交通道路中线自动生成，采用vb连接cad交互式采集数据-road centerline automatically generated using vb connecting oral interactive data collection

计算道路单交点对称型中线坐标，同时还可以计算平曲线要素、主点桩号等

道路中线、边桩坐标自动计算，只要输入现有数据，即可得到你想要任一点的坐标，方便现场施工测量(The coordinates of the centerline and side piles of the road can be calculated automatically. As long as the input data is available, the coordinates of any point you want are obtained, so that the field
