Research On Parametric Drawing Of Coal Mine Construction Drawing Based On .NET

Coal mine construction drawing is the general of sinking and driving engineering construction drawing and cavern construction drawing of coal mine. At present coal mine construction drawings is mainly based on the artificial drawing on AutoCAD platform, its drawing workload is big, and modification workload is bigger, its quality and schedule directly affect the construction cycle of mine. In order to reduce the workload of design drawing and improve the efficiency of drawing, it is need to study on parametric drawing of coal mine construction drawing. Through the research on drawing process and methods of coal mine construction drawing, it can found that the drawing step is to follow certain rules in the drawing process of coal mine construction drawing, its design is according to the mining engineering design manual and the relevant norms in design specification of mine construction drawing, this have the conditions of procedural drawings of coal mine construction drawings, it can further realize the parameterized drawing of coal mine construction drawing.This topic is based on the.net framework, using Visual Studio2010 as development tool, using VB.NET as the programming language, for the goal of parameterized drawing automatically of coal mine construction drawing doing specific algorithms and programming implementation, developing the parametric drawing automatically system of coal mine construction drawing. This system connects AutoCAD with AutoCAD ActiveX components based on.NET to manipulate and control the AutoCAD, making AutoCAD as drawing platform of the system, realizing the parametric drawing of construction drawing automatically in AutoCAD. As long as the necessary drawing parameter is inputted to the system, system will calculate and draw automatically, and generate the required types of coal mine construction drawing, the intermediate process without user’s interaction, high degree of automation.This article detailedly Introduces the method to realize parametric drawing of coal mine construction drawing from the system analysis, function module design and development framework model design, database design, user’s interface design, the realization of each module function of construction and related code etc. For shaft construction drawing and cavern construction drawing this article puts forward the method of “what you see and what you draw” to input the parameters. With single way slope quadratic rotary uncouple field and double way slope quadratic rotary uncouple field for example to verify the effect of parametric drawing, the results show that after completion of the required input parameter and executing the drawing commands, it can automatically draw the construction drawing of the uncouple field above in a few seconds.
