It is something like this, this should help for the start.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
BlockTableRecord btr = (BlockTableRecord)myT.GetObject(db.CurrentSpaceId,
OpenMode.ForWrite, false);



Circle MeasuringPoint = new Circle(InsertPoint, new Vector3d(0, 0, 1),
Radius);

btr.AppendEntity(MeasuringPoint);

myT.AddNewlyCreatedDBObject(MeasuringPoint, true);

ObjectIdCollection IDColl = new ObjectIdCollection();

IDColl.Add(MeasuringPoint.ObjectId);


Hatch MeasuringHatch = new Hatch();

MeasuringHatch.SetHatchPattern(HatchPatternType.PreDefined, "SOLID");

btr.AppendEntity(MeasuringHatch);

myT.AddNewlyCreatedDBObject(MeasuringHatch, true);

MeasuringHatch.Associative = true;

MeasuringHatch.AppendLoop(1, IDColl);

Hai,

thanks roland its working fine.

But the hatch and circle is taken as a seperate entity when I move with the help of the mouse, but I need both hatch and circle to act as a same entity.

It mean after creating my program when I move the circle with the help of the mouse the hatch should also be moved simultaneously,

The hatch should be associative. If you move the circle the hatch should
stay in the circle. For me it works.

Hai

Thanks for the reply and support...

But when I try your code both the hatch and the circle is taking as a seperate entity. I don't where I am going wrong.

Plz check the below code which is what i tried.

Code:
----------
AcadDb.Circle circleobj = new AcadDb.Circle(new Autodesk.AutoCAD.Geometry.Point3d(30, 10, 0),Autodesk.AutoCAD.Geometry.Vector3d.ZAxis, 5);

AcadDb.Database db = AcadApp.DocumentManager.MdiActiveDocument.Database;

Autodesk.AutoCAD.DatabaseServices.Transaction tm = db.TransactionManager.StartTransaction();

Editor ed = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument.Editor;

try
{
AcadDb.BlockTable bt = (AcadDb.BlockTable)tm.GetObject(db.BlockTableId,AcadDb.OpenMode.ForRead);
AcadDb.BlockTableRecord btr = (AcadDb.BlockTableRecord)tm.GetObject(AcadDb.HostApplicationServices.WorkingDatabase.CurrentSpaceId,AcadDb.OpenMode.ForWrite);

btr.AppendEntity(circleobj);
tm.AddNewlyCreatedDBObject(circleobj,true);

AcadDb.Hatch hatch = new Autodesk.AutoCAD.DatabaseServices.Hatch();

AcadDb.ObjectIdCollection objcol = new Autodesk.AutoCAD.DatabaseServices.ObjectIdCollection ();
objcol.Add(circleobj.ObjectId);
hatch.SetHatchPattern(AcadDb.HatchPatternType.PreDefined, "SOLID");

hatch.ColorIndex = 4;

btr.AppendEntity(hatch);

tm.AddNewlyCreatedDBObject(hatch,true);

hatch.Associative = true;

hatch.AppendLoop(1,objcol);

tm.Commit();





}
catch(Exception ex)
{
throw ex;
}
finally
{
tm.Dispose();
}



Thank you,

Hi

Can anyone expand on this and demonstrate the more complex case of a polygon (or more) within a polygon, where the inner ones are not filled

Tks
