初级问题
在没有激活命令的情况下，如何将定义设置为最后选定的对象？请原谅我的简单lisp示例：
（命令“_move”“L”
在这个例子中，我只是指出我所说的最后一个对象是什么意思。
艾伦，
我肯定它在你和我共享的文件中，但我找不到它 “L”不提供最后选择的对象，它提供创建的最后一个实体；也可通过（entlast）访问 呃。。。我对Lisp一点都不熟悉，所以如果我遇到了一些我不知道的东西，请原谅我-但是如果你点击P并且“选择对象”，提示你得到最后一个（上一个）选择。。这就是你想要的吗？ (ssget "_P")
仅供参考：Alan:wink：
很抱歉。阳光照在我的眼睛里

当我试图快速回复时，突然弹出一条消息，这让我笑了起来
正在发送快速回复-请稍候 没什么大不了的。这并不困扰我；我只是想从一开始就消除这种混淆。
你得到你想要的了吗？ 它产生了
; 错误：语法错误
它应该像（setq x（ssget“_P”）一样简单吗 对我来说效果很好。检查拼写错误。 我想我的问题是（（））。。现在我明白了
; 错误：错误的参数类型：consp 好的，我正在编辑这个代码。这段代码正是我需要的，但我不想用鼠标选择一条线，而是想选择上一个对象。
