如下图所示，获取多个实体的最大包围盒，用红色线表示：

也可单独选圆的包围盒

部分代码如下：

using System.Runtime.CompilerServices;
using Wform = System.Windows.Forms;
using System.IO;
using System.Windows.Forms;
//using Excel = NetOffice.ExcelApi;

namespace AcTools
{

    public class Class1
    {
        #region 
        //Polyline pl = new Polyline(3);
        //pl.AddVertexAt(0, new Point2d(10, 2), 0, 0, 0); // 起点 
        //pl.AddVertexAt(1, new Point2d(30, 5), 0, 0, 0); // 起点 
        //pl.AddVertexAt(2, new Point2d(50, 25), 0, 0, 0); // 起点 
        //Editor ed = Application.DocumentManager.MdiActiveDocument.Editor;
        //db.AddEntityToModeSpace(line);
        #endregion
        [CommandMethod("xx")]
        public void XX()
        {   var db = Z.db;
            /// 包围盒
            List<Entity> ents = db.SelectEntities<Entity>();
            List<double> lis = Getboxs(ents);
            Polyline pl = new
