Insert block in multiple documents

will.wydock — Sat, 29 Jan 2022 16:57:20 GMT

Hi,

I am trying to create a routine for inserting a block (ie. Record Stamp) into multiple dwg files. I thought I have all the information but I can not get the routine to run. I have tried getting the documents and adding a lock and it still does not seem to make a difference. Is there something that i am missing in my code to do this, or is this even possible?

Thanks in Advance

private static Document _document; private static Editor _commandLine; [CommandMethod("gcs-MultiDocInsertBlock")] public void MultiDocInsertBlock() { _document = CADApplication.DocumentManager.MdiActiveDocument; _commandLine = _document.Editor; BlockFileDialog().ShowDialog(); var blockFileName = BlockFileDialog().FileName; var blockName = Path.GetFileName(blockFileName); if (FileDialog().ShowDialog() != DialogResult.OK) return; var insPt = SetPoint(); foreach (var file in FileDialog().FileNames) { _commandLine.WriteMessage("file is "+ file); try { using (var database = new Database(false, true)) { Document document = CADApplication.DocumentManager.GetDocument(database); using(document.LockDocument()) { database.ReadDwgFile(file, FileOpenMode.OpenForReadAndAllShare, true, null); using (var transaction = database.TransactionManager.StartOpenCloseTransaction()) { var blockTable = (BlockTable)transaction.GetObject(database.BlockTableId, OpenMode.ForRead); if (blockTable.Has(blockName)) { _commandLine.WriteMessage("block does exist!"); return; } _commandLine.WriteMessage("block does not exist!"); using (var sourceDb = new Database(false, true)) { sourceDb.ReadDwgFile(blockFileName, FileOpenMode.OpenForReadAndAllShare, true, ""); database.Insert(blockName, sourceDb, true); } using (var blockReference = new BlockReference(insPt, blockTable[blockName])) { var space = (BlockTableRecord)transaction.GetObject(database.CurrentSpaceId, OpenMode.ForWrite); space.AppendEntity(blockReference); transaction.AddNewlyCreatedDBObject(blockReference, true); } transaction.Commit(); } database.SaveAs(file, DwgVersion.Current); } } } catch (Exception ex) { _commandLine.WriteMessage($"\n{file}: {ex}"); } } } private static Point3d SetPoint() { var promptPointOptions = new PromptPointOptions("") { Message = "\nEnter the start point of the line: " }; var promptPointResult = _commandLine.GetPoint(promptPointOptions); var point3d = promptPointResult.Value; return point3d; } private static OpenFileDialog FileDialog() { var openFileDialog = new OpenFileDialog { InitialDirectory = "c:\\", Filter = @"DWG Files (*.dwg)|*.dwg", FilterIndex = 2, RestoreDirectory = true, Multiselect = true, Title = @"Select CAD files to update" }; return openFileDialog; } private static OpenFileDialog BlockFileDialog() { var openFileDialog = new OpenFileDialog { InitialDirectory = "c:\\", Filter = @"DWG Files (*.dwg)|*.dwg", FilterIndex = 2, RestoreDirectory = true, Multiselect = false, Title = @"Select block file to insert" }; return openFileDialog; }

Hi,

I think the first problem is here:

Document document =  CADApplication.DocumentManager.GetDocument(database);

While using a 'side database' (i.e. new Database & ReadDwgFile) you cannot access to the document of this database (and most of the time you not need to).

The document and document lock was a new add as I could not get it working on just the database. It looks like I went the wrong direction in solving this.

Thank you, I was able to solve my multiple document issue.

When I am running my routine, I am always getting the following errors.

eHadMultipleReaders
at Autodesk.AutoCAD.DatabaseServices.Database.Insert(String blockName, Database dataBase, Boolean preserveSourceDatabase)
at software.Common.BlockInsert.MultiDocInsertBlock() in \\Software\Common\BlockInsert.cs:line 56

from what I have been reading that means that the database has been open and not closed. It does not matter whether I have used an old file or a brand new file that I have created. I am still getting the same error. How do you close a database to make sure that this error doesn't occur?

Thanks,

eHadMultipleReaders is probably due to the using of an OpenCloseTransaction instead of a standard transaction.

This seems to work.

[CommandMethod("TEST")] public static void Test() { var doc = AcAp.DocumentManager.MdiActiveDocument; var ed = doc.Editor; if (blockFileDialog.ShowDialog() != DialogResult.OK) return; if (targetFilesDialog.ShowDialog() != DialogResult.OK) return; var pointResult = ed.GetPoint("\nEnter the start point of the line: "); if (pointResult.Status != PromptStatus.OK) return; string blockName = Path.GetFileNameWithoutExtension(blockFileDialog.FileName); var insPoint = pointResult.Value.TransformBy(ed.CurrentUserCoordinateSystem); using (var sourceDb = new Database(false, true)) { sourceDb.ReadDwgFile(blockFileDialog.FileName, FileOpenMode.OpenForReadAndReadShare, true, null); foreach (string targetFile in targetFilesDialog.FileNames) { using (var targetDb = new Database(false, true)) { targetDb.ReadDwgFile(targetFile, FileOpenMode.OpenForReadAndAllShare, true, null); using (var tr = targetDb.TransactionManager.StartTransaction()) { var blockTable = (BlockTable)tr.GetObject(targetDb.BlockTableId, OpenMode.ForRead); if (!blockTable.Has(blockName)) { var space = (BlockTableRecord)tr.GetObject(targetDb.CurrentSpaceId, OpenMode.ForWrite); var id = targetDb.Insert(blockName, sourceDb, true); var br = new BlockReference(insPoint, id); space.AppendEntity(br); tr.AddNewlyCreatedDBObject(br, true); targetDb.SaveAs(targetFile, DwgVersion.Current); } tr.Commit(); } } } } } private static OpenFileDialog targetFilesDialog = new OpenFileDialog { InitialDirectory = "c:\\", Filter = @"DWG Files (*.dwg)|*.dwg", FilterIndex = 2, RestoreDirectory = true, Multiselect = true, Title = @"Select CAD files to update" }; private static OpenFileDialog blockFileDialog = new OpenFileDialog { InitialDirectory = "c:\\", Filter = @"DWG Files (*.dwg)|*.dwg", FilterIndex = 2, RestoreDirectory = true, Multiselect = false, Title = @"Select block file to insert" };
