automatically delivered in the design proposal of B, thereby drive the automatic adjustment of the design proposal of B, otherwise still; , the both sides of dialogue, are not these two designers of A and B yet, but the computer aided design system of A AutoCAD used and B these two isomeries of Solidworks used.
Realize data interaction, bi-directional drive, collaborative work between the CAD system of isomery, current existing technology comprises:
The first, the interoperability of file-level, its target of endeavouring is: a kind of CAD system X institute spanned file, can be converted into can be by the file layout that another kind of CAD system Y identified, and then can in Y, be opened, edit.Application scenarios for above-mentioned example is exactly: first, the design proposal that A is given birth to AutoCAD be converted into a kind of can be by the form that Solidworks identified, B opens the file through format conversion with Solidworks, again with the wheel design file of B oneself, be combined in same assembly, utilize the assembly of Solidworks self to coordinate the function of each part, realize working in coordination with between two design proposals.
The interoperability of file-level, the current solution of industry is Criterion, for example STEP standard (product data model exchange standard), each manufacturer observes jointly, the system of each manufacturer can convert the file of oneself to the intermediate file of standard regulation, also can both read standard compliant intermediate file, by this way, realize the file interoperability of different CAD; The problem that this scheme exists is: file there will be loss of data and mistake in the process of intermediate format conversion, and the design semantic of the non-geometric datas such as parameter, constraint has forfeiture, and the conversion of geometric data is likely failure also; Secondly, due to the broad covered area of standard own, complex structure, and the consideration of each CAD manufacturer based on interests own, each manufacturer is to the support of the standards such as STEP insufficient; Again, the data interaction between the Heterogeneous CAD System realizing in the mode of file-level interoperability is not also accomplished in real time and is automatic.
In prior art, between the second solution Heterogeneous CAD System, the scheme of data interaction problem is interface exploitation, be that the DLL (dynamic link library) that user utilizes each CAD manufacturer to provide is done secondary development, programming realizes the data interaction between Heterogeneous CAD System, in upper example, the DLL (dynamic link library) development sequence that user can provide for AutoCAD, read the distance between two wheel shafts in Vehicle Frame Design scheme, then the DLL (dynamic link library) development sequence providing for Solidworks, the restriction relation in change wheel design scheme.The subject matter of interface exploitation scheme be cost of development compared with high, workload is large, developer must possess program capability, the domestic consumer of non-CAD system can be competent at, and the interface routine of developing is for real needs, be difficult to accomplish general, when the real needs of data interaction change, must rewrite or rewriting program for the demand having changed, the response time of demand is lagged behind; In addition, consider from the angle of required human resources, the technician who simultaneously understands thoroughly CAD system and computer programming has belonged to rare, the personnel that simultaneously understand thoroughly multiple CAD system secondary development are more rare, so, realize the method for data interaction between Heterogeneous CAD System in the mode of interface exploitation, be difficult to be widely used in the applying unit of CAD system.
