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
