CAD插件程序 开发

凡是根据参数生成固定图形的，CAD插件程序都可以胜任。

效果展示：

1，命令行：

2，右键菜单：

3，工具条，CAD内嵌界面，和winform一样简单

闲话少说，直接上原理和代码：

项目效果查看：
a:在CAD2006的命令行输入netload，加载Test.dll
b1:在命令行输入helloworld可以看到命令功能
b2:右键可以看到右键菜单，画一个红色的圆
b3:左边工具面板多了一个工具条，有个界面可以输入各种参数来画一个组合图形
 
 
1，建一个xindows窗体程序项目，设置输出为类库
2，引用acdbmgd.dll和acmgd.dll
3，引用如下命名空间
using Autodesk.AutoCAD.EditorInput;
using Autodesk.AutoCAD.ApplicationServices;
using Autodesk.AutoCAD.Runtime;
using Autodesk.AutoCAD.DatabaseServices;
using Autodesk.AutoCAD.Geometry;
using Autodesk.AutoCAD.Windows.ToolPalette;
using Autodesk.AutoCAD.Windows;
 
 
4，在Form1上规划界面和后台代码。重点看代码如何实现
 
5，计划是CAD上增加一个面板按钮，点击按钮就打开Form1来自动画图。
这里我们加一个用户控件，拖一个按钮，按钮方法写：
Form1 modalForm = new Form1();
Autodesk.AutoCAD.ApplicationServices.Application.ShowModalDialog(modalForm);
注意这里仅仅是打开的窗体的方式选择了AutoCAD的方式。
想建立一整套工具栏，就多拉几个按钮。按4的方法写好每个按钮执行的代码（可以要个Form1这样的界面，也可以不要，自由选择）
 
6,把这个项目导出还需要一个类来辅助
先看初始化Initialize()和Terminate()方法。这里给CAD加了一个面板工具栏和右键菜单，以及一些命令行

　　

1，这个class1类分别演示了命令行、右键菜单、工具条的实现。注释得非常清楚了，就不做多解释。

                ed.WriteMessage("创建面板集错误");
            }

}

　　

2，CAD展现工具条，添加一个用户控件，取名为ModelessForm。两行代码显示Form1窗体而已。

        {
            Form1 modalForm = new Form1();
            Autodesk.AutoCAD.ApplicationServices.Application.ShowModalDialog(modalForm);
        }
    }
}

　　3，Form1窗体的功能，是根据长宽画一个矩形，矩形的四个角分别画一个圆。因为在CAD里运行，所以使用的类库和正常C#的不同。这里是实现的重点，根据需要写自己的代码。class1类是一个框架，基本不用改。

整个工程打包上来，有兴趣的朋友跑起来玩玩。很少写博客，

 CAD插件技术真心不难，无非是画点线条，CAD内部能实现的，C#调用acdbmgd.dll和acmgd.dll也能实现。
