DeepCloneObjects between two databases

[Anonymous]

The command is 5rep:

docA is the target database, it is where 5rep is entered
docB is the source database, and it's opened by 5rep

5rep is meant to copy objects from docB to docA
It requires a complex selection filter, that's why I need to open docB to get an Editor.

The following simplified code works when deep cloning objects within the same database, i.e docB
It fails when deep cloning objects from docB to docA (see commented portion)

Thanks for any help

DeepClone (and deepCloneObjects) is only for
within the same database.  For cloning between databases, you must use the
wblockClone mechanism (in your case the wblockCloneObjects()
function).

Thank you Art, it works:

{code}
dbB.WblockCloneObjects(
oicB,
msA.Id,
new IdMapping(),
DuplicateRecordCloning.Replace,
false);
{code}

AutoCAD NET C# copy from a drawing to another: use WblockClone

*edit*: the clone objects don't show up immediately in the target drawing window, although they are actually copied. I'm looking into QueueForGraphicsFlush to update the screen, not sure yet if this is the right way to do it.

                String strFolderName = strFileName;
                strFileName = strFileName + ".dwg";
                String strPathName;
                String pathName = Assembly.GetExecutingAssembly().Location;
                pathName = pathName.Replace("LayerFilter.dll", "Drawing");
                DirectoryInfo dirInfo = Directory.CreateDirectory(pathName + "\\" + strFolderName);
                if (System.IO.File.Exists(pathName + "\\" + strFolderName))
                {
                    return;
                }
                dbNew.SaveAs(pathName + "\\" + strFolderName + "\\" + strFileName, DwgVersion.Newest);
                strPathName = pathName + "\\Temp\\" + strFileName;                           
            }

}

here i take the objectid collection as xref filter by its layer name.i tried to clone the object in new dwg its shows eWrongdatabase.

If the document you are deep-cloning the objects into is not the Active document the graphics will not be correctly generated.

You can either make the destination document active, or don't open it in the editor (use Database.ReadDwgFile() to open it).
