求助老师们帮写一个程序，直线两端延长再两端拐角
本帖最后由 loveu515 于 2023-5-26 09:45 编辑求助老师们帮写一个程序，直线两端延长（两端延长的数值是一个变量，输入延长的长度，带记忆功能）再两端拐角（拐角长度也是变量，拐角是和直线垂直的，输入拐角长度，带记忆功能），然后再把这三条线段合并成多段线。谢谢啦。

) 路过的大神帮帮忙，就是输入直线的延长值和垂线的长度，然后把这3个线段合并:P- 加qq1005144760 start4444 发表于 2023-5-26 13:13

非常感谢帮忙！我用的时候发现，直线必须是水平的，画出来的垂线才对，延长值是带记忆上一次的，但垂直值不是上一次的，垂直值不输入的话一直都是50。可能是我没表述清楚，我想要的是：任何角度的直线，执行命令后两端延长再加两端垂线（垂线是与该直线垂直)，再删除掉原来的直线。
如果可以的话，可不可以做成既能选择直线，又能选择多段线呢？有时候也碰到直线是多段线的情况。给添麻烦啦:loveliness::loveliness:。

非常完美了！能把原来的直线在程序中删掉吗？ start4444 发表于 2023-5-24 10:49

能不能再帮下忙，改成连续选择呀？用的时候发现选完一条直线后，命令就结束了，再选其他直线，需要重新启用命令 这样可以连续选择了
