Determining block scaling behavior

By Virupaksha Aithal

The BlockScaling property of a block will allow you to determine block scaling setting. Below code prints names of the blocks which are created with uniform scaling option.

[CommandMethod("FindBlockScaling")]

public void FindBlockScaling()

{

    Document doc = Application.DocumentManager.MdiActiveDocument;

    Database db = doc.Database;

    Editor ed = doc.Editor;

 

    using (Transaction Tx = db.TransactionManager.StartTransaction())

    {

        BlockTable bt = (BlockTable)Tx.GetObject(db.BlockTableId,

                                                  OpenMode.ForRead);

 

        foreach (ObjectId id in bt)

        {

            BlockTableRecord btr = Tx.GetObject(id,

                          OpenMode.ForRead) as BlockTableRecord;

 

            if (btr.IsLayout)

                continue;

 

            if (btr.BlockScaling == BlockScaling.Uniform)

            {

                ed.WriteMessage(btr.Name + "\n");             

            }

        }

 

        Tx.Commit();

    }

}
