double scale =2;  //需要放大 or  缩小的倍数
                              BlockReference br = ent as BlockReference;
                              // 1、改属性块比例
                              Matrix3d sMtx = Matrix3d.Scaling(scale, br.Position);
                              br.TransformBy(sMtx);
                              //
                              // 2、该属性块值                               foreach (ObjectId adId in br.AttributeCollection)
