能在MDT5/6环境下对已经存在地曲面进行全部和局部区域展开，同时能进行源曲面和展开平面上点和线地相互映射-in MDT5 / 6 right environment to surface already exists for all regional and local begin and can be the source for surface and start Plane dots and lines to the mutual mapping

读取数据，并由此生成一系列数据点，有这些数据点生成曲面，满足用户需求-Read the data, and thus generate a series of data points, these data points generated surface, to meet customer needs
