本文介绍了一个用于获取指定对象插入点位置的方法。通过使用AutoCAD API，该方法可以在交易开始时获取到BlockReference对象的位置信息。

        /// <summary>
        /// 获取插入点
        /// </summary>
        /// <param name="objectId"></param>
        /// <returns></returns>
        private static Point3d GetPosintion(ObjectId objectId)
        {
            Point3d point3D = new Point3d();
            Document doc = Application.DocumentManager.MdiActiveDocument;
            Database db = doc.Database;

            using (Transaction trans = doc.TransactionManager.StartOpenCloseTransaction())
            {
                //Entity ent = trans.GetObject(objectId, OpenMode.ForRead) as Entity;
                //point3D = ent.Position;
                BlockReference blkRef = trans.GetObject(objectId, OpenMode.ForRead) as BlockReference;
                if (blkRef != null)
                {
                    point3D = blkRef.Position;
                }
                trans.Commit();
            }

            return point3D;
        }
