动态,交互道路CAD平面设计系统研究

针对当前国内公路平面设计程序交互性差或无交互的现状，以我国习用的公路平面设计方法及过程为基本思路，吸取国外设计方法的精华，提出动态、交互公路平面设计方法．该方法在公路平面设计中，既保留习用的导线设计方法，又能通过任意拖动导线交点及平曲线半径任意组合线形，在平面设计中显示其设计的灵活性．

Study on Dynamic and Interactive CAD in Highway Horizontal Alignment Design

In the light of the software for highway horizontal alignment absent of interaction or non interaction, this paper presents a dynamic interactive method, which is based on the traditional method and process and takes the essence of abroad design method. This new method not only remains the advantages of the traditional traverse method, but also creates greater flexibility on design of curve combination by dragging traverse intersections and radius of alignment. Therefore, it provides much convenience for highway horizontal alignment design.
