关于Teigha的偏移,求助高手,在线等

private void button1_Click(object sender, EventArgs e)
{
using (Services ser = new Services())
{
string filename = "E:\\aaa.dxf";
Database db = new Database();
using (var trans = db.TransactionManager.StartTransaction())
{
BlockTableRecord btrec = trans.GetObject(db.CurrentSpaceId, OpenMode.ForWrite) as BlockTableRecord;
Circle cir = new Circle();
cir.Center = new Point3d(0, 0, 0);
cir.Radius = 500;
btrec.AppendEntity(cir);
trans.AddNewlyCreatedDBObject(cir, true);
DBObjectCollection ids = cir.GetOffsetCurves(20);
foreach (Entity ent in ids)
{
btrec.AppendEntity(ent);
trans.AddNewlyCreatedDBObject(ent, true);
}
trans.Commit();
db.DxfOut(filename,1,DwgVersion.AC1015);
//db.SaveAs(filename,DwgVersion.AC1015);
db.Dispose();
this.Close();
}
}
}
}
}
这段代码中圆能正确画出并显示,可是偏移后的圆却怎么都没有,到底是哪里出了问题,请高手指点一下。 没人知道吗? 调试的结果是ids的Count==0
估计Teigha没有实现这一功能,,,这在Teigha里是常见的
谢谢!!!原来是这样啊。
