之后检索该区域…-你用它来划分你的主要区域，然后显示该区域。 有关详细信息，请参阅所附视频。。。
AreaDiv。拉链
好啊我们现在想要的是一个目标区域。。f面积为1000平方米。。只需要350平方米。。如视频所示，你可以把它放在任何你想要的地方。。
好的，这更好：

干杯
奥利弗
你在说什么？
我对原来的帖子还不满意吗？ 李-
你的习惯对我不起作用，所以我不确定。。。
但是从之前的帖子中，你似乎忽略了用户需要输入一个目标区域——例如，最终的隔离区域需要是“1000平方英尺”——并且例程会计算出在何处放置分界线，以创建具有该区域的分区。
可能需要一些迭代。 该问题的解决方案是Civil 3d或其他民用软件（如Civilcad）中地块选项的一部分。
你有多种选择来创建地块、平行线、旋转方向、临街距离等，这些AK用于所需区域，如上所述，迭代以找到解决方案。有非常快的使用。
因此，lisp程序需要将行答案迭代到一个容差。如果公制单位为1mm。 哦，一定是错过了那篇帖子/听不懂。
不过我只是想升级我的另一个LISP

我也不确定，但在我的第一篇帖子中就说了。
对奥利弗来说，你发布的第一个例程不是做了你想做的吗？我让它工作了，但是有点难按照提示。
