In order to see what of records we have in our drawing lets try this code<br />
_<br />
Public Sub ShowBTRs()<br />
Dim myDwg As Document = DocumentManager.MdiActiveDocument<br />
Using myTrans As Transaction = myDwg.TransactionManager.StartTransaction<br />
Dim myBT As BlockTable = _<br />
myDwg.Database.BlockTableId.GetObject(OpenMode.ForRead)<br />
For Each myBtrID As ObjectId In myBT<br />
Dim myBTR As BlockTableRecord = myBtrID.GetObject(OpenMode.ForRead)<br />
MsgBox(myBTR.Name)<br />
Next<br />
End Using<br />
End Sub<br />
For example we will see<br />
