找到方法了！
使用WblockCloneObjects
注意红色的部分，不过不知道能不能复制块参照，并且把块参照的引用块定义也一起复制过去，com里的copyobjects方法可是可以做到这一点的，我试验过。
using Autodesk.AutoCAD.Runtime;using Autodesk.AutoCAD.ApplicationServices;using Autodesk.AutoCAD.DatabaseServices;using Autodesk.AutoCAD.Geometry;
[CommandMethod("CopyObjectsBetweenDatabases", CommandFlags.Session)]public static void CopyObjectsBetweenDatabases(){ ObjectIdCollection acObjIdColl = new ObjectIdCollection();
// Get the current document and database Document acDoc = Application.DocumentManager.MdiActiveDocument; Database acCurDb = acDoc.Database;
// Lock the current document using (DocumentLock acLckDocCur = acDoc.LockDocument()) { // Start a transaction using (Transaction acTrans = acCurDb.TransactionManager.StartTransaction()) { // Open the Block table record for read BlockTable acBlkTbl; acBlkTbl = acTrans.GetObject(acCurDb.BlockTableId, OpenMode.ForRead) as BlockTable;
// Open the Block table record Model space for write BlockTableRecord acBlkTblRec; acBlkTblRec = acTrans.GetObject(acBlkTbl[BlockTableRecord.ModelSpace], OpenMode.ForWrite) as BlockTableRecord;
// Create a circle that is at (0,0,0) with a radius of 5 Circle acCirc1 = new Circle(); acCirc1.SetDatabaseDefaults(); acCirc1.Center = new Point3d(0, 0, 0); acCirc1.Radius = 5;
// Add the new object to the block table record and the transaction acBlkTblRec.AppendEntity(acCirc1); acTrans.AddNewlyCreatedDBObject(acCirc1, true);
// Create a circle that is at (0,0,0) with a radius of 7 Circle acCirc2 = new Circle(); acCirc2.SetDatabaseDefaults(); acCirc2.Center = new Point3d(0, 0, 0); acCirc2.Radius = 7;
// Add the new object to the block table record and the transaction acBlkTblRec.AppendEntity(acCirc2); acTrans.AddNewlyCreatedDBObject(acCirc2, true);
// Add all the objects to copy to the new document acObjIdColl = new ObjectIdCollection(); acObjIdColl.Add(acCirc1.ObjectId); acObjIdColl.Add(acCirc2.ObjectId);
// Save the new objects to the database acTrans.Commit(); }
// Unlock the document }
// Change the file and path to match a drawing template on your workstation string sLocalRoot = Application.GetSystemVariable("LOCALROOTPREFIX") as string; string sTemplatePath = sLocalRoot + "Template\\acad.dwt";
// Create a new drawing to copy the objects to DocumentCollection acDocMgr = Application.DocumentManager; Document acNewDoc = acDocMgr.Add(sTemplatePath); Database acDbNewDoc = acNewDoc.Database;
// Lock the new document using (DocumentLock acLckDoc = acNewDoc.LockDocument()) { // Start a transaction in the new database using (Transaction acTrans = acDbNewDoc.TransactionManager.StartTransaction()) { // Open the Block table for read BlockTable acBlkTblNewDoc; acBlkTblNewDoc = acTrans.GetObject(acDbNewDoc.BlockTableId, OpenMode.ForRead) as BlockTable;
// Open the Block table record Model space for read BlockTableRecord acBlkTblRecNewDoc; acBlkTblRecNewDoc = acTrans.GetObject(acBlkTblNewDoc[BlockTableRecord.ModelSpace], OpenMode.ForRead) as BlockTableRecord;
// Clone the objects to the new database IdMapping acIdMap = new IdMapping(); acCurDb.WblockCloneObjects(acObjIdColl, acBlkTblRecNewDoc.ObjectId, acIdMap, DuplicateRecordCloning.Ignore, false);
// Save the copied objects to the database acTrans.Commit(); }
// Unlock the document }
// Set the new document current acDocMgr.MdiActiveDocument = acNewDoc;} |
