"Ghost" Alignments

[Alexey.Terno]

Hello,
I have found issue with Alignments. If i copy and paste existing Alignment in C3D I will get additional Alignment with the same name in database without displaying in C3D Prospector Toolspace.

Even after deleting all Alignments from drawing I have still one "ghost" Alignment in database.

Here the code to get all Alignments from database:

[CommandMethod("AlignsList")]
public static void AlignsList()
{
    Document doc = Application.DocumentManager.MdiActiveDocument;
    Database db = doc.Database;
    Editor ed = doc.Editor;
    CivilDocument civildoc = Autodesk.Civil.ApplicationServices.CivilApplication.ActiveDocument;
    List<Alignment> aligns = new List<Alignment>();

    using (Transaction trans = db.TransactionManager.StartTransaction())
    {
        ObjectIdCollection ids = civildoc.GetAlignmentIds();

        foreach (ObjectId id in ids)
        {
            aligns.Add((Alignment)id.GetObject(OpenMode.ForRead));
        }

        ed.WriteMessage("\nTotal Alignments: " + aligns.Count.ToString());
        for (int i = 0; i < aligns.Count; i++)
        {
            ed.WriteMessage("\n     [" + i + "] " + aligns[i].Name);
        }

        trans.Abort();
    }
}

PS. I have using C3D 2016 SP1

When you save, close, reopen the dwg the ghost alignment goes away.
>>>GUESS<<< The ghost alignment may be the one held in memory due to the copy to clipboard.

For this drawing - yes. But I have another drawing from other PC and its have ghost alignments always.

The alignment is likely embedded in a block. Purge all blocks from the drawing and my guess is that the "ghost" alignment will go with them.

Yes - it's works!
Thank you!
