cad二开中提交事务前可动态显示实体图形，方法如下：

主代码：

        public static void Redraw(this Editor ed, Entity? ent = null)
        {
            using (ent?.ForWrite())
            {
                ent?.Redraw(BrightEntity.RecordGraphicsModified | BrightEntity.RecomputeDimensionBlock | BrightEntity.Draw | BrightEntity.MoveZero);
                ed.Redraw(BrightEditor.UpdateScreen);
            }

            Autodesk.AutoCAD.ApplicationServices.TransactionManager transactionManager = Autodesk.AutoCAD.ApplicationServices.Core.Application.DocumentManager.MdiActiveDocument.TransactionManager;
            transactionManager.QueueForGraphicsFlush();
            transactionManager.FlushGraphics();
           //Application.DoEvents();//目前不可用
        }
        public static void Redraw(this Editor ed, BrightEditor bright)
        {
            if ((bright & BrightEditor.UpdateScreen) == BrightEditor.UpdateScreen)
