利用arcgis engine的scene进行三维地形的显示，并进行剖面线绘制、三维叠加，符号标注-Use arcgis engine of three-dimensional terrain display scene, and cross-sectional line drawing, three-dimensional stack, symbol label

用ARCGIS engine进行CAD矢量数据转换为SHP数据，并且通过等高线数据建立三维TIN(可以检查等高线的错误)-CAD vector data conversion performed by ARCGIS engine for the SHP data, and create three-dimensional contour data by TIN (you can check the contours of error)

C#和ARCGIS engine编程，先根据点值生成栅格数据，可以输出为JPG\BMP等格式，然后进行渲染、分层着色，生成等值线，根据等值线实现任意点的插值查询-C# and ARCGIS engine programming, the first based on the point value generating raster data can be exported as JPG \ BMP format, and then rendered, layered coloring, gen
