Hatch with transparency

[danny.boy.1]

Hello

Maybe someone can help me.

Is posible to add on drawing hatch (one color) with
transparency?

I want to fill some entities with transparent color.

I am sending attachment with example (selection rectangle in autocad).

Best regards,
Danijel Ivankovic

You can use the entities transparency property

  [CommandMethod("TestTransparencyHatch", CommandFlags.Modal)]
        public void TransparencyHatch() 
        {
            Database db = HostApplicationServices.WorkingDatabase;                   
            using (Transaction tr = db.TransactionManager.StartTransaction())
            {
                BlockTable bt = tr.GetObject(db.BlockTableId, OpenMode.ForRead) as BlockTable;               
                BlockTableRecord btr = bt[BlockTableRecord.ModelSpace].GetObject(OpenMode.ForRead) as BlockTableRecord;
                    foreach (ObjectId btrObjId in btr)
                    {
                        Entity ent = btrObjId.GetObject(OpenMode.ForRead) as Entity;
                        if (ent is Hatch)
                        {
                            ent.UpgradeOpen();
                            Autodesk.AutoCAD.Colors.Transparency trpy = new Autodesk.AutoCAD.Colors.Transparency(40);
                            ent.Transparency = trpy;                    
                        }         
                }
                tr.Commit();
            }           
        }

Pozdrav!

Lijepo je vidjeti da postoji na ovom forumu neko i sa "naših" prostora :-)!

Htio sam dodati na model terena koji se sastoji od SubDMesh objekta

transparentnost.

Ta mogućnost postoji tek od verzije AutoCAD 2011.
