Hello Forum,

after I redefine a block (I make it bigger), I can't select the block by clicking on the part that's gotten bigger. It is as if AutoCAD still remembers the outlining of the previous smaller block and if I click outside this outlining it doesnt select the block. If I save, close and reopen the drawing everything is fine and I can select the block as normal.

Why is this caused?

Thank you.

// Insert from dwg file.
using (dbInsert = new Database(false, true))
{
    dbInsert.ReadDwgFile(strDwgPath, System.IO.FileShare.Read, true, "");
    oidInsert = dbActive.Insert(System.IO.Path.GetFileNameWithoutExtension(strDwgPath), dbInsert, true);
}

// Regenerate the drawing
CADS.Application.DocumentManager.MdiActiveDocument.Editor.Regen();

... insert random untested code here ....

Dim doc As Document = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument

Dim ed As Editor = doc.Editor
Dim db As Database = doc.Database 

Using tr As Transaction = db.TransactionManager.StartTransaction()

Dim bref As BlockReference = Nothing

.. do stuff

bref.RecordGraphicsModified(True)
tr.TransactionManager.QueueForGraphicsFlush()
doc.TransactionManager.FlushGraphics()
ed.UpdateScreen()
tr.Commit()
