快速改变夹角

lucas_3333 · 发表于 2014-6-20 19:35

我有一个关于直线快速旋转（改变夹角）的想法，用lisp完成行么？就是两条直线，相交的，运行命令后，选择第一条直线（固定不动的），选择第二条直线（需要旋转的），然后显示：当前角度为xx度，请输入新角度，输入新角度后，就让第二条直线绕交点旋转使两线的角度等于输入的角度.

仅仅是直线？

如果加上ＰＬ线，行吗？如果算上ＰＬ线，那也只能是针对两个点的PL线吧

edata · 发表于 2014-6-20 19:59

都是可以的。
直线边，无凸度。

谢谢e大，

下图中，如果选择左边的线为第一条线，右边的为第二条线，就可以正确更改
如果选择右边的线为第一条线，左边的为第二条线，这样改角度就总是不对了
