Study And Development On Retaining Wall Drawing System Based On ObjectARX

With the development of the western economy in China, the construction for parts of the infrastructure prevails now and the construction of the highway reachs a new peak.For the highway design engineers, the the current design task is very heavy and the amount of drawing working is large, so they are in dire need of the system software of CAD which can raise the efficiency of design significantly. In highway design task, as the basic structure of the highway road to block the soil, the retaining wall takes on the very fresh and clear characteristics such as low technique contents, simple and mechanical drawing skills and large drawing workload. These peculiarities force the engineers to spend most time in doing the simple and mechanical drawing job and can't be free from this all day. They have no time to concentrate on studing the optimization of the highway path line scheme. Therefore, the designers need urgently a and drawing software for retaining wall design which can be learned easily, purchased at low price and retrench manpower. According to these facts, this thesis aimes at this kind of requirement of the highway construction, carries on the detailed research to the retaining wall drawing system, and make use of the VC++ 6.0 and ObjectARX 2000 SDK, based the Accees database, developes the retaining wall drawing system based on ARX(AutoCAD Runtime eXtension) ( DTQ2005) in AutoCAD 2000/2002 environments. First this text carried on the requirements analysis of the software system in the introduction, carried on the study to the origins,developing condition and for grounds of the highway and the Retaining Wall CAD, enucleated the research background and meanings of this topic; Second this text carried on the detailed analysis to the selection, characteristics and function of the develop tool and it analysed the basic technique of developing the program;Then this text concluded the peculiarities of the retaining wall, abstracting the technique and processes of the software implementation from the manual drawing method of the retaining wall, and it carried on the research to the automatical subsection in the retaining wall CAD system, and gived the arithmetic that solves this problem; Finally this text studied some pivotal techniques of the topic, gived the source code and displayed the implementation frame structure of the retaining wall drawing system and the software processes;At the textual conclusion fraction, did the summary and put forward the topic direction and the important point of the follow-up research to the textual research work. The contents of this topic research to the retaining wall design and drawing of the highway is operable. Bing opposite to the traditional drawing method, it can raise the labor efficiency consumedly.Because the function and cheap price of this software system, it has the very strong come-on towing force for the design unit and individual, also has the really fine market place foreground and the developping potential.In addition, pass the research of this topic, the writer still craves that it has the meaning of elicitation and referrence towards the CAD development that other of the same kind patterns of building, achieving to the purpose that throwing out a brick to attract a jade.
