修改块定义后，刷新块参照显示

void refreshBlockReference(AcDbBlockReference * pBlkRef)
{
	if (pBlkRef == NULL)
	{
		return;
	}
	pBlkRef->recordGraphicsModified(true);
	actrTransactionManager->queueForGraphicsFlush();
	actrTransactionManager->flushGraphics();
	acedUpdateDisplay();
}

记得关闭pBlkRef！

 

实在不行，请发送regen命令！
