Hi,

About color, to pass an integer as color index, you have to use the ColorMethod.ByAci.

About line weight, you have to use a member of the LineWeight enumeration or its corresponding integer.

public static ObjectId AddLayer(string name, double lineweight, int color) { var doc = app.DocumentManager.MdiActiveDocument; var db = doc.Database; ObjectId idx; using (Transaction tr = db.TransactionManager.StartTransaction()) { var layerTable = (LayerTable)tr.GetObject(db.LayerTableId, OpenMode.ForRead); if (layerTable.Has(name)) { idx = layerTable[name]; } else { var layer = new LayerTableRecord(); layer.Color = Color.FromColorIndex(ColorMethod.ByAci, (short)color); try { layer.LineWeight = (LineWeight)(int)(lineweight * 100); } catch { layer.LineWeight = LineWeight.ByLayer; } layer.Name = name; layerTable.UpgradeOpen(); idx = layerTable.Add(layer); tr.AddNewlyCreatedDBObject(layer, true); } db.Clayer = idx; tr.Commit(); return idx; } }

Sorry but I do not understand what you mean. The code I posted works as expected here.

Either you copy the whole code or you only adapt the Color and LineWeight expressions to your code.
