Invisible entity in BlockReference

Anonymous — Tue, 06 Oct 2009 10:20:43 GMT

I'm triing to add entities to BlockReference. Entities, that I want to add is not in database (created before in code).

{code}
public static void AddEntityToBR(BlockReference br_Inc, Entity[] are_Inc)
{
Database db = HostApplicationServices.WorkingDatabase;
Autodesk.AutoCAD.DatabaseServices.TransactionManager tm = db.TransactionManager;
Autodesk.AutoCAD.ApplicationServices.Document dCurrentDock = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument;

ObjectIdCollection oidcAddedEntities = new ObjectIdCollection();

using (Autodesk.AutoCAD.ApplicationServices.DocumentLock DocLock =
dCurrentDock.LockDocument(Autodesk.AutoCAD.ApplicationServices.DocumentLockMode.Write, null, null, true))
{
using (Transaction trans = tm.StartTransaction())
{
try
{
BlockTable bt = (BlockTable)trans.GetObject(dCurrentDock.Database.BlockTableId, OpenMode.ForWrite, true, true);
BlockTableRecord btr = (BlockTableRecord)trans.GetObject(bt[BlockTableRecord.ModelSpace], OpenMode.ForWrite);

//Add entities to drawing
foreach (Entity eTmp in are_Inc)
{
oidcAddedEntities.Add(btr.AppendEntity(eTmp));
trans.AddNewlyCreatedDBObject(eTmp, true);
}

//Open BlockTableRecord and all entities forwrite as Tony Tanzillo said here http://discussion.autodesk.com/forums/thread.jspa?messageID=5700703�

BlockTableRecord btrOfBR = (BlockTableRecord)trans.GetObject(br_Inc.BlockTableRecord, OpenMode.ForWrite);
foreach (ObjectId oidCur in oidcAddedEntities)
{
DBObject dboTmp = trans.GetObject(oidCur, OpenMode.ForWrite);
}
btrOfBR.AssumeOwnershipOf(oidcAddedEntities);

trans.Commit();
}
catch (Exception)
{
trans.Abort();
throw;
}
}
}
}
{code}
The code above adds entities to BR (BlockReference), but I don't see them on screen (in the drawing). If I doubleclick on BR in AutoCad (I mean open BlockReference editing mode) and then close BlockReference editing mode with save changes, I can see it in the drawing.
I don't know how to make added entities to be visible in the drawing using C#?
If I call this function
{code}
public static void RegenerateWindow()
{
Autodesk.AutoCAD.ApplicationServices.Document doc = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument;

object oAcadDoc = doc.AcadDocument;
oAcadDoc.GetType().InvokeMember("Regen", System.Reflection.BindingFlags.InvokeMethod, null, oAcadDoc,
new object[] { 1 });
}
{code}
added object become visible, but not as member of BR. I mean if i position my cursor on any entity, that belong to BR, whole BR become highlighted. If I position cursor on just added entity, BR do not become highlighted.

Sorry, the discussion software reformatted your code, and I don't have the
time to format it to be readable.

Sorry, what you're trying to do makes no sense.

You're adding new objects to the database, and then
using AssumeOwnershipOf() to transfer them to another
owner block. There is no point in doing that.

Just add the new entities to the block that you want
to be the owner.

Lastly, It's difficult to read code that has identifiers
that are prequalified with the namespace.

I think, that code below is what you advise me to do.

Database db = HostApplicationServices.WorkingDatabase;
TransactionManager tm = db.TransactionManager;
Document dCurrentDock = Application.DocumentManager.MdiActiveDocument;

ObjectIdCollection oidcAddedEntities = new ObjectIdCollection();

using (DocumentLock DocLock = dCurrentDock.LockDocument(DocumentLockMode.Write, null, null, true))
{
using (Transaction trans = tm.StartTransaction())
{
try
{
BlockTableRecord btrOfBR = (BlockTableRecord)trans.GetObject(br_Inc.BlockTableRecord, OpenMode.ForWrite);
foreach (Entity eTmp in are_Inc)
{
oidcAddedEntities.Add(btrOfBR.AppendEntity(eTmp));
trans.AddNewlyCreatedDBObject(eTmp, true);
}

trans.Commit();
}
catch (Exception)
{
trans.Abort();
throw;
}
}
}
}

But situation didn't changed. Newly added entities is invisible. If only I enter BlockReference edit mode, they become vivsible.

You have to regenerate the block references.

Tony, how to regenerate BlockReference?

Re: Invisible entity in BlockReference

Anonymous — Fri, 09 Oct 2009 18:30:25 GMT

I have founded solution.
To regenerate BlockReference you have to regenerate layer, where BR is placed.
