I'm trying to generate a code in .NET to create a layer filter and associate some layers that a have on current drawing on this layer filter. My problem is to identify the DBDictionary ID for call LayerMananger in current drawing.


That is my code:

[CommandMethod("CREATE_LAYER_FILTERS")]

public void CreateLayerFilters()

{

Document doc = Application.DocumentManager.MdiActiveDocument;

Database db = doc.Database;

Editor ed = doc.Editor;using (Transaction tr = db.TransactionManager.StartTransaction())

{

    // Acessa o Dictionary de Layer Filters

    DBDictionary filterDict = tr.GetObject(db.id, OpenMode.ForWrite) as DBDictionary;


    // Remove filtros antigos com mesmo nome (opcional)

    if (filterDict.Contains("CIVIL"))

        filterDict.Remove("CIVIL");


    if (filterDict.Contains("ELMEC"))

        filterDict.Remove("ELMEC");


    // Cria o filtro CIVIL

    Teigha.LayerManager.LayerFilter civilFilter = new Teigha.LayerManager.LayerFilter();

    civilFilter.Name = "CIVIL";

    civilFilter.FilterExpression = "Name ~ \"cv*\"";


    // Cria o filtro ELMEC

    Teigha.LayerManager.LayerFilter elmecFilter = new Teigha.LayerManager.LayerFilter();

    elmecFilter.Name = "ELMEC";

    elmecFilter.FilterExpression = "Name ~ \"em*\"";


    // Adiciona filtros ao dictionary

    filterDict.SetAt("CIVIL", civilFilter);

    filterDict.SetAt("ELMEC", elmecFilter);


    tr.AddNewlyCreatedDBObject(civilFilter, true);

    tr.AddNewlyCreatedDBObject(elmecFilter, true);


    tr.Commit();


    ed.WriteMessage("\nLayer Filters criados com sucesso!");

}

}
