Hi there,
for an automatic proccessing of over 6.000(!) DWGs all drawings need to get ripped off their XRefs.
I tried the following, using the Database.DetachXRef method:
(-------- Code starts --------)
public void DetachXrefs()
{
FolderBrowserDialog fldFolder = new FolderBrowserDialog();
if (fldFolder.ShowDialog() == DialogResult.OK)
{
string[] DWGs = Directory.GetFiles(fldFolder.SelectedPath, "*.dwg");
DocumentCollection dcDocMan = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager;
for (int i = 0; i < DWGs.Length; i++)
{
Document actDWG = dcDocMan.Open(DWGs[\i]);
Database docDB = actDWG.Database;
using (Transaction trDWG = docDB.TransactionManager.StartTransaction())
{
XrefGraph dbXRGraph = docDB.GetHostDwgXrefGraph(true);
for (int j = 0; j < dbXRGraph.NumNodes; j++)
{
try
{
XrefGraphNode xnGraphNode = dbXRGraph.GetXrefNode(i);
DetachChildren(docDB, trDWG, xnGraphNode.BlockTableRecordId);
}
catch //(System.Exception ex)
{
//MessageBox.Show(ex.Message);
}
}
trDWG.Commit();
}
docDB.SaveAs(DWGs[\i], DwgVersion.AC1015);
actDWG.CloseAndDiscard();
}
}
}
private void DetachChildren(Database DB, Transaction trDWG, ObjectId xnGraphId)
{
BlockTableRecord btr = (BlockTableRecord)trDWG.GetObject(xnGraphId, OpenMode.ForRead);
BlockTableRecordEnumerator itIterator = btr.GetEnumerator();
while (itIterator.MoveNext())
{
BlockReference brXRefBlock = (BlockReference)itIterator.Current.GetObject(OpenMode.ForRead);
BlockTableRecord nBTR = (BlockTableRecord)trDWG.GetObject(brXRefBlock.BlockTableRecord, OpenMode.ForRead);
if (nBTR.IsFromExternalReference)
{
DB.DetachXref(nBTR.ObjectId);
}
}
}
(-------- Code ends --------)
But
"BlockTableRecord btr = (BlockTableRecord)trDWG.GetObject(xnGraphId, OpenMode.ForRead);" in DetachChildren
returns an "eInvalidObjectId", the ObjectId is =0. Although the drawing definitly contains (ghosted) XRefs, I can see them in XRef manager.
What's wrong?
Any other suggestion about stripping XRefs?
Thx
Ontario
