大家帮我看看这个源码，为什么只对直线起作用，圆和圆弧怎么用不了。

这是一个变双线的代码，默认是0.3，当宽度大于0.7时，两头会自己封口。可是有个弊端，就是只对直线起作用，圆和圆弧怎么用不了。哪位高手能帮忙改一下，使圆和圆弧都能用。在这里先谢谢了。

程序改了，再试一下。

请提供所缺函数，否则无法调试。

xiao88gang 发表于 2016-10-6 14:48:30

我也不知道函数，这个是在R14下用的插件。那就算了，不弄了，还是要谢谢你的热心帮助。

(mapcaqr 'setvar '("cmdecho" "bilipmode" "pickfirst" "osmode") '(0 0 0 0))
Try ===>
(mapcar 'setvar '("cmdecho" "bilipmode" "pickfirst" "osmode") '(0 0 0 0))

根据楼主提供的程序和所提的问题，基本可以认为，程序不是自己写的
当然，不是说不能用别人的程序进行修改以达到学习的目的，实际上我也经常把别人程序改成自己需要的
起点和过程不重要，最重要的是结果：自己确实学到东西而不是有了一大堆自己需要的程序
