namespace CadInsert
{
    public class CadInsert
    {
        [CommandMethod("InsertCad")]
        public void InsertCad()
        {
            //设置CAD文件路径和图框坐标
            string cadFilePath = @"E:\data\cad\demo.DWG";
            Dictionary<string, Point3d> frameCoordinates = new Dictionary<string, Point3d>();
            frameCoordinates.Add("Frame1", new Point3d(0, 0, 0));
            frameCoordinates.Add("Frame2", new Point3d(100, 100, 0));

            //加载CAD插件
            try
            {
                if (!ReferenceEquals(Application.GetSystemVariable("DWGNAME"), null))
                {
                    Document doc = Application.DocumentManager.MdiActiveDocument;
                    Editor ed = doc.Editor;
                    Database db = doc.Database;

                    //打开CAD文件
                    using (Transaction tr = db.TransactionManager.StartTransaction())
                    {

                        BlockTableRecord btr = (BlockTableRecord)tr.GetObject(bt[BlockTableRecord.ModelSpace], OpenMode.ForWrite);

                        //插入图框
                        foreach (KeyValuePair<string, Point3d> kvp in frameCoordinates)
                        {

                            btr.AppendEntity(br);
                            tr.AddNewlyCreatedDBObject(br, true);
                        }

                        tr.Commit();
                    }
                }
            }
            catch (System.Exception ex)
            {
                Console.WriteLine(ex.Message);
            }
        }
    }
