| As large-scaled hydro curved structures, double-curved arch dams maintain the characteristics of various dam curves, large scale, high cost and long construction cycle. Designing, calculating, drafting and constructing related to them are rather complicated. As a result, no one can construct such a structure successfully just through simple sample amplifying or designing and calculating. As one of the most important steps in designing and constructing an arch dam, arch dam construction layout and graphics processing are crucial to the project quality and construction process. Any mistake or error in any of the procedures will be likely to cause great loss. In light of the complexity of designing and constructing technology, computer-aided design is more and more widely used in designing arch dam, and the requirements are also improved constantly. So such software as those which have friendly interactive user interface, efficient data management and highly software integration are the most important research projects in current arch dam designing and analyzing software development.Based on the idea of visualization and parameterization, the requirements of arch dam design regulations and practical needs, the project aims to develop 3D visual arch dam designing and drawing software system through integrating Object-oriented Programming Techniques (OOPT), Visual Interface Design Techniques(VIDT) and Graphics Processing Techniques(GPT). Adopting VB.NET, the developing techniques and tools of Auto CAD, OOPT and DAO Database Developing Technique, we have developed the basic Auto CAD drawing modules. The designing and drawing platform of this software system is Auto CAD Civil 3D, and its development environment is Visua1 Studio.NET 2005 integrated with VBA. Its convenience, friendly interface and reliable operation have helped this software to play a key role in design and production... |
