Creating new dxf with xdata

[Timo]

Hi

I have to create DXF file which must have some extdata/xdata strings assigned to objects (polyline, polygon and region). I have tried to use SetExtData, but it doesn't seems to work as I expected.
Could you give some example how to do this?

I'am using CAD VCL Enterprise 14.0

Hello Timo,

First you should add the ExtData unit to the Uses section, then create an object:

Code: Select all

vData:= TsgCADExtendedData.Create(acR14);

add a string to it:

Code: Select all

 vData.AddString(1000, 'my entity');

After it you add vData through the SetExtData method in vLine (class instance of TsgDXFLine):

Code: Select all

 vLine.SetExtData(vData); // setting vData

Code example;

Code: Select all

  vData:= TsgCADExtendedData.Create(acR14); // acR14 -- TsgDWGVersion
  vData.AddString(1000, 'my entity');   // adding a String type exData
  vLine.SetExtData(vData); // setting vData

Best wishes and Merry Christmas,
Catherine,
