Creating a Multi Line Style

By Virupaksha Aithal

Multi line style is stored in the named object Dictionary. You can get the Multi line named object Dictionary id using “Database::MLStyleDictionaryId” property.

Below codes demonstrates the adding a new Multi line style to the Multi line Style dictionary.

[CommandMethod("createmlinestyle")]
public void createmlinestyle()
{
    Document doc = Application.DocumentManager.MdiActiveDocument;
    Editor editor = doc.Editor;
    Database db = doc.Database;
    using (Transaction Tx =
        db.TransactionManager.StartTransaction())
    {
 
        DBDictionary mlineDic = 
            (DBDictionary)Tx.GetObject(db.MLStyleDictionaryId, 
                                              OpenMode.ForRead);
        if (!mlineDic.Contains("TEST"))
        {
            mlineDic.UpgradeOpen();
            MlineStyle mlineStyle = new MlineStyle();
            mlineDic.SetAt("TEST", mlineStyle);
            Tx.AddNewlyCreatedDBObject(mlineStyle, true);
 
            mlineStyle.EndAngle = 3.14159 * 0.5;
            mlineStyle.StartAngle = 3.14159 * 0.5;
            mlineStyle.Name = "TEST";
            Autodesk.AutoCAD.Colors.Color Color;
            Color = 
                Autodesk.AutoCAD.Colors.Color.FromRgb(255, 0, 0);
 
            MlineStyleElement element = 
                    new MlineStyleElement(0.25, 
                                        Color, 
                                         db.Celtype);
            mlineStyle.Elements.Add(element, true);
            element = 
                    new MlineStyleElement(-0.25, 
                                        Color, 
                                        db.Celtype);
 
            mlineStyle.Elements.Add(element, false);
        }
 
        Tx.Commit();
    }
