分割矩形
你好我想用lisp把一个矩形分成相等的小矩形。
应该像这样工作：
第一次单击：选择矩形
第二次点击：询问分区数
在lisp之后，应在原始矩形内绘制小矩形，并删除原始矩形
谢谢 我无法帮助您使用lisp，但我相信，您需要指定沿每个轴的分割数。 对
也许这有帮助。 这个怎么样？ 谢谢，这工作得很好，但在使用它之前，我需要每次将ucs更改为object。
在李的网站上，它说它适用于所有UCS/视图。
我怀疑您可能误解了必须将UCS重置为OBject。
您知道，您也可以在没有预先存在的矩形或其他几何体的情况下运行它吗？ 这是真的。该lisp将网格与当前Ucs正交
有一个问题。例如：您有30个具有不同方向/旋转的矩形要分割。需要在每个矩形中设置ucs对象，然后使用DGrid/DGrid lisp。这意味着要键入30次：
ucs->对象->拾取矩形->DGrid，然后再次ucs->对象->拾取矩形->DGrid等。。。。 现在我明白你的意思了，你需要重置后续矩形的UCS，这些矩形不在同一UCS中。
这更有道理。 我修复了UCS问题。。。。现在，我可以在绘制网格之前选择UCS，然后返回到最后一个UCS。也许这种代码格式不太好，但效果很好。我对lisp代码的了解有限。
现在我想：
1、只需拆除电网外线
我不明白我该怎么办
