由于水利水电工程中利用南方CASS断面法计量有很多不便之处,通过利用VBA编程对南方地形地藉成图软件CASS土方计量功能的二次开发,实现了在CASS地形图上由三角网生成断面数据的功能,并给出实现这些功能的关键程序代码。 Because of the inconvenience caused by the CASS cross-section method in the water conservancy and hydropower project, by using the VBA programming to develop the CASS earthwork measurement function in the southern terrain, Data functions, and gives the key to achieve these functions code.
