Change Block name (EntName)

[Sing]

Hello

I want to modify the block name(EntName) created before loading the CADDimension created in the code that creates the dimension line. The problem is that when a block with the same EntName already exists in the drawing, if AddEntity() is executed after Loads(dimension), it is overwritten.

Code: Select all

var dimension = new CADDimension();
...
// Is it possible to change the EntName of dimension which will be the EntName of block?
...
cadImage.Converter.Loads(dimension);
cadImage.Layouts[0].AddEntity(dimension);

Thank you

Hello,
Please, have a look at the code snippet below, illustrating how to create three dimensions, the name of first block is changed to testnameblock:

Code: Select all

private void button1_Click(object sender, EventArgs e)
        {
   if (cadImage == null) return;   
   AddDimensionStyle();
   AddDimensionAligned();
   AddDimensionRotated();
   CADDimension dim = cadImage.CurrentLayout.Entities[0] as CADDimension;
   dim.Block.Name = "testnameblock"; // changing block's name
   dim.Loaded(cadImage.Converter);
   cadPictBox.Invalidate();  
        }

  private void AddDimensionAligned()
  {
   CADDimension vDimension = new CADDimension(CADDimension.DimensionType.Aligned,
     new DPoint(148, 219, 0), new DPoint(66.7, 135, 0), 40, false);
   vDimension.Style = this.cadImage.Converter.DimensionStyleByName("TEST");
   vDimension.Layer = this.cadImage.Converter.LayerByName("0");
   vDimension.Color = Color.Brown;
   vDimension.TextOffset = 2;
   PlaceEntity(vDimension);
  }

  private void AddDimensionRotated()
  {
   CADDimension vDimension = new CADDimension(CADDimension.DimensionType.Rotated,
        new DPoint(66.7, 135, 0), new DPoint(148, 219, 0), 30, true);
   vDimension.Style = this.cadImage.Converter.DimensionStyleByName("TEST");
   vDimension.Layer = this.cadImage.Converter.LayerByName("0");

   PlaceEntity(vDimension);

   vDimension.LinDefPoint2 = new DPoint(66.7, 135, 0);
   vDimension.DefPoint = new DPoint(50, 120, 0);
   vDimension.Layer = this.cadImage.Converter.LayerByName("0");
   vDimension.Color = Color.Orange;
   vDimension.TextOffset = 2;
   PlaceEntity(vDimension);
  }

  private void AddDimensionStyle()

   vDimStyle.Scale = 1;
   AddEntToSection(ConvSection.DimStyles, vDimStyle);
  }

    vLayout = this.cadImage.Layouts[0];
   else

   if (vLayout == null) return false;

   this.cadImage.Converter.Loads(aEntity);
   vLayout.AddEntity(aEntity);

   return true;
  }
  private void AddEntToSection(ConvSection aSection, CADEntity aEntity)
