Support for ExtendedData

[nthangaraj]

I wanted to know id CAD.NET support Extended Data for an Entity. If so please let me know how i can access it.

IvanCAD (http://www.ivancad.com/) has that functionality.

Code: Select all

 foreach (Ivan.DrawingEntity drawingEntity in objEntities)
            {
                if (drawingEntity.HasXData == true)
                {
                    try
                    {
                        objXData = drawingEntity.ExtendedData[REGISTEREDAPPNAME];
                    }
                    catch (Exception)
                    {
                        continue;
                    }
                                      ProcessLightweightPolyline((Ivan.LightweightPolyline)drawingEntity, objXData);
                }
            }

private void ProcessLightweightPolyline(Ivan.LightweightPolyline polyline, Ivan.RegAppExtendedData xdata)
        {
            string strXDataValue;                       
            //
            // extract the xdata
            //
            if (xdata.DataItems[0].DataType == STRINGTYPE)
            {
                strXDataValue = (string)xdata.DataItems[0].Value;
            }
            else
            {
                strXDataValue = "Error: wrong xdata data type";
            }

            m_objWriter.WriteLine("xdata: " + strXDataValue);
           
        }

Hello,

At the moment CAD .NET doesn't support Extended Data for an entity, this feature will be available in a new version of the library.

Does the Editor support ExtendedData? I'd like to attach a name to an entity, such as a polyline.

Hi,
CAD .NET supports adding ExtendedData. Please, have a look at the code example below:

Code: Select all

private void menuItem10_Click(object sender, EventArgs e)
  {
   if (cadImage == null) return;
   var poly = cadImage.SelectedEntities[0] as CADPolyLine;
   poly.ExtendedData.Add(new Xtome("testExtData"));
   poly.ExtendedData[0].Records.Add(Xdata.CreateRecord(1000, "PolyLineName"));
   poly.Loaded(cadImage.Converter);
  }

Best wishes,
Catherine.

Hi,
CAD .NET supports reading ExtendedData from DWG.
I use this code, but no extended data found.
I can see the extended data in AutoCAD.

string filename = "c:\\test.dwg";

CADImage image = CADImage.CreateImageByExtension(filename);
image.LoadFromFile(filename);

foreach( var entity in image.Converter.Entities )
{
foreach( var data in entity.ExtendedData )
{

}
}

Hi,
well, CAD .NET supports ExtendedData, so it should be read. Anyway, could you send me your file where you don't find extended data at support@cadsofttools.com, so I could examine the file?

Hi,
Thank you for the sent file.
Our libraries support AutoCAD files, but they may not read all the information from the files generated from other third-party programs, e.g. AutoCAD Map 3D.
