规则重定义OverRule
注意：该规则重定义不支持Jig绘制直线，只能静态生成，否则会导致CAD崩溃；
AddLine命令就是为了测试OverRule而专门添加的静态画直线方法；

Overrule.Overruling = true;
}
///
/// 结束规则重定义
///
[CommandMethod("EndOverRule")]
public void EndOverRule()
{

{
Random r = new Random();
Database db = HostApplicationServices.WorkingDatabase;
using (Transaction tr =db.TransactionManager.StartTransaction())
{
BlockTable bt = tr.GetObject(db.BlockTableId,OpenMode.ForRead) as BlockTable;
BlockTableRecord btr = tr.GetObject(bt[BlockTableRecord.ModelSpace],OpenMode.ForWrite) as BlockTableRecord;
Line line = new Line(new Point3d(r.Next(0,500), r.Next(0, 200),0), new Point3d(r.Next(0, 500), r.Next(0, 200), 0));
btr.AppendEntity(line);
tr.AddNewlyCreatedDBObject(line ,true);
tr.Commit();
}

菜单层级结构
基础知识：
嵌入 AutoCAD 的窗体有两种:
ModalDialog(模态对话框)， Application.ShowModalDialog(form);
ModelessDialog(非模态对话框) ， Application.ShowModelessDialog(form);
一、模态对话框
ModalDialog(模态对话框)为不可切换焦点的对话框， 模态窗体显示的时候程序的焦点始终保持在模态窗体上；
如果需要切换到 AutoCAD 环境进行交互的时候需要EditorUserInteraction 类来切换焦点到 AutoCAD 的命令行；
如果将焦点从CAD切换回窗口，首先需要结束EditorUserInteraction ，然后再用Focus()方法将焦点重新回到窗体；
二、非模态对话框
ModelessDialog(非模态对话框)为活动焦点的对话框，程序焦点可以自由的从 AutoCAD 界面到窗体之间切换，主要用于
用户与 AutoCAD 环境的即时交互操作。
using (EditorUserInteraction edUsrInt = ed.StartUserInteraction(this))
{
//交互过程
edUsrInt.End(); //交互结束.
this.Focus();
}
交互测试-通过窗口选择点
///
/// 通过交互窗口选择点
///
[CommandMethod("SelectPointDialog")]
public void SelectPointDialog()
{
using (SelectPointForm form=new SelectPointForm())
{
//像CAD提示窗口一样，不在任务栏显示
form.ShowInTaskbar = false;
//将form窗口作为模态窗口进行显示
Application.ShowModalDialog(form);
//将textBox1的文本信息，显示到Editor窗口
Application.DocumentManager.MdiActiveDocument.Editor.WriteMessage(form.textBox1.Text);
}
} ///
/// 将焦点切换至CAD，以便选择点
///
///
///
private void button1_Click(object sender, EventArgs e)
{
Editor ed = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument.Editor;
using (EditorUserInteraction interaction = ed.StartUserInteraction(this))
{
Point3d point = GetPoint3D("\n选择点");
textBox1.Text = $"选择点的坐标 X:{point.X},Y:{point.Y},Z:{point.Z}";
interaction.End();
this.Focus();
}
}
///
/// 提示用户拾取一个点
///
///
///
/// 确认按钮
///
///
///
private void button2_Click(object sender, EventArgs e)
{
this.DialogResult = DialogResult.OK;
this.Close();
}
///
/// 取消按钮
///
///
///
private void button3_Click(object sender, EventArgs e)
{
this.DialogResult = DialogResult.Cancel;
this.Close();
