			Autodesk CAD實體集合另存為小工具
		
            
		
            一，使用Autodesk CAD的二次開發(fā)技術ObjectARX（依賴與Autodesk CAD）。其中有c++和C#版，這里使用C#版。
            

            二，生成的dll（C#）或arx（c++），必須被拷貝到ACAD的目錄下，且在ACAD中使用命令netload或appload加載生成的dll或arx，加載后我們在ACAD中輸入我們的命令即可。（下面小程序的命令是SaveDwg）
            

            三，小程序的功能是選取ACAD中打開的dwg圖紙上的一些內容，然后保存為另一張dwg圖紙。
            

            四，c#的代碼如下，比較簡單，只考慮了簡單的情況。
            

            using System;
            using System.Collections.Generic;
            using System.Text;
            using System.Windows.Forms;
            using System.Collections;

            using Autodesk.AutoCAD.Runtime;
            using Autodesk.AutoCAD.DatabaseServices;
            using Autodesk.AutoCAD.EditorInput;
            using Autodesk.AutoCAD.ApplicationServices;

            namespace SaveDwg
            {
                            public class Program
                            {   
             
                    [CommandMethod(            "SaveDwg")]   
                    
                                public void SaveDwg()
                                {
                                    try
                                    {

                            Database db             = HostApplicationServices.WorkingDatabase;

                            SelectionSet selectionset;
                            ArrayList setList             = new ArrayList();

                            Editor ed             = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument.Editor;
                            ed.WriteMessage(            "welcome to use the tool, it can save as a dwg file for your selected entities.\n");
                            PromptSelectionOptions selectionOptions             = new PromptSelectionOptions();
                            PromptSelectionResult selectionResult;
                            selectionResult             = ed.GetSelection(selectionOptions);
                                        if (selectionResult.Status != PromptStatus.OK)
                                        {
                                ed.WriteMessage(            "select error, please use command again.\n");
                                            return;
                            }
                                        else
                                        {
                                selectionset             = selectionResult.Value;
                                            foreach (ObjectId id in selectionset.GetObjectIds())
                                            {
                                    DBObject ob             = id.Open(OpenMode.ForRead);
                                    Entity ent             = ob as Entity;
                                                if (ent != null)
                                                {
                                        Entity ent2             = ent.Clone() as Entity;
                                        setList.Add(ent2);
                                        ed.WriteMessage(            "copying entity is successful.\n");
                                    }                                    
                                    ob.Close();
                                }
                            }
                            ed.WriteMessage(            "select and copy successfully.\n");

                            Database Db             = new Database(true, false);
                            HostApplicationServices.WorkingDatabase             = Db;
                            Autodesk.AutoCAD.DatabaseServices.TransactionManager manager             = Db.TransactionManager;
                                        using (Transaction transaction = manager.StartTransaction())
                                        {
                                BlockTable table             = (BlockTable)manager.GetObject(Db.BlockTableId, OpenMode.ForWrite);
                                BlockTableRecord record             = (BlockTableRecord)manager.GetObject(Db.CurrentSpaceId, OpenMode.ForWrite);

                                            foreach (Object obj in setList)
                                            {
                                    Entity ent             = obj as Entity;
                                                if (ent != null)
                                                {
                                        record.AppendEntity(ent);
                                                    //manager.AddNewlyCreatedDBObject(ent,true);
                                    }

                                }
                                record.Close();
                                table.Close();
                                transaction.Commit();
                            }

                            SaveFileDialog dialog             = new SaveFileDialog();
                                        string filePath;
                                        if (DialogResult.OK == dialog.ShowDialog())
                                        {
                                filePath             = dialog.FileName;
                                Db.SaveAs(filePath, DwgVersion.Current);
                            }
                            
                        }
                                    catch(System.Exception e)
                                    {
                            MessageBox.Show(            "copy fail");
                        }
                    }
                }
            }
            

            五，記得要reference ObjectARX程序需要的dll哦，如下圖：

            六，想要脫離AutodeskCAD處理dwg圖紙，需要使用ObjectDBX技術，最新版改名為realdwg技術。

				夢在天涯？你好，看了你的關于“Autodesk CAD實體集合另存為小工具”文章很興趣，因為我做模具設計，經(jīng)常需要將一個圖中的單個圖拷貝給別人線割，如果有了你的那個savedwg，工作為方便好多，但是我又不會C++，能否將編譯后的arx文件發(fā)給我，另外，如果能給個視頻教程，本人將更感激!謝謝了!我的郵箱是：guoling0412@163.com  回復  更多評論
