Intersection Based On Objectarx The For Autocad Technology, Computer-aided Design System

The intersection design is very important.But in the vertical design, the designer couldn't use the form of contour lines to express accurately his design intension.He could only write few elevations of the pavement board corners because of the complexity in design progress and the bother in calculation. The design achievements has little effect to guide and discipline the construction.After studying the reasonable division of the labor between person,drawing flatbed and application program,the author developed "The Intersection Application System" with the using of Visual C++,AutoCAD and ObjectARX, which is also based on the traditional theory of the vertical intersection design. The system can achieve contour lines and elevations of the pavement board corners with the establishing of FACE models seriesly or one by one based on dynamic mutual techmology.The application system also has some small drawing and editting tools for the plane intersection design.
