计算2点之间的距离:访问ObjectARX.NET封装类

在vs2005当中新建个项目CsMgdAcad5，打开Commands.cs代码，添加引用3个空间

view plaincopy to clipboardprint?
using Autodesk.AutoCAD.Runtime;
using Autodesk.AutoCAD.ApplicationServices;
using Autodesk.AutoCAD.EditorInput;
using Autodesk.AutoCAD.Runtime;
using Autodesk.AutoCAD.ApplicationServices;
using Autodesk.AutoCAD.EditorInput;

接着插入语句：[assembly: CommandClass(typeof(CsMgdAcad5.Commands))]，同时注册CsMgdAcad5的命令。

整体的代码如下：

进行编译，在auto cad当中输入netload，加载CsMgdAcad5.dll，然后在输入：AsdkCmd1命令，表示查询CAD某点的坐标。

输入getinstance，表示查询某2点的距离。
