AutoCAD .NET :: Capture Real Point Of Line Within Block?

How to capture the real point of a line within a block?

I used the following method to captured some entities  from a block.

I need the point of the entities, to redesign a dimension.

But if I move the original block, and then run my program. The dimension is redesigned in the original location of the block.

Basically the code looks like this:

 private void FilterDimension() { TypedValue[] typedValue = new TypedValue[2]; typedValue.SetValue(new TypedValue((int)DxfCode.Start, "INSERT"), 0); typedValue.SetValue(new TypedValue((int)DxfCode.LayerName, "Dimension"),
